I've currently got a Renegade 23P on the boat and it runs well, but seems a little slow on top end. I've been told the boat is a low-mid 60's boat with a 175HP. I'm running about 58mph alone in the boat. Compression on the motor is good and spark plugs just replaced, though I'm unsure of the RPM's I'm currently running. Tach started bouncing suddenly.

I've also got a Renegade 24P that I haven't tried yet.

The boat does have a 6" jackplate.

Any suggestion on which prop to run?
