Prop for Morgan OI w/ Yanmar 3GM30F
We recently purchased our ''79 OI. Original owner purchased her with a Perkins. At that time the Yanmar 3GM30F was optional. Years later the second owner repowered with the Yanmar 3GM30F but evidently did not replace the prop. We would now like to purchase the correct prop. Can anyone tell us what the correct prop specifications are for our OI 33 with the Yanmar 3GM30F. Any information is appreciated.
