Default Re: Prop for 250 2 stroke Yami

Im no expert but I can tell you take Chucks advise and talk to Frank.I made the mistake of reading a post he did a few weeks ago after I bought a prop trying to get more RMPs.I to went from a 19 to a 17.I did not get very good results because my old prop was 13 3/4 diameter and new prop was 14 1/2 and the new prop was alumiuum and old SS.Franks post said I think every 1/4 inch you go up in diameter is like adding 1" pitch.the alumium made a factor not in my favor. again im no expert but I have been told to to get a matching diameter SS prop {13 3/4} by 17 pitch. I hope this helps.Keith
