Re: Super maramu max prop

Hi Rob,

if you give PYI a call, they are very helpful. They will need to know your engine, type of boat, diameter of the prop, and left hand rotation. I believe the diameter is 21”, but assuming you are out of the water, you can measure to be sure. We re-powered with a Yanmar, and the pitch PYI came up with was exactly correct when we sea trialed it. 

Good luck.
