Safety informationEMU33622

Outboard motor safetyObserve these precautions at all times.EMU36501

PropellerPeople can be injured or killed if they come incontact with the propeller. The propeller cankeep moving even when the motor is in neu-tral, and sharp edges of the propeller can cuteven when stationary.� Stop the engine when a person is in the wa-

ter near you.� Keep people out of reach of the propeller,

even when the engine is off.EMU40271

Rotating partsHands, feet, hair, jewelry, clothing, personalflotation device (PFD) straps, etc., can be-come entangled with internal rotating parts ofthe engine, resulting in serious injury or death.Keep the top cowling in place whenever pos-sible. Do not remove or replace the top cowl-ing with the engine running.Only operate the engine with the top cowlingremoved according to the specific instructionsin the manual. Keep hands, feet, hair, jewelry,clothing, PFD straps, etc., away from any ex-posed moving parts.EMU33640

Hot partsDuring and after operation, engine parts arehot enough to cause burns. Avoid touchingany parts under the top cowling until the en-gine has cooled.EMU33650

Electric shockDo not touch any electrical parts while startingor operating the engine. They can causeshock or electrocution.EMU40861

Power trim and tiltBody parts can be crushed between the out-board motor and the clamp bracket when theoutboard motor is trimmed or tilted. Keep

body parts out of this area at all times. Makesure that no one is in this area before operat-ing the power trim and tilt mechanism.The power trim and tilt switches operate evenwhen the main switch is turned to the “ ”(off) position. Keep people away from thepower trim and tilt switches whenever workingaround the outboard motor.Never get under the outboard motor while it istilted, even when the tilt support shaft is in-stalled. Severe injury could occur if the out-board motor accidentally falls.EMU41251

Engine shut-off cord (lanyard)Attach the engine shut-off cord so that the en-gine stops if the operator falls overboard orleaves the helm. This prevents the boat fromrunning away under power and leaving peo-ple stranded, or running over people or ob-jects.Always attach the engine shut-off cord to asecure place on your clothing or your arm orleg while operating. Do not remove it to leavethe helm while the boat is moving. Do not at-tach the engine shut-off cord to clothing thatcould tear loose, or route the engine shut-offcord where it could become entangled, pre-venting it from functioning.Do not route the engine shut-off cord where itis likely to be accidentally pulled out. If the en-gine shut-off cord is pulled during operation,the engine will shut off and you will lose moststeering control. The boat could slow rapidly,throwing people and objects forward.EMU33810

GasolineGasoline and its vapors are highly flam-mable and explosive. Always, refuel accord-ing to the procedure on page 54 to reduce therisk of fire and explosion.

EMU33820

Gasoline exposure and spillsTake care not to spill gasoline. If gasolinespills, wipe it up immediately with dry rags.Dispose of rags properly.If any gasoline spills onto your skin, immedi-ately wash with soap and water. Changeclothing if gasoline spills on it.If you swallow gasoline, inhale a lot of gaso-line vapor, or get gasoline in your eyes, getimmediate medical attention. Never siphonfuel by mouth.EMU33900

Carbon monoxideThis product emits exhaust gases which con-tain carbon monoxide, a colorless, odorlessgas which may cause brain damage or deathwhen inhaled. Symptoms include nausea,dizziness, and drowsiness. Keep cockpit andcabin areas well ventilated. Avoid blocking ex-haust outlets.EMU33780

ModificationsDo not attempt to modify this outboard motor.Modifications to your outboard motor may re-duce safety and reliability, and render the out-board unsafe or illegal to use.EMU33740

Boating safetyThis section includes a few of the many im-portant safety precautions that you should fol-low when boating.EMU33710

Alcohol and drugsNever operate after drinking alcohol or takingdrugs. Intoxication is one of the most commonfactors contributing to boating fatalities.EMU40280

Personal flotation devices (PFDs)Have an approved PFD on board for every oc-cupant. Yamaha recommends that you mustwear a PFD whenever boating. At a minimum,children and non-swimmers should always

wear PFDs, and everyone should wear PFDswhen there are potentially hazardous boatingconditions.EMU33731

People in the waterAlways watch carefully for people in the wa-ter, such as swimmers, skiers, or divers,whenever the engine is running. When some-one is in the water near the boat, shift intoneutral and stop the engine.Stay away from swimming areas. Swimmerscan be hard to see.The propeller can keep moving even whenthe motor is in neutral. Stop the engine whena person is in the water near you.EMU33751

PassengersConsult your boat manufacturer’s instructionsfor details about appropriate passenger loca-tions in your boat and be sure all passengersare positioned properly before acceleratingand when operating above an idle speed.Standing or sitting in non-designated loca-tions may result in being thrown either over-board or within the boat due to waves, wakes,or sudden changes in speed or direction.Even when people are positioned properly,alert your passengers if you must make anyunusual maneuver. Always avoid jumpingwaves or wakes.EMU33760

OverloadingDo not overload the boat. Consult the boat ca-pacity plate or boat manufacturer for maxi-mum weight and number of passengers. Besure that weight is properly distributed ac-cording to the boat manufacturers instruc-tions. Overloading or incorrect weightdistribution can compromise the boats han-dling and lead to an accident, capsizing orswamping.

EMU33772

Avoid collisionsScan constantly for people, objects, and otherboats. Be alert for conditions that limit yourvisibility or block your vision of others.

Operate defensively at safe speeds and keepa safe distance away from people, objects,and other boats.� Do not follow directly behind other boats or

waterskiers.� Avoid sharp turns or other maneuvers that

make it hard for others to avoid you or un-derstand where you are going.

� Avoid areas with submerged objects orshallow water.

� Ride within your limits and avoid aggressivemaneuvers to reduce the risk of loss of con-trol, ejection, and collision.

� Take early action to avoid collisions. Re-member, boats do not have brakes, andstopping the engine or reducing throttle canreduce the ability to steer. If you are notsure that you can stop in time before hittingan obstacle, apply throttle and turn in anoth-er direction.

EMU33790

WeatherStay informed about the weather. Checkweather forecasts before boating. Avoid boat-ing in hazardous weather.

EMU33800

Accident reportingBoat operators are required by law to file aBoating Accident Report with their state boat-ing law enforcement agency if their boat is in-volved in any of the following accidents:1. There is loss of life or probable loss of life.2. There is personal injury that requires

medical attention beyond first aid.3. There is property damage to boats or oth-

er property over a certain amount.4. There is complete loss of a boat.Contact local law enforcement personnel if areport is necessary.EMU33870

Boat education and trainingOperators should take a boating safetycourse. This may be required in your state.Many of the organizations listed in the nextsection can provide information about cours-es in your area.You may also want to consider an Internet-based program for basic boater education.The Online Boating Safety Course providedby the BoatU.S. Foundation, is approved bythe National Association of State Boating LawAdministrators (NASBLA) and recognized bythe United States Coast Guard. Most, but notall, states accept this course to meet theirminimum requirements. While it cannot re-place an in-depth course such as one offeredby the U.S. Coast Guard, U.S. Power Squad-ron, or other organization, this online coursedoes provide a general overview of the basicsin boating safety, requirements, navigation,and operation. Upon successful completion ofthe course, the user can download a certifi-cate of completion immediately or, for a smallcharge, request one by mail. To take this freecourse, go to boatus.org.

Basic boating rules (Rules of the road)

Just as there are rules that apply when youare driving on streets and highways, there arewaterway rules that apply when you are driv-ing your boat. These rules are used interna-tionally. (For U.S.A.: and are also enforced bythe United States Coast Guard and localagencies.) You should be aware of theserules, and follow them whenever you encoun-ter another vessel on the water.EMU33700

Steering and sailing rules and sound signalsWhenever two vessels on the water meet oneanother, one vessel has the right-of-way; it iscalled the “stand-on” vessel. The vessel thatdoes not have the right-of-way is called the


Safety information

“give-way” or “burdened”vessel. These rulesdetermine which vessel has the right-of-way,and what each vessel should do.

Stand-on vesselThe vessel with the right-of-way has the dutyto continue its course and speed, except toavoid an immediate collision. When you main-tain your direction and speed, the other vesselwill be able to determine how best to avoidyou.

Give-way vesselThe vessel that does not have the right-of-way has the duty to take positive and timelyaction to stay out of the way of the Stand-Onvessel. Normally, you should not cross in frontof the vessel with the right-of-way. You shouldslow down or change directions briefly andpass behind the other vessel. You should al-ways move in such a way that the operator ofthe other vessel can see what you are doing.“ The general prudential rule ”This rule is called Rule 2 in the InternationalRules and says,“ In obeying and construing these rules dueregard shall be had to all dangers of naviga-tion and collision, and to any special circum-stances, which may render a departure fromthe above rules necessary in order to avoidimmediate danger.”In other words, follow the standard rules ex-cept when a collision will occur unless bothvessels try to avoid each other. If that is thecase, both vessels become “ Give-Way ” ves-sels.EMU25521

Rules when encountering vesselsThere are three main situations that you mayencounter with other vessels which could leadto a collision unless the Steering Rules are fol-lowed:

Meeting: (you are approaching another ves-sel head-on)Crossing: (you are traveling across the othervessel’s path)Overtaking: (you are passing or beingpassed by another vessel)In the following illustration, your boat is in thecenter. You should give the right-of-way toany vessels shown in white area (you are theGive-Way vessel). Any vessels in the shadedarea must yield to you (they are the Give-Wayvessels). Both you and the meeting vesselmust alter course to avoid each other.

MeetingIf you are meeting another power vessel headon, and are close enough to run the risk of col-lision, neither of you has the right-of-way Bothof you should alter course to avoid an acci-dent. You should keep the other vessel onyour port (left) side. This rule doesn’t apply ifboth of you will clear one another if you con-tinue on your set course and speed.


Safety information

6

CrossingWhen two power driven vessels are crossingeach other’s path close enough to run the riskof collision, the vessel which has the other onthe starboard (right) side must keep out of theway of the other. If the other vessel is on yourright, you must keep out of its way; you are theGive-Way vessel. If the other vessel is onyour port (left) side, remember that youshould maintain course and direction, provid-ed the other vessel gives you the right-of-wayas it should.

OvertakingIf you are passing another vessel, you are the“Give-Way” vessel. This means that the othervessel is expected to maintain its course andspeed. You must stay out of its way until youare clear of it. Likewise, if another vessel ispassing you, you should maintain your speedand direction so that the other vessel cansteer itself around you.

EMU25531

Other special situationsThere are three other rules you should beaware of when driving your boat around othervessels.Narrow channels and bendsWhen navigating in narrow channels, youshould keep to the right when it is safe andpractical to do so. If the operator of a power-driven vessel is preparing to go around abend that may obstruct the view of other watervessels, the operator should sound a pro-longed blast on the whistle (4 to 6 seconds). Ifanother vessel is around the bend, it tooshould sound the whistle. Even if no reply isheard, however, the vessel should still pro-ceed around the bend with caution. If you nav-igate such waters with your boat, you willneed to carry a portable air horn, availablefrom local marine supply stores.Fishing vessel right-of-wayAll vessels that are fishing with nets, lines ortrawls are considered to be “fishing vessels”under the International Rules. Vessels withtrolling lines are not considered fishing ves-sels. Fishing vessels have the right-of-way re-gardless of position. Fishing vessels cannot,however, impede the passage of other ves-sels in narrow channels.Sailing vessel right-of-waySailing vessels should normally be given theright-of-way. The exceptions to this are:1. When the sailing vessel is overtaking the

power-driven vessel, the power-drivenvessel has the right-of-way.

2. Sailing vessels should keep clear of anyfishing vessel.

3. In a narrow channel, a sailing vesselshould not hamper the safe passage of apower-driven vessel that can navigateonly in such a channel.

Reading buoys and other markersThe waters of the United States are markedfor safe navigation by the lateral system ofbuoyage. Simply put, buoys and markershave an arrangement of shapes, colors, num-bers and lights to show which side of the buoya boater should pass on when navigating in aparticular direction. The markings on thesebuoys are oriented from the perspective of be-ing entered from seaward (the boater is goingtowards the port). This means that red buoysare passed on the starboard (right) side whenproceeding from open water into port, andblack buoys are to port (left) side. When navi-gating out of port, your position with respect tothe buoys should be reversed; red buoysshould be to port and black buoys to star-board.Many bodies of water used by boaters are en-tirely within the boundaries of a particularstate. The Uniform State Waterway MarkingSystem has been devised for these waters.This system uses buoys and signs with dis-tinctive shapes and colors to show regulatoryor advisory information. These markers arewhite with black letters and orange boarders.They signify speed zones, restricted areas,danger areas, and general information.Remember, markings may vary by geograph-ic location. Always consult local boating au-thorities before driving your boat in unfamiliarwaters.

Propeller selectionNext to selecting an outboard motor, selectingthe right propeller is one of the most importantpurchasing decisions a boater can make. Thetype, size, and design of your propeller havea direct impact on acceleration, top speed,fuel economy, and even engine life. Yamahadesigns and manufactures propellers for ev-ery Yamaha outboard motor and every appli-cation.Your Yamaha dealer can help you select theright propeller for your boating needs. Selecta propeller that will allow the engine to reachthe middle or upper half of the operatingrange at full throttle with the maximum boat-load. Generally, select a larger pitch propellerfor a smaller operating load and a smallerpitch propeller for a heavier load. If you carryloads that vary widely, select the propeller thatlets the engine run in the proper range for yourmaximum load but remember that you mayneed to reduce your throttle setting to staywithin the recommended engine speed rangewhen carrying lighter loads.

Yamaha recommends “Ventless Design Fornew 4-stroke VMAX SHO” for your propeller.For further information, consult your Yamahadealer.To check the propeller, see page 77.

Fuel requirementsEMU41330

GasolineUse a good quality gasoline that meets theminimum octane requirement. If knocking orpinging occurs, use a different brand of gaso-line or premium unleaded fuel. Yamaha rec-ommends that you use alcohol-free gasoline(see Gasoline with Ethanol) whenever possi-ble.The use of a poor quality gasoline may resultin starting and running problems. If you en-counter drivability problems, which you sus-pect could be related to the fuel you are using,we recommend that you switch to a recog-nized high quality brand of gasoline, such asa gasoline that is advertised as Top Tier De-tergent Gasoline. Failure to comply with theserecommendations may also result in un-scheduled maintenance, fuel system dam-age, and internal engine damage.

NOTICEECM01981

� Do not use leaded gasoline. Leaded gas-oline can seriously damage the engine.

� Avoid getting water and contaminants inthe fuel tank. Contaminated fuel cancause poor performance or engine dam-age. Use only fresh gasoline that hasbeen stored in clean containers.

Gasoline with EthanolTwo types of gasoline are commonly avail-able in the U.S.A. for use in automobiles andboats: conventional gasoline without Ethanoland gasoline with Ethanol, which is typicallyreferred to as E10 gasoline. According to fed-eral regulations, E10 gasoline may contain upto 10% Ethanol.A high quality gasoline without Ethanol is thepreferred fuel for your Yamaha outboard mo-tor. However, if gasoline with Ethanol is theonly fuel available in your area, your Yamahaoutboard motor is calibrated to run properlyon fresh E10 gasoline that meets the mini-mum octane requirement specified for thismodel.

NOTICEECM02400

Never use a gasoline for your outboardmotor that contains more than 10% Etha-nol, such as E85 which contains 85% Eth-anol, or gasoline containing any amountof Methanol. These fuels can cause start-

ing and running problems, as well as seri-ous fuel system and internal enginedamage.

Gasoline containing ethanol has severalproperties that may cause boat fuel systemproblems.� Ethanol is a strong solvent (cleaning agent)

that can clean gum and varnish depositsfrom a boat’s fuel system, particularly in old-er boats, as well as tanks and pipes used ingasoline distribution. These released de-posits contaminate the fuel and can causeproblems, such as clogged fuel filters, car-buretors, or fuel injectors, which could re-sult in engine damage.

� Ethanol may dissolve resins used in theconstruction of fiberglass fuel tanks. Thedissolved resins contaminate the fuel andcan cause problems, such as clogged fuelfilters, carburetors, or fuel injectors, whichcould result in engine damage.

� Ethanol is hygroscopic (has a strong attrac-tion to water). Therefore, any water that in-advertently enters the fuel system,including moisture that is absorbed from theair, will mix with the ethanol in the gasoline.If the amount of water is excessive, the eth-anol and water mixture will separate fromthe gasoline in a layer at the bottom of thefuel tank. This ethanol and water mixture isvery corrosive to aluminum fuel tanks andfuel system components.

� The usable life span of E10 gasoline maybe shorter than the normal length of off-sea-son boat storage, causing starting and run-ning problems related to stale fuel.

For more information on using fuel containingethanol, visit: http://www.yamaha-motor.com

Gasoline FiltrationYamaha outboard motors are equipped withinternal fuel filters. However, excessive wateror debris entering your engine’s fuel systemcould prematurely clog the internal filters,causing starting and running problems, fuelsystem damage, and internal engine damage.Therefore, it is recommended that an external10-micron water-separating fuel filter be in-stalled on your boat and serviced frequently.Consult your authorized Yamaha dealer for a10-micron filter that meets your engine’s re-quirements.EMU41340

Gasoline AdditivesGasoline blends change to meet automobileemission regulations and economic condi-tions. Additives, added by gasoline distribu-tors, necessary for proper automobile engineoperation and durability, may not be sufficientfor typical boat applications. Intake valve andcombustion chamber deposits may accumu-late in boat engines more rapidly than en-countered in automotive use. In addition,gasoline used for boating will typically agelonger between refills than gasoline used inautomobiles, resulting in stale and unusablegasoline that may cause starting and runningproblems, fuel system damage, and internalengine damage.Yamaha recommends the use of two Ya-malube gasoline additives to reduce internaldeposits and extend the storage life of gaso-line. Continuous use of Yamalube Ring FreeFuel Additive Plus reduces harmful internaldeposits. Yamalube Fuel Stabilizer & Condi-tioner Plus added to fresh gasoline will helpprotect the fuel system from varnishing whilehelping to keep the gasoline’s octane levelfrom decreasing excessively during storage.Other additives may also be available on themarket that may have varying degrees of ef-

fectiveness. Consult your Yamaha dealerconcerning what may work best for the locallyavailable gasoline and environmental condi-tions.EMU41350

Anti-fouling paintA clean hull is required to maintain your boat’sperformance. Boats moored in the watershould be protected from marine growth (bar-nacles, mussels, and marine plants). If ap-proved by regulations for your area, thebottom of the hull can be coated with an anti-fouling paint to inhibit marine growth.Anti-fouling paints specifically formulated foruse on aluminum may be applied to the out-board motor. The original Yamaha paint sur-face may be scuffed lightly before applyinganti-fouling paint, but do not remove the origi-nal paint. Removal of the original paint will in-crease the rate of corrosion.

NOTICEECM02410

Anti-fouling paint for fiberglass and woodmay contain materials, such as copper,graphite, and tin, that can cause corrosionif applied to aluminum boats and outboardmotor components. Never apply thesetypes of paint to your outboard motor be-cause rapid corrosion damage could oc-cur.

Sacrificial anodes are attached to the out-board motor to provide corrosion protectionand must never be painted.

NOTICEECM02420

Painted sacrificial anodes will not providecorrosion protection.

Fuel flow meterThe fuel flow meter displays the amount offuel flow over a one-hour period, at the currentrate of engine operation.� The fuel flow meter displays gallons/hour or

liters/hour according to operator prefer-ence. Select the desired units of measure-ment by setting the selector switch on theback of the gauge during installation.

� The fuel consumption meter and fuel econ-omy meter will indicate the same unit ofmeasurement.

Fuel flow readings are not accurate when theengine is operating under about 1300 r/min.As the fuel pump cycles on and off, the displayindicates either no fuel flow or higher flow thanthe actual average use.Dual engine users: the fuel flow meter candisplay the fuel flow of either or both engines.

To change the fuel flow display, press the“ ” (set) button repeatedly until the gaugedisplays “ ” (for fuel flow to the starboard en-gine only), “ ” (for fuel flow to the port engineonly), or “ ” (for total fuel flow both engines).EMU36090

If twin engines are installed on your boat, thegauge will only display the total fuel economyof both engines.� Fuel consumption varies greatly with boat

design, weight, propeller used, engine trimangle, sea conditions (including wind), andthrottle position. Fuel consumption also var-ies slightly with the type of water (salt, fresh,and contaminate levels), air temperatureand humidity, cleanliness of the boat bot-tom, engine mounting height, skill of the op-erator, and individual gasoline formulation(winter or summer fuel and amount of addi-tives).

� The Yamaha digital speedometer and fuelmanagement meter calculates speed,miles traveled, and fuel economy by watermovement at the stern of the boat. This dis-tance can vary greatly from the actual dis-tance traveled because of water currents,sea swells, and the condition of the waterspeed sensor (if partially plugged or dam-aged).

� Individual engines may slightly vary in theirfuel consumption due to manufacturingvariations. These variations can be evengreater if the engines are of different yearmodels. In addition, variations in propellers,even of the same basic dimensions of thesame design, can also cause a slight varia-tion in fuel consumption.

EMU26782

Twin-engine speed synchronizerThis gauge displays the difference in enginespeed (r/min) between the port and starboardengines for reference purposes when syn-chronizing the two engines’ speeds.

If the two engines’ speeds are not synchro-nized while cruising, adjusting trim angle orthrottle can synchronize them.If large differences in trim angle or throttle areneeded to synchronize the engines, consultyour Yamaha dealer for adjustments to thethrottle cables.

EMU41212

InstallationThe information presented in this section is in-tended as reference only. It is not possible toprovide complete instructions for every possi-ble boat and outboard motor combination.Proper mounting depends in part on experi-ence and the specific boat and outboard mo-tor combination.

WARNINGEWM02572

� Overpowering a boat could cause se-vere instability. Do not mount an out-board motor with more horsepower thanthe maximum rating on the capacityplate of the boat. If the boat does nothave a capacity plate, consult the boatmanufacturer.

� Improper mounting of the outboard mo-tor could result in hazardous conditions,such as poor handling, loss of control,or fire hazards. Have your Yamaha deal-er mount the outboard motor properly.

EMU41270

Mounting the outboard motorThe outboard motor should be mounted sothat the boat is well balanced. Otherwise, theboat could be hard to steer. Mount the out-board motor on the centerline (keel line) of theboat.

EMU41063

Mounting heightThe mounting height of your outboard motoraffects its efficiency and reliability. If it ismounted too high, propeller ventilation mayoccur, which will reduce propulsion due to ex-cessive propeller slip, and the cooling waterinlet for the cooling system may not get ade-quate water supply, which can cause engineoverheating. If the engine is mounted too low,water resistance (drag) will increase, therebyreducing engine efficiency and performance.The optimum mounting height depends onthe combination of the boat and outboard mo-tor. Consult your Yamaha dealer or boat man-ufacturer for further information ondetermining the proper mounting height.

NOTICEECM01634

� Make sure that the idle hole is highenough to prevent water from enteringthe engine even if the boat is stationarywith the maximum load.

� Incorrect engine height or obstructionsto the smooth flow of water (such as thedesign or condition of the boat, or ac-cessories, such as transom ladders ordepth finder transducers) can create air-borne water spray while the boat iscruising. If the outboard motor is operat-ed continuously in the presence of air-borne water spray, enough water couldenter the engine through the air intakeopening in the top cowling to cause se-vere engine damage. Remove the causeof the airborne water spray.

Breaking in engineYour new engine requires a period of break-into allow mating surfaces of moving parts towear in evenly. Correct break-in will help en-sure proper performance and longer enginelife. NOTICE: Failure to follow the break-inprocedure could result in reduced enginelife or even severe engine damage. [ECM00801]

EMU41222

Procedure for breaking in engineYour new engine requires a period of 10hours break-in so that mating surfaces ofmoving parts wear in evenly.

Operate the engine in the water under load (ingear with a propeller installed) for 10 hours asfollows. When breaking in the engine, avoidextended idling, rough water, and crowded ar-eas.1. For the 1st hour of operation:

Operate the engine at varying speeds upto 2000 r/min or approximately 1/2 throt-tle.

2. For the 2nd hour of operation:Increase the engine speed until the boatis on plane (but avoid full-throttle opera-tion), and then back off on the throttlewhile keeping the boat at a planingspeed.

3. For the remaining 8 hours of operation:Operate the engine at any speed. How-ever, avoid operating at full throttle formore than 5 minutes at a time.

4. After the 1st 10 hours of operation:Operate the engine normally.

Cooling waterCheck for a steady flow of water from the cool-ing water pilot hole. A continuous flow of waterfrom the cooling water pilot hole shows thatthe water pump is pumping water through thecooling water passages.

TIP:When the engine is started, there may be aslight delay before water flows from the cool-ing water pilot hole.

NOTICEECM02250

If water is not flowing out of the coolingwater pilot hole at all times while the en-gine is running, overheating and seriousdamage could occur. Stop the engine andcheck whether the cooling water inlet onthe lower case or the cooling water pilothole is blocked. Consult your Yamahadealer if the problem cannot be locatedand corrected.

Trimming outboard motor

WARNINGEWM00740

Excessive trim for the operating condi-tions (either trim up or trim down) cancause boat instability and can make steer-ing the boat more difficult. This increasesthe possibility of an accident. If the boatbegins to feel unstable or is hard to steer,slow down and/or readjust the trim angle.

The trim angle of the outboard motor helpsdetermine the position of the bow of the boatin the water. Correct trim angle will help im-prove performance and fuel economy whilereducing strain on the engine. Correct trim an-gle depends upon the combination of boat,engine, and propeller. Correct trim is also af-fected by variables such as the load in theboat, sea conditions, and running speed.

Adjusting trim angle

WARNINGEWM02471

� Make sure that all people are clear of theoutboard motor when adjusting the trimangle. Body parts can be crushed be-tween the outboard motor and the clampbracket when the outboard motor istrimmed or tilted.

� Use caution when trying a trim angle forthe first time. Increase speed graduallyand watch for any signs of instability orcontrol problems. Improper trim anglecan cause loss of control.

� If the outboard motor is equipped with apower trim and tilt switch located on thebottom cowling, use the switch onlywhen the boat is at a complete stop withthe engine off. Do not adjust the trim an-gle with this switch while the boat ismoving.

Adjust the outboard motor trim angle usingthe power trim and tilt switch.

To raise the bow (trim-out), push the “ ” (up)side of the switch.To lower the bow (trim-in), push the “ ”(down) side of the switch.

Make test runs with the outboard motor set atdifferent trim angles to find the position thatworks best for your boat and operating condi-tions.EMU41081

Adjusting boat trimWhen the boat is on plane, a bow-up attituderesults in less drag, greater stability and effi-ciency. This is generally when the keel line ofthe boat is up about 3 to 5 degrees. With thebow up, the boat may have a greater tenden-cy to steer to one side or the other. Compen-sate for this as you steer. When the bow of theboat is down, it is easier to accelerate from astanding start onto plane.

Bow UpToo much trim-out puts the bow of the boattoo high in the water. Performance and econ-omy are decreased because the hull of theboat is pushing the water and there is more airdrag. Excessive trim-out can also cause thepropeller to ventilate, which reduces perfor-mance further, and the boat may “porpoise”(hop in the water), which could throw the op-erator and passengers overboard.1.

Bow DownToo much trim-in causes the boat to “plow”through the water, decreasing fuel economyand making it hard to increase speed. Operat-ing with excessive trim-in at higher speedsalso makes the boat unstable. Resistance atthe bow is greatly increased, heightening thedanger of “bow steering” and making opera-tion difficult and dangerous.

EMU27946

Tilting up and downIf the engine will be stopped for some time orif the boat is moored in shallows, the outboardmotor should be tilted up to protect the propel-ler and lower case from damage by collisionwith obstructions, and also to reduce salt cor-rosion.

WARNINGEWM01543

Make sure that all people are clear of theoutboard motor when tilting the outboardmotor up and down. Body parts can becrushed between the outboard motor andthe clamp bracket when the outboard mo-tor is trimmed or tilted.

NOTICEECM00991

� Before tilting the outboard motor, followthe procedure under “Stopping engine”in this chapter. Never tilt the outboardmotor while the engine is running. Se-vere damage from overheating can re-sult.

Transporting and storing out-board motor

WARNINGEWM02551

� Leaking fuel is a fire hazard. When trans-porting and storing the outboard motor,close the fuel cock to prevent fuel fromleaking.

� Never get under the outboard motorwhile it is tilted, even when the tilt sup-port shaft is installed. Severe injurycould occur if the outboard motor acci-dentally falls.

The outboard motor should be trailered andstored in the fully tilted-down position. If theoutboard motor cannot be trailered in the fullytilted-down position, the outboard motor mustbe secured in the tilted-up position using asupport device, such as the Yamaha Traile-ring Support.EMU41001

Storing outboard motorWhen storing your Yamaha outboard motorfor prolonged periods of time (2 months orlonger), several important procedures mustbe performed to prevent excessive damage. Itis advisable to have your outboard motor ser-viced by an authorized Yamaha dealer prior tostorage. However, you, the owner, with a min-imum of tools, can perform the following pro-cedures.

NOTICEECM02281

Store the outboard motor in a dry, well-ventilated place, not in direct sunlight.

EMU41380

Conditioning and stabilizing gasolineWhen preparing to store a boat for extendedperiods (2 months or longer) it is best to com-pletely remove all gasoline from the boat’s

fuel tank(s). If it is not possible to remove thegasoline, add one ounce of “Yamalube FuelStabilizer & Conditioner Plus” to each gallonof gasoline in a full tank of gasoline to providefuel stability and corrosion protection.

TIP:Do not fill the fuel tank(s) to the point of over-flowing. Approximately 7/8 full will allowenough space in the fuel tank to prevent gas-oline purging from the fuel tank vent due to ex-pansion with temperature changes.Do not cap the fuel tank vent. Excessive pres-sure could damage the boat and motor’s fuelsystems.A partially filled fuel tank, less than 7/8 full butnot completely empty, is not recommended.Air space above the gasoline allows air move-ment which can bring in water through con-densation as the air temperature changes.Condensation inside the fuel tank can causecorrosion problems and phase separation ofgasoline containing ethanol.Consult your Yamaha dealer concerning pre-ventative measures that may work best for thegasoline and environmental conditions in yourarea.EMU28305

Inspecting spark plugThe spark plug is an important engine compo-nent. The condition of the spark plug can indi-cate something about the condition of theengine. For example, if the center electrodeporcelain is very white, this could indicate anintake air leak or carburetion problem in thatcylinder. Do not attempt to diagnose anyproblems yourself. Instead, take the outboardmotor to a Yamaha dealer. You should peri-odically remove and check the spark plug be-cause heat and deposits will cause the sparkplug to slowly break down and erode.To remove the spark plug1. Remove the flywheel magnet cover.

2. Remove the ECM (Electronic ControlModule) cover.

3. Remove the bolt that is securing the igni-tion coil, and then remove the ignitioncoil. NOTICE: Do not use any tools toremove or install the ignition coil. Oth-erwise, the ignition coil coupler couldbe damaged. [ECM02330]

4. Remove the spark plug. WARNING!When removing or installing a sparkplug, be careful not to damage the in-sulator. A damaged insulator could al-low external sparks, which could leadto explosion or fire. [EWM00561]
