For motorboat use, Yanmar makes main engines up to around 300kW. Like sailboat propulsion units, their reliability is legendary; but they are also light, compact and powerful.
The Saildrive has been found to improve boat balance, give more maneuvrability and better thrust. Drive by the famous Yanmar diesels, these Saildrives put a lot of dependable power in the right place in a boat.
Combustion power acts directly on the toroidal piston crown, boosting energy, decreasing thermal losses. Extra high output creates the tough torque needed for heavy duty jobs.
Now instead of fickle performance common to so many gasoline engines, the diesel outboard presents operational savings and long-term strengths that make pure sense to the commercial operator.
If you are looking for a silent, compact, power source, with minimum fluctuations, the new YDG is waiting for you.
These generators are purpose built to match the engine to the constant running load of the submersible pump, and alternator to the high starting capacity of the pump motor.

1. We've closed the gap on waste

High Top Rings

A small change with a significant impact on the all- important combustion performance is the high aspect design of the piston. To reduce dead volume around the crown the top ring has been placed higher than usual. This visibly cuts down the volume of unburnt waste gases. It also increases combustion efficiency.

Metal Gasket

So does a new head gasket. This safe metal gasket is 70% thinner than those conventionally used so far. The thinner gasket concentrates combustion pressure even more.

Semi-open Deck

To handle the better combustion and higher thermal loads we have designed a two-tier cooling chamber. This gives direct cooling to the ring area.

2. The Maximized Mix

The fuel-air mixture that hits the combustion chamber has to be near ideal for most effective combustion and the greatest torque. The computer designed apertures in the intake port of the TNE give swirl characteristics that ensure this. Raw gas is virtually excluded, meaning less smoke and smell during low load operation.

3. FIE-The Maker's Match

Nobody can make fuel injection equipment as well as the people who make diesel engines. Yanmar's unique role as an FIE developer means the heart of the TNE is matched precisely with the rest of the system. Such close coordination of parts means that every drop of fuel serves the combustion process, leaves no waste. You also get the asset of having one source for all spares.

Nozzles

Injection perfection is the result of a system which atomizes and mixes fuel at extremely high pressures. It cuts out noxious emissions at both high and low load, slashing raw gas exhaust.

Fuel Injection Pumps

Spot-on pump performance controls fuel injection over the whole speed range. Its success in any type of drive duty is due to a new governor mechanism and an enlarged plunger. Total stability is maintained at all load demands.

SILENT

1. The 'Peaceful' Piston

Added piston stability comes from a steel strut inserted in the piston. This reduces expansion of the alloy and neutralizes expansion disparity. The result is finer tolerances, reduced blow-by gas and less piston slap which is even further reduced by an offset piston pin that cuts down on centrifugal forces.

2. Crankshaft-Rod Mating System

At Yanmar we don't simply put together any crankshaft and piston rods. Because every crankshaft has its own tolerance characteristics, each one is carefully mated to like rods. This helps minimize bearing clearances and create the smoothest stroke action.

3. One Low-clash Mesh

Specially designed gear teeth have a newly designed 'roll-off' surface profile. There's almost no clash, no noise and no backlash.

4. Flywheel Noise Barrier

Flywheel noises, usually created by air turbulence, are sealed inside the flywheel housing by a special flange forged into the housing.

Yanmar Spare Parts Its extraordinarily low fuel consumption is a result of this super-precise FIE and its direct injection system-the first ever to go into this type of engine. Now instead of fickle performance common to so many gasoline engines, the diesel outboard presents operational savings and long-term strengths that make pure sense to the commercial operator. When it comes to marine diesels, reliability is most highly valued factor of all. Each Yanmar diesel has been designed and manufactured using knowledge accumulated steadily by us since our founding in 1912. They are built for heavy loads and long running hours and can be matched up with any of the Yanmar engine protection or control systems. If you are looking for a high quality generator, consider one of the models built by Yanmar. Yanmar was founded in 1912 and developed the world's first commercially viable small diesel engine in 1933. For boats, the ability to slot an engine as low down as possible, or to mount twin engines low in the vee of the boat has been critical. The Saildrive has been found to improve boat balance, give more maneuvrability and better thrust. Drive by the famous Yanmar diesels, these Saildrives put a lot of dependable power in the right place in a boat.
