I'm currently running a 3 blade stainless 17P on my 215 Aquasport and it tops out at about 6100 RPM at about 40 MPH..Yamaha recommends running 5500-6000 RPM. I'd like to plane at lower speeds so I'm thinking 4 blade.Should I go up a pitch to 18P or stick with 17P because a 4 blade would decrease RPM on it's own? The Yamaha site has an "Offshore1" or an "Ultima4". Any experience with either ,or should I look for another brand than Yamaha?
