20200926_140446.jpg Can someone with some experience give me some advise, I have a Yamaha 175 sho four stroke it came with a factory installed Yamaha Reliance series 3 blade 17P stainless. The problem is I`m reaching 6300 + rpm and after talking to Yamaha customer service they recommend 6000-6100 rpm. I have Strong hole and mid range, sometimes it will lose its bite in a turn but not to great on top end (50mph) but I guess this type of boat isn`t made for that.

My question is I want to go to a 4 blade prop should I go up to a 18P 4 blade so I don`t lose any top end or should I stay a 17P 4 blade and lose top end speed?

I have read a 4 blade same pitch will have lower rpm and lose on the top end?

Thanks Mobile1/Steve
