Yanmar Gearbox

KM3V

Kanzaki-built V-drive gear with a mechanical cone clutch that Yanmar supplied on the V-drive versions of the 3GM30(F).

The KM3V is a V-drive marine gear with a mechanical cone clutch acting for both ahead and astern. Yanmar's GM-series operation manual lists it as the gear for the 3GM30(F) V-drive engine with a 2.61:1 forward ratio and a dry weight of 19.5 kg, and Yanmar's parts catalogue shows a separate V-drive housing and V-drive shaft for it.

Production years were not found; it belongs to the GM-series era.
