I have a 2008 Crest Pontoon II LE XRS that weight approx 2700lbs dry. I also have a Honda BF115A outboard that needs a new prop. I do not know my current RPMS or top speed. I would guess around 25mph. When searching for a new prop by entering serial number to engine I got approx 20 different props listed with part numbers. My question is what pitch 3 blade prop should I get to replace it with????
