I just bought a 91' Chaparral 20' V hull with a 5.7L in it. The boat was in great shape all the way around and the motor seemed good. However when I get it on plane I can't seem to rev past 3500-3700 max even on a smooth calm day. My last run at 3600 rpm I was coming up on 50-52 mph or so. I believe the max rating is between 4200-4600 or so. Am I wrong thinking that it would be running well past 60 if it were to rev all the way out? Possibly the gear ratio has been changed? The current prop is a 13 7/8" 21P. I was thinking the motor should pull this fine and come out of the hole good to, but am I way off? It doesn't jump out of the hole real well either. It will pull a skier up ok, but I would like more snap for sure. Before I jump to the conclusion that I need a prop does anyone have any other Ideas? Thanks
