You had a cleaver prop on it? Why would you have a racing prop on a V20?
I'd think that a 17p Alum prop on a 150 would be just about ideal. Perhaps a 15 if you go SS.

Just make sure that it clears the anti-vent plate on your engine. And I'd try to get one to borrow first before plunking down some hard earned bread. make sure it's what you're looking for in your prop. And make sure that your WOT rpms are in the correct range for that prop.

I'm running 150 yamaha 2 stroke with about the same - 14.5 x 17 stainless. It might be 14 x 17? Can't remember but I know it 14 or 14 something x 17. It is perfect to me. Runs up to 5400 RPMs or so. I don't think you'd be happy w/ 15 x 15, but then again I'm no prop man either! Destroyer is right on about try before you buy (if you can).

Yea I agree, I spoke with a yamaha dealer and giving the weight of the V20 he said go with a 14.5 X 17 prop that should be my best bet. So I orderd one $136 it will be in Monday so no fishing this weekend
 any way thanks for all the advise
