My 28 partycat is getting repowered right now with a 600SC. The engine that came out, 7.4 merc, had 385hp. The boat has a bravo III with 24 pitch props on it. Im looking at a couple of used props and I am stuck between a 28p and 30p props. I know that the 30 (cupped) is a big jump, but the boat only ran about 55mph with the 7.4 and the hull is just starting to perform at that speed.
what to do? go with the 28p and have them redone if not enough or 30p and hope the damn thing will even get on a plane?
