I have a '93 85hp Yami that is on the back of my 25ft pontoon boat. I think my W.OT. is a little to high (6000rpm) and would like to consider another prop. The problem is the prop that is on there has no size marked on it. Trust me I have looked for it several times and all over the darn thing. How can I find out what pitch I have so that I can go from there?
