I took a guess on my first set of props for my re- rigged 36 foot sonic ss. It's an older hull a 1986, stepped hull. Have it rigged with 415 hp 502 mpi motors and trs drives with velvet trannies. Raised the drives about an inch and prop depth is about 5 ". Put on a set of labbed mirage + 25 p with extra cup. Planes super fast with tabs down but top speed is low. 4300 rpm at 55 mph gps. Am thinking 22p 4 blades or 23 p mirage. Suggestions?

Slip is high. Try some 23 Revolution 4's.
We have them for testing.

Yeah my slip is really high for some reason!

When I first posted I wasnt getting full throttle (cable adjustment issues).

Now I'm getting 59MPH on GPS with 4600 RPM....and able to hit the rev limiter at 4800 RPM (which seems low but seems to be stock on my motor). Slip calculates to around 18% which seems high.

Am about to try some 24P Bravo 1s. Would that be a good choice?

Worth a try but may have a little too much stern lift.

I left a phone message with you yesterday. I want to talk in person. My 25P props are a little damaged so maybe that's part of the problem.
I will try these Bravo 1s and see how they work.

So you think they'll lift my stern more? I guess its hard to have bow lift on a longer boat. Should also mention that am fully loaded with fuel too (1500 lbs).

A Rev4 would work better?
