Sorry to have so many questions, but thanks for all the responses.
I have a ProCraft 215 Combo with a 225EFI on it, the prop says Tempest II and is a 3 blade design, stamped 23P on it. I can not get the engine to rev past 5300 - 5400 RPM which is about 56 - 57 MPH on GPS. Is this a normal speed for this boat?
Also under WOT at these speeds should you be able to trim out your motor to a point where the boat looses speed. Mine does not seem to be able to trim past a certain point - at 5300 RPM i had the motor trimmed up as far as it would allow me, it wont raise any higher - is this nomal?
