I have a 2006 Challenger SV-30 496 HO that is a real deep deep hull, no step. I need to dial in the prop. I currently have a 24P bravo 1 and I'm only turning 4400 rpm. I actually think this boat would perform better with a 3 blade prop. Any suggestions?

I would try a 25 pitsh 3 blade , you need the rs to be higher than 4400 , if 3 blade does not feel rite try a 23 4 blade. bblades on here has a program to try it before you buy it.
