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.

Yanmar Marine Diesel EngineYanmar Marine LH Diesel Engines

4-cylinder, direct injection, heat exchanger cooling.

Turbocharged or turbocharger + intercooling type.

Angle drive (marine gear) is standard except for 4LH-STE

4LH-STE supplied without marine gear.

>> Specifications for LH Series 73.5 ~ 169.0kW (99.9~230.0hp)

The best engine in its class just got better
The high power configuration comfortably allows the 4LHA to stand world class in all three main areas of comparison namely:

  • power-to-weight ratio
  • power-to-displacement ratio
  • power for a given set of engine dimensions

The 4LHA is designed for use with a variety of marine gearboxes, including straight, angled and vee-drive ZF-Hurth units. Turbocharger has a waste-gate boost compensator which improves acceleration (4LHA-STP)

Environmentally engineered
This engine shares all the benefits of Yanmar's commitment to protecting the environment in which we live. Features such as:

  • low noise, low vibration, highly economical use of fuel.
  • low smoke, especially when accelerating or idling.

Vibration has been kept at a low level due to the use of special steels in the block and other critical areas.

Wide range of applications
Being substantially slimmer configuration means easy installation, even in tight locations. Repowering in most instances is straight-forward; the total package being slimmer, shorter and less bulky than previous models.

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.
