Does anyone know what gear reduction ratio this boat’s transmission
has? It is equipped with a Kanzaki model KM2P transmission, but the
name plate does not have the ratio stamped next to the two words “Gear
Ratio”. The boat’s engine is a Yanmar 2GM20F. The hull number is #29,
an '87 model.

I don’t know what the difference is between the KM2P and the KM2C,
but the Yanmar Service Manual calls out the Kanzaki KM2C mated to
the Yanmar 2GM20F and the transmission ratios are either
2.21,2.62,or 3.22 in forward and 3.06 in reverse. Every Yanmar 2GM2F
or 2GM20F I’ve ever seen have the 2.62 ratio. If you are in doubt,
Place a mark on your shaft and rotate the engine manually through 1
revolution. You’ll get a good idea.
