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.
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 3YM30AE models. The 3YM20 and 3YM30AE were designed as a direct upgrade for the legendary 2GM20 and 3GM30E 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
More and less: 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.
