LUTZ W. LESTER Managing Director

Driven by innovation

The time of glorious days for real new inventions in the area

of internal combustion engines seems to be long gone.

Engines become more and more efficient and offer many

variations. Enthusiastic innovative genius coupled with an

open mind made us to rethink mature technology. The prin-

ciple of the twin crankshaft concept has received a name –

NEANDER.

VISION DEVELOPED

Our origin

Before the change of the millennium our passions for engines

has only been applied to two-wheelers. Our intention was

to put the incredible torque of a turbo diesel engine on the

road. Our vision was a unique motorcycle with a powerful

100 HP turbo diesel engine.

In 2003 this vision found a home through the foundation of

NEANDER Motorfahrzeuge GmbH which has been transfor-

med 2006 into NEANDER Motors AG. Merely three years

later – 2009 – the ingenuity of the idea had been recognized

e.g. by the Schmidt-Römhild Technology-Award presented by

the Ministry of Science, Economy and Traffic of Schleswig-

Holstein, Germany.

We grow with our success. Thus the idea of using the

NEANDER technology for marine came into vision. The rea-

lization of this thought took place quickly in the same year –

in 2009 NEANDER Shark GmbH was founded as a 100%

subsidiary of the NEANDER Motors AG. Ever since NEANDER

Shark has vigorously implemented the unique concept in the

marine world.

Outstanding engineers and engine experts joined the

NEANDER project soon. Lutz W. Lester´s talent of generating

enthusiasm caused “innovators” to accept the challenge and

support NEANDER. Those came with the experience from

companies like Porsche, Mercury Marine, Mahle and MuZ

Motorcycle. With their know-how and energy it was made

possible to explore the unknown path.

The aim: The worldwide first turbo diesel outboard engine –

from the idea to series production.

VISION LIVED

STEFAN UTERMANN Sales Manager

A modern outboard engine nowadays has to comply with

strict requirements, especially in respect of commercial appli-

cations. Besides the priority of safety on board, efficiency and

economical aspects are most important.

A fisherman expects reliable performance and efficiency

during his day-to-day business. Stable performance is funda-

mentally required in case of emergency for police and military

forces as well as for the use of tender boats of cruise liners

and container ships.

Particularly for charter businesses safety and low operational

cost are essential. The boats have to run reliably during the

in general short season. If required an outboard is changed

quickly and the client can go on with his boat trip.

PERFORMANCE EFFICIENCY

All these demands are covered by the NEANDER Shark

Turbo Diesel outboard engine:

• Low fuel consumption

• Outstanding reliability

• Ease of access to diesel fuel

• Powerful drive

• Diesel engine durability and reliability

The fuel efficiency of the turbocharged diesel engine ensures

higher range compared to a gasoline power unit and requires

less stops to refuel. The outstanding efficiency and the fuel

prices make the NEANDER engine pay off rapidly.

PERFORMANCE EFFICIENCY

Traditionally diesel is the fuel in marine. Thus the usage

of diesel assures ideal logistics and great reliability during

operation – particularly on boats made for outboards! In

addition the inflammability of diesel is by far much less than

of gasoline which, regarding the fuel storage on board, offers

a great benefit for safety and expense.

As no high voltage ignition system is used on a diesel engine

the NEANDER Shark is particular in areas which are critical in

respect to flammability, like oilfields. Areas which up to now

were unreachable for outboard engines.

The NEANDER Shark Turbo Diesel outboard has been

developed for various different applications. Pushing heavy

vessels, trawling, or idling for hours – the NEANDER engine

is designed to last!

The powerful drive is demonstrated by the excellent tor-

que behavior. The chart on the right side compares our

NEANDER Shark (36,8 kW / 50 HP at the propeller shaft)

with a standard gasoline outboard (44,13 kW / 60 HP).

Torque Comparison

The application of approved and commonly used engine

parts assures endurance and reliability. Even after endless

hours of operation your NEANDER Shark will not let you

down – provided service is done according to plan – will start

up each time like it would be its first time. Therefore you

achieve economic stability and performance efficiency.

The NEANDER technology is based on the latest findings of

modern combustion engines. The novelty of the NEANDER

engine concept is the application of the twin crankshafts.

This design principle enables an efficient engine design.

Providing almost vibration-free operation of the engine.

The NEANDER Shark was especially developed for the

challenges of the commercial boating.

PERFORMANCE SERVICE

By your decision for a NEANDER Shark you take performance

and efficiency on board. However, in the unpredictable case

of something going wrong we offer you a worldwide reliable

and professional service with our powerful partners. Thus

from the first day of service the supply of parts is ensured.

By long-standing relationships with brilliant production part-

ners like Selva Marine, Bosch, Borg Warner and many more

we assemble a reliable supply of spares. A network of speci-

ally trained service personnel of well-known and experienced

distributors brings our service to perfection.

CLAUS BRÜSTLE Managing Director

Today’s marine engine market is divided into two major

segments, commercial and recreational use of propulsion

systems. At present no diesel outboard exists in the market

segment of 30 to 52 kW (40 to 70 HP), a segment interesting

for commercial use and which is defined by transport, hau-

ling, commercial fishing and others.

In the smaller engine segments with power below 75 kW

(100 HP) gasoline engine technology is the dominant and

sole available power. Due to their favorable compactness,

ease of installation, serviceability, weight and also cost

outboard engines govern the market.

TECHNOLOGY INNOVATION

The diesel torque to weight ratio, beneficial specific fuel

consumption and the tax-free diesel fuel for commercial

applications make diesel engines extremely attractive. Also

other typical outboard engine applications like rescue boats

on larger ships are much more comfortable and more econo-

mical with a diesel outboard. There is another outstanding

advantage: No need to maintain dual fuel storage capacity

onboard with all aspects of safety and logistics.

One focus during developing a diesel outboard engine is

the vibration level. Typical diesel vibrations would make the

whole boat shake.

The patented NEANDER Shark twin crankshaft design elimi-

nates mass forces using the 2 counter rotating crankshafts.

On top this design provides a role torque free operation of

the engine on the transom. This leads to a smooth running

behavior which is beside the NEANDER engine only achieved

by multiple cylinder diesel engines!

TECHNOLOGY INNOVATION

The key enabler for a dual crankshaft engine with a constrained

piston movement by two con-rods with theoretically no piston

side forces is provision for forgiveness towards tolerances.

These can lead to off-design positions of the piston in its cylin-

der bore and unfavorable mechanical effects like scuffing,

sticking or simply higher friction as the least bad of effects.

Inventing and introducing a so-called space ball design resol-

ved the problem, giving the piston the additional degree of

freedom of rotational adjustment around the two piston pins.

The cylinder block of the engine is an Aluminum design, closed

deck with dry cast iron cylinder sleeves pressed in for robust-

ness and simple serviceability.

The cylinder head, block and bedplate are joined by so called

long bolts, which reach from the head into the bedplate main

bearing saddles. This design allows the structural aluminum

parts to be under compressive stress only, which is favorable

for the durability of all structural components. For vibrational

rupture protection, dampening, the bolt holes are connected

via calibrated oil holes into the main oil gallery. This design

strategy was applied successfully to other high performance

marine and automotive engines in the past.

Long bolts join cylinder head, block and bedplate.
