Build your own, design your own … Nowadays, we can design just about anything to reflect our personality — shoes, clothes, cell phones. And the boating industry is no different. At least for Dutch service-oriented shipyard ScheepsReparatie Friesland (SRF), which builds and restores craft completely to customer specs, completely in house. So their customers can roam the water in their own, personal style.

intensive but rewarding. The Phoenician, SRF’s most recent project, is a prime example of a customized craft. Previously a traditional steel workboat, it now serves as a luxury houseboat.

Restoration of the Phoenician was an intensive process requiring a meeting of the minds and mutual trust, according to Wychard Raadsman, owner of SRF. Wychard first explored ideas with the customer and then worked out design and refurbishments. “I love sharing that creative process with the customer and

working towards a unique goal,” he says with a smile. Regular visits to the shipyard showed the customer how the ideas were taking shape. “Occasionally we had to rethink original ideas because they didn’t work well or give the desired result,” explains Wychard.

practice makes perfect. After 1½ years of hard work, the 15.75-m (51.5 ft.) Phoenician is now touring the French inland waterways. Two trial runs with the John Deere 4045TFM engine have proved that this supposedly “light” engine is definitely up to the task. “I wasn’t convinced at first that it could drive the 15 kW (20 hp) rudder and run the craft smoothly,” says Wychard. “But a 6-cylinder was too bulky, so we agreed to give it a try — and it did the job.”

“A good return on investment” is how Wychard describes John Deere engines: “They have a durable engine block, and no bells and whistles that can break down. Spare parts are well-priced

driving innovation. Working closely with designers and customers results in some interesting innovations: the Phoenician boasts a telescopic spud pole that serves as an anchor. Unlike a traditional anchor, it keeps the craft in position without mooring ropes. An electric drive system, in combination with a small generator, allows the craft to “go green” for three hours at a continuous speed of 6 km/hr (3.7 mph).

In the meantime, Wychard has already embarked on his next challenge: refurbishing a 30-m luxury craft. “A John Deere 184-kW (247 hp) engine is definitely in the cards!” he concludes.

SRF works closely with designers and customers to create an optimal craft, like the Phoenician.

After evaluation, the PowerTech 4045TFM was found to be perfect for the job.

Characterized by its vibrant towns, colorful cuisine, and a crystalline coastline, the Mediterranean has many jewels in its crown. But for some visitors, the object of their desire offers something more. For one Russian sea and sailing enthusiast, the reliable Comet 100 by Comar Yachts is the ideal way to take on the waves and enjoy the tranquility. For him, this cruising sailboat is the jewel in the Mediterranean crown.

Going beneath the surface. For a complete sailing experience, the owner of the Comet 100 needed the best partners during the design of the boat. With a built-to-order philosophy, the interior was developed in partnership with award-winning Italian designers at Studio Vallicelli. All the carpentry and millwork was created by specialized Comar Yachts workshops. But to achieve total comfort, the answer is in the ride.

Comar Yachts is dedicated to building powerful and reliable sailboats, but their Comet 100 is a different breed. Identifiable by its pleasing aesthetic line, the Comet 100 measures 31 m (101.7 ft.) long, making it the biggest boat the company builds. A vessel this size requires an engine with high torque and agility to power the airex and fibreglass sandwich hull with little displacement. So, the manufacturers partnered with engine experts: John Deere engine distributor Rama Motori S.p.A and its local dealer Powerline S.r.l.

italian taste for perfection. For travelling long distances and taking time to discover the delights of the Mediterranean, the Comar Yachts team chose the PowerTech 6081AFM engine with high torque and great reliability. But also John Deere’s excellent service network and the proximity of Powerline S.r.l., located in Rome, were decisive factors. The Comet 100 is made to cruise, so readily available services throughout the Mediterranean are a must.

Working closely with Powerline S.r.l., Comar Yachts was impressed by the John Deere 6081AFM engine both technically and commercially. “It was a perfect fit for the design and no modifications were needed,” says Paolo Ceccarelli, general manager at Powerline. “Whether it’s weaving between sandy coves or powering through the surf, this high-performance sailboat found the engine it was looking for.”

Italian elegance and excellence are set to impress this lucky Russian owner before the vessel’s expected launch date in July 2011. Looking ahead, a new Comet 100 is on the horizon for another seafaring aficionado. Due to a successful partnership, John Deere is positioned to power the new yacht and take to the sea once again.

The key to any successful business is maintaining a steady customer base, so flexibility, personal care, and clear communication are essential. A touch of creativity doesn’t hurt, either. Altena Yachting B.V. understands this only too well. Since 1969, this family-run company has helped customers create their personalized dream yachts with good sailing qualities and all the comforts of home. And some homes are very comfortable! That’s why customers come back again and again.

delivering on promises. A customer from Luxemburg bought his first Altena craft, a 15.5-m (51 ft.) Altena Blue Water Trawler, in 2002. A John Deere 6068DFM engine with a Twin Disc MG 5011A transmission ensured smooth sailing around Palma de Mallorca.

Five years later, he decided on a larger craft, something even more comfortable. To find the one that would meet all his desires, he returned to Altena. The 18.5-m (61 ft.) Altena Explorer was fitted out to the customer’s specifications, with a spacious saloon, teak interior and hydraulic bow/stern thruster stabilizers. This time, a John Deere PowerTech 6081AFM engine was selected for main propulsion and for powering the hydraulic bow thruster.

Now, the customer is again ready to move up. He is discussing the purchase of a third Altena yacht: a 24-m (78.7 ft.) craft. His Altena Explorer is looking for a new owner, and with its high resale value, it is expected not to be on the market for long. The new yacht will also be tailored to his high standards and precise specifications. “Altena is open to my requirements, and they deliver on their promises,” the customer says. “That’s why I keep coming back.”

Altena’s range of cruisers caters to both the relaxed and the more adventurous sailor. The Excel, Family, and Canal Cruisers are ideal for leisure sailing in inland waters, while the Coastal Cruisers and Blue Water, Explorer, and Custom Trawlers are outstanding in open sea and rough sea. The steel and aluminum craft vary in length from 11 to 20 m (36 to 65.5 ft.).

loyalty extends to John deere. For this new yacht, it’s not surprising that Marcel Pols, Altena Yachting director, will again recommend a John Deere engine. Altena has been using John Deere engines for 17 years and is a true advocate of the brand. “Back in 1993, hydraulic attachments were becoming popular, and most engine brands simply couldn’t handle them,” explains Marcel. “A customer suggested John Deere; he knew their engines were reliable in agricultural applications.”

Since then, Altena has powered some 50 craft with John Deere engines, ranging from 100 kW (134 hp) to 205 kW (275 hp). “On our larger, ocean-going craft, we always install John Deere PowerTech 6081AFM engines. Customers never question this choice; they know they need a solid, reliable engine that can handle tough weather conditions,” comments Marcel.

Because John Deere engines keep on running, Altena hasn’t had much need for John Deere engine distributor Nagel Power Systems. “But when we do need them, they deliver on their promises, just as we do!”

PowerSource is pleased to feature an interview with Jean Pierre and Marie Dufour. Jean Pierre, a retired family practitioner, and Marie Dufour, a retired nutritionist, are owners of a new twin-engine catamaran they call Domino. After rearing their five children, the couple built the 20-m (66 ft.) motorcat passagemaker to cruise the oceans of the world and provide health and nutrition services to the most isolated islands of the South Pacific. In this article, the Dufours share their goals and travel experiences since the launch of this new John Deere-powered vessel in December 2009 in Asuncion, Paraguay.

powersource: What are some of the reasons why you decided to build the Domino?

Jean pierre: Our goal is to provide health missions to the most isolated islands of the South Pacific in coordination with the World Health Organization. Domino was designed and built to cruise and work in the South Pacific. We wanted a two-person liveaboard catamaran capable of cruising any ocean at a reasonable speed, with comfort, great reliability, and autonomy. We asked renowned catamaran designer Malcom Tennant to apply his lifetime experience in catamaran design, and he came up with the cruising machine called Domino.

powersource: What were some of your design goals for the Domino?

Marie: The boat had to be easily handled by only two people who were not professional mariners. We chose a motor catamaran over a monohull because we find cats more spacious. The cabin is arranged on one level: head, stateroom, galley, salon and pilothouse are all en-suite. This gives a very open feeling to the entire boat. With 25 windows, we have a full 360º view of our surroundings. It’s quite lovely!

Jean pierre: The boat had to be as reliable as possible, especially propulsion and anchoring. Function came first. Our John Deere engines had to perform to perfection and we have been able to get service whenever and wherever we needed it, the world over. Safety at anchor is assured with our two Ancora Latina anchors and a massive anchor windlass. A redundant electrical system and our ability to run our HRO watermaker, making 250 l (66 gal.) of fresh water per hour, meant autonomy on the open water.

Jean pierre: The engine powers the hydraulic steering. Alternators fitted on each engine

charge our house batteries and run the air conditioning and the HRO watermaker.

powersource: The Domino was built in Paraguay, and for the next several months, you cruised up the coast of Brazil toward the Caribbean. What was that like?

Marie: Cruising Brazil was an intense experience, not only because this was Domino’s maiden voyage but also because Brazil offers such a wide variety of cruising conditions. Quiet lagoons and treacherous reefs, secure island coves, and wild river currents, and—of course—the fearsome Amazon! We took advantage of the variety of sea conditions to fully test Domino.

powersource: How did she do?

Marie: Cruising the Bahia de Todos los Santos (Salvador) at 25 knots, standing on the foredeck and holding on to nothing else but my hat was a testimony to Domino’s stability and sea-keeping ability.

Jean pierre: Coming up the southern coast of Brazil, with 20 knots of wind and a strong current on our nose, Domino was happy cruising at 12 knots without excessive slamming or twisting. She just ‘sambas’ into the waves.

powersource: What are some of your most exciting or most memorable experiences on your trip so far?

Jean pierre: Entering Rio de Janeiro and anchoring in Guanabara Bay, with the Sugar Loaf on starboard and the Christ Redemptor on port. It’s quite impressive.

Marie: Anchoring off of the scarcely populated islands of Ilha George Grego by Ilha Grande, the Abrolhos Archipelago, or off of the Salvation Islands in French Guyana. Counting on the reliability of our engines and anchors allows us to get into remote anchorages.

powersource: How did you come about powering Domino with John Deere engines?

Jean pierre: We had read great reviews, especially one article in PassageMaker magazine a few years ago.

powersource: What engine characteristics topped your wish list?

Jean pierre: We wanted an engine that was quiet, reliable, with easy maintenance and worldwide service. We also wanted engines that would fit in the narrow space of Domino’s hulls, which were 1.20 m (4 ft.) at the widest point. Because of the difficulty it would be to remove the engine, we wanted an engine that can be rebuilt on site. The winning point was the fact that the John Deere engine’s cylinder liners are removable, as they are not part of the engine block. This makes major repairs, if needed, easier and cheaper than with other engines.

powersource: Now that you are well into your travels, how are the John Deere engines performing?

Jean pierre: Domino is an incredible cruising machine. The PowerTech 6081AFM delivers 224 kW (300 hp) per engine. The M2 rating allows us to run the engine for days on end. She loves to ride at 20 knots. The hum of the engine is pleasant, and at 20 knots at 2000 rpm, we do not have to raise our voice to be heard in the pilot room. But, most of the time we cruise at 12 knots, barely hearing the engine and

The high pressure rail system makes this a very quiet engine with high torque at low rpm to turn our large 34 in. (86 cm) props. In addition to being quiet, reliable, and fuel efficient, these engines are really easy to service. Also, there is no smell of diesel fumes anywhere around this boat!

powersource: What is the combined fuel consumption of the John Deere engines?

Jean pierre: Running 20 knots at 2000 rpm, we’re getting 26 gph. At 12 knots at 1300 rpm, that lowers the fuel consumption to just 9 gph (98 l/hr).

Marie: Overall, since we launched, and over 8,000 nautical miles, we’ve averaged a 13.5-knot speed and one mile per gallon.

powersource: Describe your experiences with John Deere engine specialists along the way.

Jean pierre: We first made contact with our John Deere engine distributor, Don Freeman of Bell Power Systems. But very quickly we dealt with Jobi Javellana, the head of South America’s operations, who guided us through our travels and referred us first to the fabulous Team Argentina in Rosario, then to Team Recife in Brazil, and now to Trintrac and Richard Blanc in Trinidad. Whatever our need, John Deere South America has been wonderfully responsive and has catered to us.

powersource: So your John Deere engine distributor got you in touch with the right people in Argentina?

Jean pierre: Alerted by Don Freeman, the entire John Deere Argentina took us under their wing when we reached Rosario (Argentina) and ran all our sea trials on the Rio Parana. Engineers Alberto Souto and Jose Echeverria let their service manager Eng. Dario Matijacevich run Domino through her paces. So we send big kudos to Don Freeman who never let us down and referred us to the John Deere division most able to help us, wherever we were.

Marie: I keep raving about the John Deere service and personal touch. Over the last four years, we’ve dealt with hundreds of brands and industries. Few have been as wonderful and responsive as John Deere.

powersource: What do you like most about your boating adventures?

Jean pierre: We enjoy being at sea. We like the challenge of crossings, the tranquility of being away from shore and the now-familiar rocking of the boat. We also enjoy the social life and interaction with other cruisers. It is a small community, and at every port we meet wonderful people. We share our adventures, difficulties, talk about the next port, play music, and sing folk songs in group — quite a change from the daily hassles and stresses of running a medical practice!

powersource: So where are you and the Domino headed in 2011?

Marie: We are now making our way up the Eastern Caribbean. Domino is our home, our work platform, our passion, and we love to see so many other people catching the Domino fever and making sure that we make her one unique, performing cruising machine!

Boat owners wanting a keel-cooled version of the popular 9.0L marine engine will take great interest in a new John Deere marine engine that will hit the water in 2011.

Make way for the PowerTech 6090AFM75 — a welcome addition to a great lineup of John Deere marine engines ranging from 213 to 317 kW (285 to 425 hp).

“The new 9.0L engine replaces the PowerTech 6081AFM keel-cooled marine engine and is an excellent choice for recreational trawler yachts, commercial vessels, and generator drive engines,” says Dave Flaherty, marine marketing manager for John Deere Power Systems.

The new 9.0L engine packs more horsepower per liter of displacement. With 317 kW (425 hp) at 2400 rpm, the PowerTech 6090AFM delivers 37 kW (50 hp) more than the 8.1L engine at the highest propulsion rating. Gen-sets will reap an additional 25 kW of power both at 50 and 60 Hz.

The new PowerTech 6090AFM is a keel-cooled version of the well-established seawater-cooled John Deere PowerTech 6090SFM engine — a marine engine that has proven itself time and time again in countless recreational marine applications across the globe.

“John Deere continues to expand the marine engine lineup with new models and higher horsepower ratings,” says Dave. “We designed the new 6090AFM75 to provide high power output from a compact engine while maintaining the legendary long-term reliability our customers have come to expect from John Deere marine engines.”

So here’s a snapshot of what’s to come.

There’s something about crystal clear turquoise blue waters and pearly white sandy beaches that seem to tug at Captain Gerry Cooper’s wanderlust these days.

It all started when he repowered his 14.6-m (48 ft.) custom trawler with a new PowerTech 6135SFM engine. Gerry’s aquatic world seemed to reopen, and he soon found himself frolicking in the beautiful Bahama Islands, a tropical archipelago of over 700 islands in the Atlantic Ocean southeast of Florida.

“After I got the new John Deere engine in November 2009, I took my first trip to the Bahamas. Now I’m hooked … I really am,” says Gerry, who moors the Roncador in St. Petersburg, Florida.

The Roncador is a longtime travel companion for Gerry, who purchased the Marine Management vessel in 1979. Designed by Jim Wynne and built by Lee and Jo Anne Brooks, the vessel features a sturdy, heavy-duty hull, and for many years, it served as a multipurpose charter boat. “Now it’s strictly for pleasure,” he says. “I’ve been to a lot of places with it, including the Panama Canal. I’m sentimental about the boat.”

Three decades of traveling took a toll on the Roncador’s original engine, and over time, the vessel became less suited for travel into pristine marine environments. “The original engine became a problem,” relates Gerry. “It got to the point that I could no longer go into most marinas because of the smoke and oily discharge in the water.”

Ready for a repower, Gerry was given the opportunity to install a prototype PowerTech 6135SFM — John Deere’s largest displacement engine with seawater aftercooling. “It’s a single-engine boat, so I wanted a reliable engine,” says Gerry. “I admit that I initially dreaded the thought of a repower, thinking it would be a chore, but it wasn’t. I quickly became comfortable with the skill level of my John Deere marine dealer and his expertise in installing the engine, and that added to my confidence in the John Deere engine and its reliability.”

Not only is the Roncador more reliable, she’s easier on fuel, too. “The fuel consumption of this 500-hp (373-kW) engine is really remarkable,” says Gerry. “I’m using just one-third of the fuel that I used to burn running the 356-hp (266-kW) engine.”

The new PowerTech 6135SFM turns a 26x28-inch (66x71 cm), four-blade prop through a Twin Disc transmission with a 2.5:1 gear ratio. The fiberglass hull features a semi-enclosed tunnel that directs water to the prop, enhancing the 14.5-t (16 US t) trawler’s ability to achieve an impressive top speed of 18 knots at 1950 rpm, “which is handy,” he says, “especially if you need to outrun weather.”

Gerry typically enjoys a cruiser’s pace, and he found Roncador’s sweet spot running 7.5 knots at 900 rpm. That’s where the PowerTech 6135SFM consumes just 9.5 l/hr (2.5 gph) of fuel. Gerry calculates that to be a miserly 1.5 l/nautical mile (.33 gallons per nautical mile). As a result, he’s more than doubled his boat’s range.

More range means more quality, uninterrupted cruising around those beautiful Bahamian Islands. Plus, Gerry no longer worries that his engine may be spoiling the pristine environment. In fact, Gerry says the newly repowered Roncador is a traveling testimony for the new PowerTech 6135SFM. “People are seeing the future (of emissions), and they are seeing my enthusiasm about the engine,” he says. “Seeing is believing.”

The PowerTech 6135SFM is carefully lowered for installation.

The Roncador keeps pristine waters clean thanks to its new PowerTech 6135SFM engine, which drives a 26x28-in. (66x71 cm), four-blade prop.

Gerry Cooper finds himself lured to the beauty of the Bahama Islands with his longtime travel companion, the Roncador.

The Alaska Quest was repowered with a new PowerTech 6081AFM marine diesel just months before the rescue.

It’s a rare event that a John Deere marine engine would assist in a rescue of wild deer, but that’s exactly what happened at Taku Inlet, Alaska, this past fall.

Tom Satre and his family were cruising aboard the Alaska Quest when they spotted four black-tail deer swimming toward their 19-m (62 ft.) charter boat.

Were the deer lured to the smooth call of the PowerTech 6081AFM marine engine? Not likely. The cold and tired deer were about 2 km

(1.2 mi.) from shore and just minutes away from drowning, looking for a desperate escape from the frigid water.

“They swam right toward the boat,” he said. “They were swimming in 2-ft. (60 cm) chop, unable to see over the waves. They were circling the boat and looking as if saying ‘help us, help us.’”

Tom knew something had to be done and did some fast thinking to get them onboard. “I formed a lasso with the mooring line and dropped it around their heads one at a time,” relates Tom. “They were about 85 pounds (39 kg), sopping wet. We were fortunate to have a low swim step at the stern, and I was able to pull them onboard. If we had to haul them over the side, I couldn’t have done it.”

Putting their wild, skittish instincts aside, the deer willingly came onboard and collapsed, too tired to even shake off the water. “They were absolutely gassed,” he recalls. “The last one was in really poor shape. He was very hypothermic. I massaged him for 20 minutes trying to warm him up. He bleated like a little lamb. I think he was appreciative.”

The Alaska Quest headed to Taku Harbor, and during the hour-long ride, one deer stood up. When the Alaska Quest arrived to harbor, the deer hopped onto the dock, looked back, then leapt into the waters of the harbor, swam to shore, and quickly disappeared into the forest. Two others followed suit, after a bit of prodding and assistance from the group. The last one had to be wheel-barrowed off the boat. Tom says all four deer survived the ordeal.

Although the event was unusual, it almost seems fitting for the Alaska Quest to be involved in that sort of mission. The vessel spends many cruising days giving eco-tours in southeast Alaska to view whales, porpoise, and bears. Swimming deer are more of a rarity.

Cold and tired, four tired young bucks approach the Alaskan Quest, looking to escape the water.

Tom Satre used his mooring line to lasso the deer and pull them on deck. The four deer lay exhausted aboard the Alaska Quest after being pulled from water.

With an appreciation for the environment, Tom chose to upgrade his vessel with a new a low-emissions, fuel-efficient PowerTech 6081AFM marine engine last spring. The new engine was purchased and installed by Mark Jochems of Shoreline Marine Diesel Inc. in Port Townsend, Washington. Mark paired the 224-kW (300 hp) engine to a Twin Disc transmission with a 3:1 gear ratio. The engine turns a 36x31-inch (91x79 cm) prop and consumes just 18.5 l/h (4.9 gph) at 8.7 knots at 1600 rpm.

“That’s phenomenal for a 60-ton (54 mt) boat,” says Tom of the steel-hull, full-displacement vessel. “The engine is phenomenally powerful. It has all of the power and torque I need. If I ask for 2200 rpm, I get it immediately.”

A love for Alaska and a passion for the environment, Tom and his wife, Tish, enjoy sharing their enthusiasm with others aboard the Alaska Quest.

“What we do is go out and see if clients can have as much fun as we’re having,” says Tom. “We get to show them what we love, and that’s Alaska. And it’s not just the beauty that they love, it’s the people who reside there, too.

“The people are pretty special here,” says Tom. “They’re willing to lend you a hand when you are in trouble.”

Certainly the four rescued deer could only agree.

Jim Seyler loves the smell of salt air.

Native to the Pacific Northwest, Jim has spent his life around the water, whether it was hanging out at the commercial fishing docks with his grandfather as a child or working his way through college aboard an ocean-going tugboat.

Today, Jim’s career as a financial consultant doesn’t stop him from having a piece of this past. He enjoys living on the water. In fact, his home literally floats on the banks of the Columbia River. Rather than a front yard, water flows like an avenue of escape from a long day of market analysis. And with just a punch of a garage button, Jim and his wife, Sandy, can board their 9.8-m (32 ft.) Grand Banks yacht and enjoy immediate retreat from a hard day’s work.

Jim says it was the classic style of the 1971 wooden Grand Banks trawler that caught his eye four years ago. “The boat was reminiscent to my grandfather’s 42-ft. (13 m) wooden salmon trawler,” recalls Jim. “I like an all-wood boat. I also prefer diesel motors.”

Jim also loves the thought of more extended trips into the ocean blue. When Jim and Sandy purchased the Grand Banks, it was in near-immaculate condition, yet they knew the 40-year-old engine would eventually need to be either rebuilt or replaced, especially if he’d ever venture much beyond Columbia’s riverbanks.

“It came down to these choices: rebuild it and still have old technology; replace it with a near identical twin; or step up to modern technology,” relates Jim of his decision. “It didn’t take me long to believe that it was the John Deere engine that I wanted.”

Jim contacted Multnomah Yacht Repair, a full-service boat yard and John Deere marine engine dealer, and there he purchased a new fully electronic PowerTech 4045TFM engine.

“I wanted an engine that would last as long as the boat — an engine that was state-of-the-art, proven, and low maintenance,” states Jim. “And this engine met that criteria.”

Removing the old 6-cylinder engine proved to be a “monster job.” Jim hired Independent Marine Repair to perform the repower in Scappoose, Oregon. With attention to detail, Jim had the engine and all of the vessel’s electrical wiring replaced.

Today, the engine room boasts a whole new look. The PowerTech 4045TFM, with its smaller displacement and footprint, gives much more space to the engine room. The engine is lighter and more powerful, too.

“The throttle is very responsive, she runs smoother and much quieter, and starts with the push of a button. And, there’s no smoke. I’m very pleased with the result.”

Although the new engine is also more fuel efficient, that’s not one of Jim’s priorities. It is the reliability and longevity of the John Deere engine that matters to him the most.

“Mechanically what I have now is very solid,” says Jim. “I am now comfortable taking this boat out into the Pacific Ocean, heading north to the San Juan Islands, and further up in the Inland Passage to Alaska. From a mechanical standpoint, I wanted an engine that was reliable — an engine I can trust. Weather permitting, now we can travel the oceans with confidence, knowing we have one of the most reliable diesel engines money can buy.”

Jim Seyler and his wife will enjoy extended cruises into the Pacific Northwest aboard the repowered Grand Banks.

Living the dreamA repower allows a Washington couple to become northward bound

Jim Bass has his sights on Alaska. As much as he and his girlfriend, Marla, enjoy their weekend travels to the San Juan Islands, the Anacortes, Washington, couple have been waiting for the chance to “work their way north” aboard the Dream Weaver.

Now they have the confidence to do it.

“We like to go into remote locations, and it’s nice to have a dependable engine to go up on these trips,” says Jim of his recently repowered 1961 Monk-designed yacht.

A year ago, Jim repowered the 11-m (36 ft.) Dream Weaver with a new PowerTech 4045TFM marine engine. Certainly it was time, he admits. The old two-cycle engine developed some bad habits over the years. It smoked badly, leaked oil, and rudely drowned out his conversations.

“Everybody would be enjoying a quiet summer morning drinking coffee, and we would start up to leave, and a big cloud of smoke would come out, and the loud noise would echo off the cliffs,” recalls Jim. “It was just nasty.” He also spent too much time in the

engine hatch checking oil levels. “People would joke saying ‘If your engine quits leaking oil, you better put more oil in it.’”

Ready to remove the old 2-cycle engine, Jim sought the advice of Wayne Gregg of Gregg’s Diesel, who suggested that Jim install a new 101-kW (135 hp) PowerTech 4045TFM engine. The repower included removing the old Twin Disc crash box and replacing it with a new Twin Disc 5011 transmission with a trolling valve. Using a 2.5:1 gear ratio, the transmission mounts to a 44-mm (1.75 in.) shaft that turns a 25x20 in. (635x508 mm), 3-blade propeller.

is this a dream? Now Jim peers into his engine compartment in near disbelief. Not only is the engine compartment clean, the new 4-cylinder engine measures almost a half a meter (20 in.) shorter than the old 6-cylinder block. His wheelhouse has a whole new look, too. A single electronic monitor displays all of his onboard functions.

The Dream Weaver will soon be Alaska bound with her new John Deere marine engine.

Jim Bass is ready to head north on his newly repowered 1961 Dream Weaver.

He particularly likes his newfound ability to electronically monitor and set the engine rpm to maximize fuel efficiency — something he was unable to do with his old engine. “There’s no more guesswork,” says Jim. “I know how much fuel I’m using per hour, and that’s neat.”

To maximize fuel economy, Jim runs 8 knots at 2100 rpm. At that speed, the 13.6-t (15 US t) Dream Weaver consumes 13 l/hr (3.5 gph) — a notable improvement over the old 123-kW (165 hp) engine that burned roughly 19 l/hr (5 gph) running at 1400 rpm.

It’s made the Dream Weaver more enjoyable in other ways, too. “You hit the button, and it starts right up,” says Jim. “And now we can actually hear the water when we’re cruising along.”

Jim admits to “dragging his feet” on the repower, over concern of converting to an electronically controlled marine engine. “But the John Deere engine proved me wrong,” says Jim. “It’s pretty darn reliable, and it’s made the boat more of a pleasure to take out. I’m tickled to death with it.”

When Richard Armstrong of Westport, Massachusetts, powers up his 21-m (70 ft.) Little Vigilant, an element of maritime history goes along for the ride.

Built in 1950 by Abeking and Rasmussen of Bremerhaven, Germany, the Little Vigilant is a custom motorsailer whose lineage traces to the Vigilant, a 30-m (100 ft.) sardine carrier-style vessel built in the 1930s by wealthy yachtsman Drayton Cochran of New York. When the Vigilant was rundown in the WWII war effort, Cochran had a smaller version of his vessel built. Designed by Walter McGinnis of Boston, the 30-m (70 ft.) Little Vigilant features a fold-down rig and a removable wheelhouse so that she could easily transit the canals of Europe during the Cochrans’ travels abroad.

The Little Vigilant spent a leisurely decade plying the inland waterways there, and was eventually sold and stored in Poole, England. There she sat for nearly a half century; that is, until Richard Armstrong came along.

“I have always loved sardine carriers,” says Richard. “They are seaworthy, easy to navigate, and perfect in looks.”

When Richard purchased the Little Vigilant, he cut no corners to restore those good looks. Renovated by Fairhaven Shipyard in Fairhaven, Massachusetts, the Little Vigilant received a complete makeover with paint and varnish. Richard also commissioned Nor’ east Marine Systems of Fairhaven to replace every pipe and wire. “I wanted to install all new systems — plumbing, wiring, refrigeration, navigation, heating, air conditioning — yet, I wanted to keep the interior original and true to her owners’ and designer’s original wishes,” relates Richard.

Richard also wanted a reliable, long-running engine that would power the Little Vigilant well into the future. “I was looking for a slow-turning, 4-cycle engine with an M1 or M2 rating,” says Richard. Researching engines, Richard found that John Deere engines are the power of choice for many friends who fished in Maine, as well as several high-end long-distance trawler manufactures, including Nordhavn, Grand Banks, and Kadey Krogen.

“Everything just pointed to John Deere,” Richard recalls. That’s when he contacted John Deere engine distributor Bell Power Systems and marine dealer R.A. Mitchell, and decided that he couldn’t steer wrong with a new PowerTech 6081AFM. “We sized it, did all of our calculations and propulsion data, and decided it was a perfect engine for the boat.”

Richard purchased the engine and hired Fairhaven Shipyard to install it. The 175-kW (235 hp) engine was paired to a Twin Disc transmission with a 3.33:1 gear ratio and fitted the shaft with a 38x30-in. (965x762 mm), 4-blade prop with a right-hand rotation.

“I’m extremely happy with the new engine,” relates Richard. “I really love it. The engine is great, and it’s twice the horsepower of my old engine, yet it’s quiet. We cruise 9.8 knots at 1650 rpm, and the engine uses only 43 percent of its power. And the electronically controlled fuel system on the John Deere engine is fantastic,” he adds. The Little Vigilant consumes a modest 25 l/hr (6.5 gph) at 1650 rpm. Richard calculates a long-distance range of 9,656 km (6,000 mi.) with 6814 l (1,800 gal.) of onboard fuel at lower rpm ranges.

That range makes the Little Vigilant prepared for some future blue water passages. “I do desire to travel into the Baltic and Mediterranean seas and the British Islands,” says Richard.

Restored and repowered, the Little Vigilant will surely take him there, and well into the future.

As the cold winter winds blow, we can only dream of summer in the south of France. But when the sunny weather comes, so do the sunbathers, packing the beaches “like sardines,” says Jean-Pierre Pradié of Toulon, France. He and his wife, Annie, escape the crowds and enjoy true far niente (pleasant idleness) on the Ceres, their 12.8-m (42-ft.) Grand Banks yacht. “We just head into the Mediterranean and find pure tranquility,” he comments.

a room with a view. The couple bought the Ceres, originally built in 1977 in Singapore, in 2000 from a neighbor. “It was really run down, and he fixed it up nicely,” recalls Mr. Pradié. “Now it’s very comfortable! Two cabins, including a large master cabin, a bath, a shower, and a dining room. And the 360º views from below are wonderful!”

original power. While the boat had been refurbished before the Pradiés bought it, the engines hadn’t been touched. The Ceres was, and still is, powered by its original John Deere 6404 engines. “I didn’t have to do anything to the engines themselves,” explains Jean-Pierre. To get the boat back to cruising condition, he replaced the starters,

the injectors, the feed pumps, and the water pumps. “I think that was only to be expected for a 30-year-old boat,” he says with a smile.

After 10 years of smooth sailing, the engines — now running for over 30 years — are still going strong. “They have about 3,300 hours on them, and we run them for 100 hours per year,” he explains. “We don’t have to sail far to get away from the crowds: we can get to Corsica in about 15 hours, going 16 km/hr (10 mph), for example. Or we can reach Elba in 20 hours. We’re not in a hurry. The islands will be there when we arrive!”

Fuel consumption remains very good. “At 16 km/hr (10 mph), I use only 14 l/hr (3.70 U.S. gph) for the two engines. That suits me perfectly. I don’t need to go 20 km/hr (12.4 mph), to save 45 minutes.”

Good parts and proper maintenance. For getting the Ceres into tiptop shape, Jean-Pierre appreciated the help of John Deere distributor Jeryh Trehel of Silenc’Air. “I knew about engines from working on sailboats I previously owned, but I’m not a specialist. Jeryh Trehel is a very good mechanic, and helped me find the parts I needed, which wasn’t always easy. Together, we keep the boat — and engines — afloat.”

Parts On-Board KitAdd confidence to your journey by stocking essential engine parts

Keep in mind that the exact spare parts you need really depends on the model of your John Deere engine and the extent of your travels. “What may be essential for cruisers of the Intercoastal Waterway may be different than for a passagemaker,” advises Joby Javellana, John Deere regional sales manager. “So consult your local John Deere marine dealer for a recommended list of parts for your specific engine and travel plans.”

Know your engine. “You owe it to yourself to become familiar with your engine, not only for the sake of gaining knowledge or conducting routine service, but also to perform repairs in mid-voyage, if necessary. Your John Deere operation and maintenance manual can be a wealth of information in times of need,” says Joby. Also, the John Deere Parts and Service Directory is your resource for locating a John Deere distributor or marine dealer during your travels.

Also, make sure to register your engine warranty, advises Matt Dewey, product manager of parts marketing for John Deere Power Systems. If your marine engine is registered, it streamlines the entire process if you have a warranty situation. So if you haven’t done so already, it’s easy to register by contacting your local John Deere distributor or service dealer. If you are in North America, you may also go to www.JohnDeere.com/warranty and click on “Warranty Registrations.”

Finally, you can count on genuine John Deere maintenance products to give you the best quality and value. Genuine John Deere replacement parts and products are specifically designed and engineered by John Deere for John Deere engines, says Matt. “Our parts restore the original quality and performance of your marine engines so that you can enjoy the journey with peace of mind.”

Visit your local John Deere marine dealer for a specific list of recommended parts for your vessel, engine model, and travel plans.

John Deere is sad to announce the passing of a very important team member of John Deere Power Systems (JDPS).

Tom Lekar of Waterloo, Iowa, made a notable mark during his 34 tenure with John Deere. He began his career in the drafting department, followed by designer positions in engine engineering. He served many other positions as well, including supervisor at Engine Works, project engineer, and most recently as the manager of marine and OEM project engineering.

Among his many accomplishments, Tom worked with the JDPS marine group in the development of the John Deere PowerTech marine engines, including the PowerTech 6.8L, 9.0L, 12.5L, and 13.5L engines.

“Tom was known for his expertise and had a passion for the marine engine market,” says co-worker Dave Flaherty. “His goal was to make

the marine engines the best they could be and to keep customers satisfied. He held strong to the core values of reliability, efficiency, simplicity, and engine longevity as we made marked improvements to the power density of our marine engine line.”

Outside of the office, Tom enjoyed visiting and talking with marine dealers and distributors, attending marine tradeshows, and boarding John Deere-powered boats when the opportunity was presented.

Throughout his career, Tom was recognized for his technical and professional abilities, as well as his commitment to mentoring young employees. His perseverance, perspective, and passion will be greatly missed.

The right formulaJohn Deere introduces the next generation of oils for marine engines

At John Deere, our engine technologies are advancing to meet current and future emissions regulations. Formulating engine oils to meet the needs of today’s engines is vital to their protection, performance, and longevity.

Keeping pace with the needs of today’s engine technologies, John Deere introduces the next generation of engine oil: Break-In Plus™ and Plus-50™ II.

Break-In Plus is a special-purpose engine oil developed for the initial break-in period of your new, remanufactured, or rebuilt engine. Plus-50 II carries on that protection for the rest of your engine life, enhancing performance and longevity.

“These two new oils are built upon the proven track record of our Plus-50 and Break-In oils, which are proven performers in the off-highway engine market,” says Sheri Barta, product line marketing manager for John Deere Merchandise.

When used with John Deere filters, both oils offer a maximum drain interval of up to 375 hours (see your John Deere dealer for details). This is a significant increase over other oil formulations. Compared to other oils on the market, Break-In Plus and Plus-50 II maintain their original viscosity longer and minimize oil breakdown. “This will save owners money and time on maintenance, all the while ensuring that their engines receive optimal protection,” says Sheri. (Refer to your operator’s manual for specific interval recommendations.)

John Deere-formulated oils provide the best protection and value for your engine. John Deere oils exceed the requirements of the American Petroleum Institute (API) Service Category CJ-4 for use in high-speed 4-stroke diesel engines. But we take our testing even a step further to John Deere’s very own JDQ-78X proving grounds. “The JDQ-78X is the most severe engine dynamometer test for high temperature oil oxidation in the industry,” says Dr. Ken Chao, engineer at Product Engineering Center in Waterloo, Iowa. “The proven performance from the JDQ-78X, along with extensive field testing, demonstrates that our oils provide the protection needed when load factor is higher and wear is more severe. They are also compatible with biodiesel blends such as B20.”

Our confidence in our oil products is reflected in our warranty. Break-In Plus and Plus-50 II are guaranteed to meet or exceed the oil requirements of your engine.

Look for John Deere engines at these upcoming tradeshows, conventions, and exhibits.

Build your own, design your own … Nowadays, we can design just about anything to reflect our personality — shoes, clothes, cell phones. And the boating industry is no different. At least for Dutch service-oriented shipyard ScheepsReparatie Friesland (SRF), which builds and restores craft completely to customer specs, completely in house. So their customers can roam the water in their own, personal style.

intensive but rewarding. The Phoenician, SRF’s most recent project, is a prime example of a customized craft. Previously a traditional steel workboat, it now serves as a luxury houseboat.

Restoration of the Phoenician was an intensive process requiring a meeting of the minds and mutual trust, according to Wychard Raadsman, owner of SRF. Wychard first explored ideas with the customer and then worked out design and refurbishments. “I love sharing that creative process with the customer and

working towards a unique goal,” he says with a smile. Regular visits to the shipyard showed the customer how the ideas were taking shape. “Occasionally we had to rethink original ideas because they didn’t work well or give the desired result,” explains Wychard.

practice makes perfect. After 1½ years of hard work, the 15.75-m (51.5 ft.) Phoenician is now touring the French inland waterways. Two trial runs with the John Deere 4045TFM engine have proved that this supposedly “light” engine is definitely up to the task. “I wasn’t convinced at first that it could drive the 15 kW (20 hp) rudder and run the craft smoothly,” says Wychard. “But a 6-cylinder was too bulky, so we agreed to give it a try — and it did the job.”

“A good return on investment” is how Wychard describes John Deere engines: “They have a durable engine block, and no bells and whistles that can break down. Spare parts are well-priced

driving innovation. Working closely with designers and customers results in some interesting innovations: the Phoenician boasts a telescopic spud pole that serves as an anchor. Unlike a traditional anchor, it keeps the craft in position without mooring ropes. An electric drive system, in combination with a small generator, allows the craft to “go green” for three hours at a continuous speed of 6 km/hr (3.7 mph).

In the meantime, Wychard has already embarked on his next challenge: refurbishing a 30-m luxury craft. “A John Deere 184-kW (247 hp) engine is definitely in the cards!” he concludes.

SRF works closely with designers and customers to create an optimal craft, like the Phoenician.

After evaluation, the PowerTech 4045TFM was found to be perfect for the job.

Characterized by its vibrant towns, colorful cuisine, and a crystalline coastline, the Mediterranean has many jewels in its crown. But for some visitors, the object of their desire offers something more. For one Russian sea and sailing enthusiast, the reliable Comet 100 by Comar Yachts is the ideal way to take on the waves and enjoy the tranquility. For him, this cruising sailboat is the jewel in the Mediterranean crown.

Going beneath the surface. For a complete sailing experience, the owner of the Comet 100 needed the best partners during the design of the boat. With a built-to-order philosophy, the interior was developed in partnership with award-winning Italian designers at Studio Vallicelli. All the carpentry and millwork was created by specialized Comar Yachts workshops. But to achieve total comfort, the answer is in the ride.

Comar Yachts is dedicated to building powerful and reliable sailboats, but their Comet 100 is a different breed. Identifiable by its pleasing aesthetic line, the Comet 100 measures 31 m (101.7 ft.) long, making it the biggest boat the company builds. A vessel this size requires an engine with high torque and agility to power the airex and fibreglass sandwich hull with little displacement. So, the manufacturers partnered with engine experts: John Deere engine distributor Rama Motori S.p.A and its local dealer Powerline S.r.l.

italian taste for perfection. For travelling long distances and taking time to discover the delights of the Mediterranean, the Comar Yachts team chose the PowerTech 6081AFM engine with high torque and great reliability. But also John Deere’s excellent service network and the proximity of Powerline S.r.l., located in Rome, were decisive factors. The Comet 100 is made to cruise, so readily available services throughout the Mediterranean are a must.

Working closely with Powerline S.r.l., Comar Yachts was impressed by the John Deere 6081AFM engine both technically and commercially. “It was a perfect fit for the design and no modifications were needed,” says Paolo Ceccarelli, general manager at Powerline. “Whether it’s weaving between sandy coves or powering through the surf, this high-performance sailboat found the engine it was looking for.”

Italian elegance and excellence are set to impress this lucky Russian owner before the vessel’s expected launch date in July 2011. Looking ahead, a new Comet 100 is on the horizon for another seafaring aficionado. Due to a successful partnership, John Deere is positioned to power the new yacht and take to the sea once again.

The key to any successful business is maintaining a steady customer base, so flexibility, personal care, and clear communication are essential. A touch of creativity doesn’t hurt, either. Altena Yachting B.V. understands this only too well. Since 1969, this family-run company has helped customers create their personalized dream yachts with good sailing qualities and all the comforts of home. And some homes are very comfortable! That’s why customers come back again and again.

delivering on promises. A customer from Luxemburg bought his first Altena craft, a 15.5-m (51 ft.) Altena Blue Water Trawler, in 2002. A John Deere 6068DFM engine with a Twin Disc MG 5011A transmission ensured smooth sailing around Palma de Mallorca.

Five years later, he decided on a larger craft, something even more comfortable. To find the one that would meet all his desires, he returned to Altena. The 18.5-m (61 ft.) Altena Explorer was fitted out to the customer’s specifications, with a spacious saloon, teak interior and hydraulic bow/stern thruster stabilizers. This time, a John Deere PowerTech 6081AFM engine was selected for main propulsion and for powering the hydraulic bow thruster.

Now, the customer is again ready to move up. He is discussing the purchase of a third Altena yacht: a 24-m (78.7 ft.) craft. His Altena Explorer is looking for a new owner, and with its high resale value, it is expected not to be on the market for long. The new yacht will also be tailored to his high standards and precise specifications. “Altena is open to my requirements, and they deliver on their promises,” the customer says. “That’s why I keep coming back.”

Altena’s range of cruisers caters to both the relaxed and the more adventurous sailor. The Excel, Family, and Canal Cruisers are ideal for leisure sailing in inland waters, while the Coastal Cruisers and Blue Water, Explorer, and Custom Trawlers are outstanding in open sea and rough sea. The steel and aluminum craft vary in length from 11 to 20 m (36 to 65.5 ft.).

loyalty extends to John deere. For this new yacht, it’s not surprising that Marcel Pols, Altena Yachting director, will again recommend a John Deere engine. Altena has been using John Deere engines for 17 years and is a true advocate of the brand. “Back in 1993, hydraulic attachments were becoming popular, and most engine brands simply couldn’t handle them,” explains Marcel. “A customer suggested John Deere; he knew their engines were reliable in agricultural applications.”

Since then, Altena has powered some 50 craft with John Deere engines, ranging from 100 kW (134 hp) to 205 kW (275 hp). “On our larger, ocean-going craft, we always install John Deere PowerTech 6081AFM engines. Customers never question this choice; they know they need a solid, reliable engine that can handle tough weather conditions,” comments Marcel.

Because John Deere engines keep on running, Altena hasn’t had much need for John Deere engine distributor Nagel Power Systems. “But when we do need them, they deliver on their promises, just as we do!”

PowerSource is pleased to feature an interview with Jean Pierre and Marie Dufour. Jean Pierre, a retired family practitioner, and Marie Dufour, a retired nutritionist, are owners of a new twin-engine catamaran they call Domino. After rearing their five children, the couple built the 20-m (66 ft.) motorcat passagemaker to cruise the oceans of the world and provide health and nutrition services to the most isolated islands of the South Pacific. In this article, the Dufours share their goals and travel experiences since the launch of this new John Deere-powered vessel in December 2009 in Asuncion, Paraguay.

powersource: What are some of the reasons why you decided to build the Domino?

Jean pierre: Our goal is to provide health missions to the most isolated islands of the South Pacific in coordination with the World Health Organization. Domino was designed and built to cruise and work in the South Pacific. We wanted a two-person liveaboard catamaran capable of cruising any ocean at a reasonable speed, with comfort, great reliability, and autonomy. We asked renowned catamaran designer Malcom Tennant to apply his lifetime experience in catamaran design, and he came up with the cruising machine called Domino.

powersource: What were some of your design goals for the Domino?

Marie: The boat had to be easily handled by only two people who were not professional mariners. We chose a motor catamaran over a monohull because we find cats more spacious. The cabin is arranged on one level: head, stateroom, galley, salon and pilothouse are all en-suite. This gives a very open feeling to the entire boat. With 25 windows, we have a full 360º view of our surroundings. It’s quite lovely!

Jean pierre: The boat had to be as reliable as possible, especially propulsion and anchoring. Function came first. Our John Deere engines had to perform to perfection and we have been able to get service whenever and wherever we needed it, the world over. Safety at anchor is assured with our two Ancora Latina anchors and a massive anchor windlass. A redundant electrical system and our ability to run our HRO watermaker, making 250 l (66 gal.) of fresh water per hour, meant autonomy on the open water.

Jean pierre: The engine powers the hydraulic steering. Alternators fitted on each engine

powersource: The Domino was built in Paraguay, and for the next several months, you cruised up the coast of Brazil toward the Caribbean. What was that like?

Marie: Cruising Brazil was an intense experience, not only because this was Domino’s maiden voyage but also because Brazil offers such a wide variety of cruising conditions. Quiet lagoons and treacherous reefs, secure island coves, and wild river currents, and—of course—the fearsome Amazon! We took advantage of the variety of sea conditions to fully test Domino.

powersource: How did she do?

Marie: Cruising the Bahia de Todos los Santos (Salvador) at 25 knots, standing on the foredeck and holding on to nothing else but my hat was a testimony to Domino’s stability and sea-keeping ability.

Jean pierre: Coming up the southern coast of Brazil, with 20 knots of wind and a strong current on our nose, Domino was happy cruising at 12 knots without excessive slamming or twisting. She just ‘sambas’ into the waves.

powersource: What are some of your most exciting or most memorable experiences on your trip so far?

Jean pierre: Entering Rio de Janeiro and anchoring in Guanabara Bay, with the Sugar Loaf on starboard and the Christ Redemptor on port. It’s quite impressive.

Marie: Anchoring off of the scarcely populated islands of Ilha George Grego by Ilha Grande, the Abrolhos Archipelago, or off of the Salvation Islands in French Guyana. Counting on the reliability of our engines and anchors allows us to get into remote anchorages.

powersource: How did you come about powering Domino with John Deere engines?

Jean pierre: We had read great reviews, especially one article in PassageMaker magazine a few years ago.

powersource: What engine characteristics topped your wish list?

Jean pierre: We wanted an engine that was quiet, reliable, with easy maintenance and worldwide service. We also wanted engines that would fit in the narrow space of Domino’s hulls, which were 1.20 m (4 ft.) at the widest point. Because of the difficulty it would be to remove the engine, we wanted an engine that can be rebuilt on site. The winning point was the fact that the John Deere engine’s cylinder liners are removable, as they are not part of the engine block. This makes major repairs, if needed, easier and cheaper than with other engines.

powersource: Now that you are well into your travels, how are the John Deere engines performing?

Jean pierre: Domino is an incredible cruising machine. The PowerTech 6081AFM delivers 224 kW (300 hp) per engine. The M2 rating allows us to run the engine for days on end. She loves to ride at 20 knots. The hum of the engine is pleasant, and at 20 knots at 2000 rpm, we do not have to raise our voice to be heard in the pilot room. But, most of the time we cruise at 12 knots, barely hearing the engine and

The high pressure rail system makes this a very quiet engine with high torque at low rpm to turn our large 34 in. (86 cm) props. In addition to being quiet, reliable, and fuel efficient, these engines are really easy to service. Also, there is no smell of diesel fumes anywhere around this boat!

powersource: What is the combined fuel consumption of the John Deere engines?

Jean pierre: Running 20 knots at 2000 rpm, we’re getting 26 gph. At 12 knots at 1300 rpm, that lowers the fuel consumption to just 9 gph (98 l/hr).

Marie: Overall, since we launched, and over 8,000 nautical miles, we’ve averaged a 13.5-knot speed and one mile per gallon.

powersource: Describe your experiences with John Deere engine specialists along the way.

Jean pierre: We first made contact with our John Deere engine distributor, Don Freeman of Bell Power Systems. But very quickly we dealt with Jobi Javellana, the head of South America’s operations, who guided us through our travels and referred us first to the fabulous Team Argentina in Rosario, then to Team Recife in Brazil, and now to Trintrac and Richard Blanc in Trinidad. Whatever our need, John Deere South America has been wonderfully responsive and has catered to us.

powersource: So your John Deere engine distributor got you in touch with the right people in Argentina?

Jean pierre: Alerted by Don Freeman, the entire John Deere Argentina took us under their wing when we reached Rosario (Argentina) and ran all our sea trials on the Rio Parana. Engineers Alberto Souto and Jose Echeverria let their service manager Eng. Dario Matijacevich run Domino through her paces. So we send big kudos to Don Freeman who never let us down and referred us to the John Deere division most able to help us, wherever we were.

Marie: I keep raving about the John Deere service and personal touch. Over the last four years, we’ve dealt with hundreds of brands and industries. Few have been as wonderful and responsive as John Deere.

powersource: What do you like most about your boating adventures?

Jean pierre: We enjoy being at sea. We like the challenge of crossings, the tranquility of being away from shore and the now-familiar rocking of the boat. We also enjoy the social life and interaction with other cruisers. It is a small community, and at every port we meet wonderful people. We share our adventures, difficulties, talk about the next port, play music, and sing folk songs in group — quite a change from the daily hassles and stresses of running a medical practice!

powersource: So where are you and the Domino headed in 2011?

Marie: We are now making our way up the Eastern Caribbean. Domino is our home, our work platform, our passion, and we love to see so many other people catching the Domino fever and making sure that we make her one unique, performing cruising machine!

Boat owners wanting a keel-cooled version of the popular 9.0L marine engine will take great interest in a new John Deere marine engine that will hit the water in 2011.

Make way for the PowerTech 6090AFM75 — a welcome addition to a great lineup of John Deere marine engines ranging from 213 to 317 kW (285 to 425 hp).

“The new 9.0L engine replaces the PowerTech 6081AFM keel-cooled marine engine and is an excellent choice for recreational trawler yachts, commercial vessels, and generator drive engines,” says Dave Flaherty, marine marketing manager for John Deere Power Systems.

The new 9.0L engine packs more horsepower per liter of displacement. With 317 kW (425 hp) at 2400 rpm, the PowerTech 6090AFM delivers 37 kW (50 hp) more than the 8.1L engine at the highest propulsion rating. Gen-sets will reap an additional 25 kW of power both at 50 and 60 Hz.

The new PowerTech 6090AFM is a keel-cooled version of the well-established seawater-cooled John Deere PowerTech 6090SFM engine — a marine engine that has proven itself time and time again in countless recreational marine applications across the globe.

“John Deere continues to expand the marine engine lineup with new models and higher horsepower ratings,” says Dave. “We designed the new 6090AFM75 to provide high power output from a compact engine while maintaining the legendary long-term reliability our customers have come to expect from John Deere marine engines.”

There’s something about crystal clear turquoise blue waters and pearly white sandy beaches that seem to tug at Captain Gerry Cooper’s wanderlust these days.

It all started when he repowered his 14.6-m (48 ft.) custom trawler with a new PowerTech 6135SFM engine. Gerry’s aquatic world seemed to reopen, and he soon found himself frolicking in the beautiful Bahama Islands, a tropical archipelago of over 700 islands in the Atlantic Ocean southeast of Florida.

“After I got the new John Deere engine in November 2009, I took my first trip to the Bahamas. Now I’m hooked … I really am,” says Gerry, who moors the Roncador in St. Petersburg, Florida.

The Roncador is a longtime travel companion for Gerry, who purchased the Marine Management vessel in 1979. Designed by Jim Wynne and built by Lee and Jo Anne Brooks, the vessel features a sturdy, heavy-duty hull, and for many years, it served as a multipurpose charter boat. “Now it’s strictly for pleasure,” he says. “I’ve been to a lot of places with it, including the Panama Canal. I’m sentimental about the boat.”

Three decades of traveling took a toll on the Roncador’s original engine, and over time, the vessel became less suited for travel into pristine marine environments. “The original engine became a problem,” relates Gerry. “It got to the point that I could no longer go into most marinas because of the smoke and oily discharge in the water.”

Ready for a repower, Gerry was given the opportunity to install a prototype PowerTech 6135SFM — John Deere’s largest displacement engine with seawater aftercooling. “It’s a single-engine boat, so I wanted a reliable engine,” says Gerry. “I admit that I initially dreaded the thought of a repower, thinking it would be a chore, but it wasn’t. I quickly became comfortable with the skill level of my John Deere marine dealer and his expertise in installing the engine, and that added to my confidence in the John Deere engine and its reliability.”

Not only is the Roncador more reliable, she’s easier on fuel, too. “The fuel consumption of this 500-hp (373-kW) engine is really remarkable,” says Gerry. “I’m using just one-third of the fuel that I used to burn running the 356-hp (266-kW) engine.”

The new PowerTech 6135SFM turns a 26x28-inch (66x71 cm), four-blade prop through a Twin Disc transmission with a 2.5:1 gear ratio. The fiberglass hull features a semi-enclosed tunnel that directs water to the prop, enhancing the 14.5-t (16 US t) trawler’s ability to achieve an impressive top speed of 18 knots at 1950 rpm, “which is handy,” he says, “especially if you need to outrun weather.”

Gerry typically enjoys a cruiser’s pace, and he found Roncador’s sweet spot running 7.5 knots at 900 rpm. That’s where the PowerTech 6135SFM consumes just 9.5 l/hr (2.5 gph) of fuel. Gerry calculates that to be a miserly 1.5 l/nautical mile (.33 gallons per nautical mile). As a result, he’s more than doubled his boat’s range.

More range means more quality, uninterrupted cruising around those beautiful Bahamian Islands. Plus, Gerry no longer worries that his engine may be spoiling the pristine environment. In fact, Gerry says the newly repowered Roncador is a traveling testimony for the new PowerTech 6135SFM. “People are seeing the future (of emissions), and they are seeing my enthusiasm about the engine,” he says. “Seeing is believing.”

The PowerTech 6135SFM is carefully lowered for installation.

The Roncador keeps pristine waters clean thanks to its new PowerTech 6135SFM engine, which drives a 26x28-in. (66x71 cm), four-blade prop.

Gerry Cooper finds himself lured to the beauty of the Bahama Islands with his longtime travel companion, the Roncador.

The Alaska Quest was repowered with a new PowerTech 6081AFM marine diesel just months before the rescue.

It’s a rare event that a John Deere marine engine would assist in a rescue of wild deer, but that’s exactly what happened at Taku Inlet, Alaska, this past fall.

Tom Satre and his family were cruising aboard the Alaska Quest when they spotted four black-tail deer swimming toward their 19-m (62 ft.) charter boat.

Were the deer lured to the smooth call of the PowerTech 6081AFM marine engine? Not likely. The cold and tired deer were about 2 km

(1.2 mi.) from shore and just minutes away from drowning, looking for a desperate escape from the frigid water.

“They swam right toward the boat,” he said. “They were swimming in 2-ft. (60 cm) chop, unable to see over the waves. They were circling the boat and looking as if saying ‘help us, help us.’”

Tom knew something had to be done and did some fast thinking to get them onboard. “I formed a lasso with the mooring line and dropped it around their heads one at a time,” relates Tom. “They were about 85 pounds (39 kg), sopping wet. We were fortunate to have a low swim step at the stern, and I was able to pull them onboard. If we had to haul them over the side, I couldn’t have done it.”

Putting their wild, skittish instincts aside, the deer willingly came onboard and collapsed, too tired to even shake off the water. “They were absolutely gassed,” he recalls. “The last one was in really poor shape. He was very hypothermic. I massaged him for 20 minutes trying to warm him up. He bleated like a little lamb. I think he was appreciative.”

The Alaska Quest headed to Taku Harbor, and during the hour-long ride, one deer stood up. When the Alaska Quest arrived to harbor, the deer hopped onto the dock, looked back, then leapt into the waters of the harbor, swam to shore, and quickly disappeared into the forest. Two others followed suit, after a bit of prodding and assistance from the group. The last one had to be wheel-barrowed off the boat. Tom says all four deer survived the ordeal.

Although the event was unusual, it almost seems fitting for the Alaska Quest to be involved in that sort of mission. The vessel spends many cruising days giving eco-tours in southeast Alaska to view whales, porpoise, and bears. Swimming deer are more of a rarity.

Cold and tired, four tired young bucks approach the Alaskan Quest, looking to escape the water.

Tom Satre used his mooring line to lasso the deer and pull them on deck. The four deer lay exhausted aboard the Alaska Quest after being pulled from water.

With an appreciation for the environment, Tom chose to upgrade his vessel with a new a low-emissions, fuel-efficient PowerTech 6081AFM marine engine last spring. The new engine was purchased and installed by Mark Jochems of Shoreline Marine Diesel Inc. in Port Townsend, Washington. Mark paired the 224-kW (300 hp) engine to a Twin Disc transmission with a 3:1 gear ratio. The engine turns a 36x31-inch (91x79 cm) prop and consumes just 18.5 l/h (4.9 gph) at 8.7 knots at 1600 rpm.

“That’s phenomenal for a 60-ton (54 mt) boat,” says Tom of the steel-hull, full-displacement vessel. “The engine is phenomenally powerful. It has all of the power and torque I need. If I ask for 2200 rpm, I get it immediately.”

A love for Alaska and a passion for the environment, Tom and his wife, Tish, enjoy sharing their enthusiasm with others aboard the Alaska Quest.

“What we do is go out and see if clients can have as much fun as we’re having,” says Tom. “We get to show them what we love, and that’s Alaska. And it’s not just the beauty that they love, it’s the people who reside there, too.

“The people are pretty special here,” says Tom. “They’re willing to lend you a hand when you are in trouble.”

Certainly the four rescued deer could only agree.

Jim Seyler loves the smell of salt air.

Native to the Pacific Northwest, Jim has spent his life around the water, whether it was hanging out at the commercial fishing docks with his grandfather as a child or working his way through college aboard an ocean-going tugboat.

Today, Jim’s career as a financial consultant doesn’t stop him from having a piece of this past. He enjoys living on the water. In fact, his home literally floats on the banks of the Columbia River. Rather than a front yard, water flows like an avenue of escape from a long day of market analysis. And with just a punch of a garage button, Jim and his wife, Sandy, can board their 9.8-m (32 ft.) Grand Banks yacht and enjoy immediate retreat from a hard day’s work.

Jim says it was the classic style of the 1971 wooden Grand Banks trawler that caught his eye four years ago. “The boat was reminiscent to my grandfather’s 42-ft. (13 m) wooden salmon trawler,” recalls Jim. “I like an all-wood boat. I also prefer diesel motors.”

Jim also loves the thought of more extended trips into the ocean blue. When Jim and Sandy purchased the Grand Banks, it was in near-immaculate condition, yet they knew the 40-year-old engine would eventually need to be either rebuilt or replaced, especially if he’d ever venture much beyond Columbia’s riverbanks.

“It came down to these choices: rebuild it and still have old technology; replace it with a near identical twin; or step up to modern technology,” relates Jim of his decision. “It didn’t take me long to believe that it was the John Deere engine that I wanted.”

Running on reliabilityAn engine repower turns a classic trawler into an ocean-bound cruiser

The 9.8-m (32 ft.) Grand Banks moors in the garage next to the floating home on the Columbia River.

A new PowerTech 4045TFM engine offers more power and space in the engine room.

13PowerSource

Jim contacted Multnomah Yacht Repair, a full-service boat yard and John Deere marine engine dealer, and there he purchased a new fully electronic PowerTech 4045TFM engine.

“I wanted an engine that would last as long as the boat — an engine that was state-of-the-art, proven, and low maintenance,” states Jim. “And this engine met that criteria.”

Removing the old 6-cylinder engine proved to be a “monster job.” Jim hired Independent Marine Repair to perform the repower in Scappoose, Oregon. With attention to detail, Jim had the engine and all of the vessel’s electrical wiring replaced.

Today, the engine room boasts a whole new look. The PowerTech 4045TFM, with its smaller displacement and footprint, gives much more space to the engine room. The engine is lighter and more powerful, too.

“The throttle is very responsive, she runs smoother and much quieter, and starts with the push of a button. And, there’s no smoke. I’m very pleased with the result.”

Although the new engine is also more fuel efficient, that’s not one of Jim’s priorities. It is the reliability and longevity of the John Deere engine that matters to him the most.

“Mechanically what I have now is very solid,” says Jim. “I am now comfortable taking this boat out into the Pacific Ocean, heading north to the San Juan Islands, and further up in the Inland Passage to Alaska. From a mechanical standpoint, I wanted an engine that was reliable — an engine I can trust. Weather permitting, now we can travel the oceans with confidence, knowing we have one of the most reliable diesel engines money can buy.”

Jim Seyler and his wife will enjoy extended cruises into the Pacific Northwest aboard the repowered Grand Banks.

A year ago, Jim repowered the 11-m (36 ft.) Dream Weaver with a new PowerTech 4045TFM marine engine. Certainly it was time, he admits. The old two-cycle engine developed some bad habits over the years. It smoked badly, leaked oil, and rudely drowned out his conversations.

“Everybody would be enjoying a quiet summer morning drinking coffee, and we would start up to leave, and a big cloud of smoke would come out, and the loud noise would echo off the cliffs,” recalls Jim. “It was just nasty.” He also spent too much time in the

engine hatch checking oil levels. “People would joke saying ‘If your engine quits leaking oil, you better put more oil in it.’”

Ready to remove the old 2-cycle engine, Jim sought the advice of Wayne Gregg of Gregg’s Diesel, who suggested that Jim install a new 101-kW (135 hp) PowerTech 4045TFM engine. The repower included removing the old Twin Disc crash box and replacing it with a new Twin Disc 5011 transmission with a trolling valve. Using a 2.5:1 gear ratio, the transmission mounts to a 44-mm (1.75 in.) shaft that turns a 25x20 in. (635x508 mm), 3-blade propeller.

is this a dream? Now Jim peers into his engine compartment in near disbelief. Not only is the engine compartment clean, the new 4-cylinder engine measures almost a half a meter (20 in.) shorter than the old 6-cylinder block. His wheelhouse has a whole new look, too. A single electronic monitor displays all of his onboard functions.

The Dream Weaver will soon be Alaska bound with her new John Deere marine engine.

Jim Bass is ready to head north on his newly repowered 1961 Dream Weaver.

He particularly likes his newfound ability to electronically monitor and set the engine rpm to maximize fuel efficiency — something he was unable to do with his old engine. “There’s no more guesswork,” says Jim. “I know how much fuel I’m using per hour, and that’s neat.”

To maximize fuel economy, Jim runs 8 knots at 2100 rpm. At that speed, the 13.6-t (15 US t) Dream Weaver consumes 13 l/hr (3.5 gph) — a notable improvement over the old 123-kW (165 hp) engine that burned roughly 19 l/hr (5 gph) running at 1400 rpm.

It’s made the Dream Weaver more enjoyable in other ways, too. “You hit the button, and it starts right up,” says Jim. “And now we can actually hear the water when we’re cruising along.”

Jim admits to “dragging his feet” on the repower, over concern of converting to an electronically controlled marine engine. “But the John Deere engine proved me wrong,” says Jim. “It’s pretty darn reliable, and it’s made the boat more of a pleasure to take out. I’m tickled to death with it.”

When Richard Armstrong of Westport, Massachusetts, powers up his 21-m (70 ft.) Little Vigilant, an element of maritime history goes along for the ride.

Built in 1950 by Abeking and Rasmussen of Bremerhaven, Germany, the Little Vigilant is a custom motorsailer whose lineage traces to the Vigilant, a 30-m (100 ft.) sardine carrier-style vessel built in the 1930s by wealthy yachtsman Drayton Cochran of New York. When the Vigilant was rundown in the WWII war effort, Cochran had a smaller version of his vessel built. Designed by Walter McGinnis of Boston, the 30-m (70 ft.) Little Vigilant features a fold-down rig and a removable wheelhouse so that she could easily transit the canals of Europe during the Cochrans’ travels abroad.

The Little Vigilant spent a leisurely decade plying the inland waterways there, and was eventually sold and stored in Poole, England. There she sat for nearly a half century; that is, until Richard Armstrong came along.

“I have always loved sardine carriers,” says Richard. “They are seaworthy, easy to navigate, and perfect in looks.”

When Richard purchased the Little Vigilant, he cut no corners to restore those good looks. Renovated by Fairhaven Shipyard in Fairhaven, Massachusetts, the Little Vigilant received a complete makeover with paint and varnish. Richard also commissioned Nor’ east Marine Systems of Fairhaven to replace every pipe and wire. “I wanted to install all new systems — plumbing, wiring, refrigeration, navigation, heating, air conditioning — yet, I wanted to keep the interior original and true to her owners’ and designer’s original wishes,” relates Richard.

Richard also wanted a reliable, long-running engine that would power the Little Vigilant well into the future. “I was looking for a slow-turning, 4-cycle engine with an M1 or M2 rating,” says Richard. Researching engines, Richard found that John Deere engines are the power of choice for many friends who fished in Maine, as well as several high-end long-distance trawler manufactures, including Nordhavn, Grand Banks, and Kadey Krogen.

“Everything just pointed to John Deere,” Richard recalls. That’s when he contacted John Deere engine distributor Bell Power Systems and marine dealer R.A. Mitchell, and decided that he couldn’t steer wrong with a new PowerTech 6081AFM. “We sized it, did all of our calculations and propulsion data, and decided it was a perfect engine for the boat.”

Richard purchased the engine and hired Fairhaven Shipyard to install it. The 175-kW (235 hp) engine was paired to a Twin Disc transmission with a 3.33:1 gear ratio and fitted the shaft with a 38x30-in. (965x762 mm), 4-blade prop with a right-hand rotation.

“I’m extremely happy with the new engine,” relates Richard. “I really love it. The engine is great, and it’s twice the horsepower of my old engine, yet it’s quiet. We cruise 9.8 knots at 1650 rpm, and the engine uses only 43 percent of its power. And the electronically controlled fuel system on the John Deere engine is fantastic,” he adds. The Little Vigilant consumes a modest 25 l/hr (6.5 gph) at 1650 rpm. Richard calculates a long-distance range of 9,656 km (6,000 mi.) with 6814 l (1,800 gal.) of onboard fuel at lower rpm ranges.

That range makes the Little Vigilant prepared for some future blue water passages. “I do desire to travel into the Baltic and Mediterranean seas and the British Islands,” says Richard.

Restored and repowered, the Little Vigilant will surely take him there, and well into the future.

As the cold winter winds blow, we can only dream of summer in the south of France. But when the sunny weather comes, so do the sunbathers, packing the beaches “like sardines,” says Jean-Pierre Pradié of Toulon, France. He and his wife, Annie, escape the crowds and enjoy true far niente (pleasant idleness) on the Ceres, their 12.8-m (42-ft.) Grand Banks yacht. “We just head into the Mediterranean and find pure tranquility,” he comments.

a room with a view. The couple bought the Ceres, originally built in 1977 in Singapore, in 2000 from a neighbor. “It was really run down, and he fixed it up nicely,” recalls Mr. Pradié. “Now it’s very comfortable! Two cabins, including a large master cabin, a bath, a shower, and a dining room. And the 360º views from below are wonderful!”

original power. While the boat had been refurbished before the Pradiés bought it, the engines hadn’t been touched. The Ceres was, and still is, powered by its original John Deere 6404 engines. “I didn’t have to do anything to the engines themselves,” explains Jean-Pierre. To get the boat back to cruising condition, he replaced the starters,

the injectors, the feed pumps, and the water pumps. “I think that was only to be expected for a 30-year-old boat,” he says with a smile.

After 10 years of smooth sailing, the engines — now running for over 30 years — are still going strong. “They have about 3,300 hours on them, and we run them for 100 hours per year,” he explains. “We don’t have to sail far to get away from the crowds: we can get to Corsica in about 15 hours, going 16 km/hr (10 mph), for example. Or we can reach Elba in 20 hours. We’re not in a hurry. The islands will be there when we arrive!”

Fuel consumption remains very good. “At 16 km/hr (10 mph), I use only 14 l/hr (3.70 U.S. gph) for the two engines. That suits me perfectly. I don’t need to go 20 km/hr (12.4 mph), to save 45 minutes.”

Good parts and proper maintenance. For getting the Ceres into tiptop shape, Jean-Pierre appreciated the help of John Deere distributor Jeryh Trehel of Silenc’Air. “I knew about engines from working on sailboats I previously owned, but I’m not a specialist. Jeryh Trehel is a very good mechanic, and helped me find the parts I needed, which wasn’t always easy. Together, we keep the boat — and engines — afloat.”

Keep in mind that the exact spare parts you need really depends on the model of your John Deere engine and the extent of your travels. “What may be essential for cruisers of the Intercoastal Waterway may be different than for a passagemaker,” advises Joby Javellana, John Deere regional sales manager. “So consult your local John Deere marine dealer for a recommended list of parts for your specific engine and travel plans.”

Know your engine. “You owe it to yourself to become familiar with your engine, not only for the sake of gaining knowledge or conducting routine service, but also to perform repairs in mid-voyage, if necessary. Your John Deere operation and maintenance manual can be a wealth of information in times of need,” says Joby. Also, the John Deere Parts and Service Directory is your resource for locating a John Deere distributor or marine dealer during your travels.

Also, make sure to register your engine warranty, advises Matt Dewey, product manager of parts marketing for John Deere Power Systems. If your marine engine is registered, it streamlines the entire process if you have a warranty situation. So if you haven’t done so already, it’s easy to register by contacting your local John Deere distributor or service dealer. If you are in North America, you may also go to www.JohnDeere.com/warranty and click on “Warranty Registrations.”

Finally, you can count on genuine John Deere maintenance products to give you the best quality and value. Genuine John Deere replacement parts and products are specifically designed and engineered by John Deere for John Deere engines, says Matt. “Our parts restore the original quality and performance of your marine engines so that you can enjoy the journey with peace of mind.”

Visit your local John Deere marine dealer for a specific list of recommended parts for your vessel, engine model, and travel plans.

John Deere is sad to announce the passing of a very important team member of John Deere Power Systems (JDPS).

Tom Lekar of Waterloo, Iowa, made a notable mark during his 34 tenure with John Deere. He began his career in the drafting department, followed by designer positions in engine engineering. He served many other positions as well, including supervisor at Engine Works, project engineer, and most recently as the manager of marine and OEM project engineering.

Among his many accomplishments, Tom worked with the JDPS marine group in the development of the John Deere PowerTech marine engines, including the PowerTech 6.8L, 9.0L, 12.5L, and 13.5L engines.

“Tom was known for his expertise and had a passion for the marine engine market,” says co-worker Dave Flaherty. “His goal was to make

the marine engines the best they could be and to keep customers satisfied. He held strong to the core values of reliability, efficiency, simplicity, and engine longevity as we made marked improvements to the power density of our marine engine line.”

Outside of the office, Tom enjoyed visiting and talking with marine dealers and distributors, attending marine tradeshows, and boarding John Deere-powered boats when the opportunity was presented.

Throughout his career, Tom was recognized for his technical and professional abilities, as well as his commitment to mentoring young employees. His perseverance, perspective, and passion will be greatly missed.

The right formulaJohn Deere introduces the next generation of oils for marine engines

At John Deere, our engine technologies are advancing to meet current and future emissions regulations. Formulating engine oils to meet the needs of today’s engines is vital to their protection, performance, and longevity.

Keeping pace with the needs of today’s engine technologies, John Deere introduces the next generation of engine oil: Break-In Plus™ and Plus-50™ II.

Break-In Plus is a special-purpose engine oil developed for the initial break-in period of your new, remanufactured, or rebuilt engine. Plus-50 II carries on that protection for the rest of your engine life, enhancing performance and longevity.

“These two new oils are built upon the proven track record of our Plus-50 and Break-In oils, which are proven performers in the off-highway engine market,” says Sheri Barta, product line marketing manager for John Deere Merchandise.

When used with John Deere filters, both oils offer a maximum drain interval of up to 375 hours (see your John Deere dealer for details). This is a significant increase over other oil formulations. Compared to other oils on the market, Break-In Plus and Plus-50 II maintain their original viscosity longer and minimize oil breakdown. “This will save owners money and time on maintenance, all the while ensuring that their engines receive optimal protection,” says Sheri. (Refer to your operator’s manual for specific interval recommendations.)

John Deere-formulated oils provide the best protection and value for your engine. John Deere oils exceed the requirements of the American Petroleum Institute (API) Service Category CJ-4 for use in high-speed 4-stroke diesel engines. But we take our testing even a step further to John Deere’s very own JDQ-78X proving grounds. “The JDQ-78X is the most severe engine dynamometer test for high temperature oil oxidation in the industry,” says Dr. Ken Chao, engineer at Product Engineering Center in Waterloo, Iowa. “The proven performance from the JDQ-78X, along with extensive field testing, demonstrates that our oils provide the protection needed when load factor is higher and wear is more severe. They are also compatible with biodiesel blends such as B20.”

Our confidence in our oil products is reflected in our warranty. Break-In Plus and Plus-50 II are guaranteed to meet or exceed the oil requirements of your engine.

Look for John Deere engines at these upcoming tradeshows, conventions, and exhibits.
