GM/YM SERIES

With the largest displacement and smallest dimensions in their class, these thoroughbred workhorses provide sure-fire auxiliary power for sailboats and durable primary power for small motorboats. The naturally aspirated new generation YM series continues the Yanmar tradition of providing boaters with superior technology – quiet and compact power that can be relied upon.

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.

The GM/YM Series engines are available in both shaftdrive and saildrive configurations.
