So I have a 1993 seafarer 226 with a 93 Yamaha 200hp. I am currently running a 15.5 x 17p Yamaha ss 3 blade. With 3 people and 3/4 fuel onboard I’m running wot 5100 and @37 mph. It’s has hardtop, pulpit, cooler, 15ga water tank an potty onboard. So heavy boat. Most time I have 4 adults as well. Cruise is 4000 at 28mph loaded up. So Question is I have tried a 15x15 ss 3 blade prop and wot was 57-5800 rpms. Dropped to a 17 and only 5100. I bought boat with a 13 3/4 x 19p aluminum and would only turn 46-4700 wot. What prop is best for my set up. Also should I try a 4 blade to help the lower hp motor? Thanks.
