I just put in a remanufactured 460 king cobra in my 28' bayliner cirra. I can tell the prop is not right because a 3500 rpm the boat seems to go nowhere, and can't seem to plane out. Even with raising and lowering the outdrive, and trim tabs. Is there a formula for figuring out the right pitch? Boats my size and weight, were passing me like I was standing still.
