Can anyone tell me the prop pitch and diameter I need for my 1984 C&C 35-3 with a Yanmar 3GMF 20 horsepower. Also looking for the Gear reduction Ratio or where I can find that info. Thanks in advance!

We have surveyed 6 of these and all had three blade feathering props, Kanzaki KM3-A gears with 2.01 : 1 reduction

The prop manufacturers have a form you can fill out online which will answer your question.

You do need to determine the transmission ratio. I recall it's on a plate on the transmission. My 3GM30F of the same vintage has a ratio of 2.66.
