I have purchased a Century Coronado Cardel 1984. The engine is a chrysler 440 330 hp. Compressions are all 135 range. My question is what is the max rpm for the boat and motor? I can only obtain at full throttle 3500 rpm and 35 mph(verified by GPS). It has a Federal 14 in 16 pitch prop. Seems to me the boat should preform at higher speeds and rpm's than that? Prop looks to be in good shape, no dings or scars. Thanks Matt
