3400 RPMS = 55 MPH
3800 RPMS = 60 MPH
I seem to get A LOT of prop slip between 2800-3200 rpms so I avoid that range. Above 3200 I'm estimating 8-10% slip.

About 3300 RPM is 32-35 mph depending on trim ballast for me, not typical boat for OSO, a 20 ft bowrider setup for wakeboarding.

34'' bravo 1 lab 3000rpm = 43.6, 3500 = 55.4 mph
32 5p-x hydromotive Same as above a little smoother same top speed
30 Maximas 5 blade 3000rpm = 45.0, 3500 = 57.3 mph non labbed, 3 mph slower top end, excellent out of the hole.
31 Hering 5 blade 3000rpm 49.9mph, 3500 = 60.1mph a little slow on plane, +3 mph faster top end than all above.
