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.

1GM - More power, same size
Yachtsmen looking for extra power without extra size and weight can find it in Yanmar's new 1GM10 diesel engine. Yanmar have up-powered their popular 1GM model by 20% to re-create its trusty performance at a higher 6.7kW, with negligible change in size, weight and shape. Its only gain is a heftier flywheel to maintain smooth running and easy starting.

YM Series
The naturally aspirated new generation YM series continues the Yanmar tradition of providing boaters with superior technology - quiet, compact power to be relied upon. The latest lightweight propulsion developments from the diesel leader Yanmar are the all new 2YM15, 3YM20 and 3YM30 models. The 3YM20 and 3YM30 were designed as a direct upgrade for the legendary 2GM20 and 3GM30 models they replace. The new 2YM15 is an additional model to what is recognized already as the most complete line up of marine engines in the business. With the added benefit of simplified maintenance due to the new location of the sea-water pump and all other service points being together near the engine front these units no doubt are already on track to be recognized as the best-in-class auxiliary power for sailboats and tough, reliable primary power for small motor craft.

Best-in-class diesel power
With more displacement, more torque, more amps, yet even quieter, with less smoke than ever, EPA Tier 2 emission regulations and BSO/SAV stage 2 compliant. The flat power curve allows you to choose the propeller size to best match your application.

The same
For ease of installation and for repowering, these latest 3 cylinder models are the same size as their predecessors, with identical footprints.

All new
Completely re-designed cylinder block and indirect combustion system for optimised performance and maximum economy. New compact control panel, new injection pump, and new electric stop solenoid.

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.
