hello Jacob

What prop do you have on the boat now? If your rpms at 'wide open throttle' are low it usually means you are over-pitched. ie....if you have a 21" pitch prop then drop to a 19" pitch prop. That will increase your WOT rpms by about 4-500 and should put you right in the acceptable range for your motor.

I'm not sure what prop would have originally been supplied with your boat. Perhaps someone else here with a similar model can answer that one.

I believe the recommended WOT rpm range is 4200 - 4600 for your 5.7L. If you are running at 4200 rpm now, i'm guessing you have a 21" pitch which means you could likely drop to a 19" pitch (400 rpm increase with the change) and get a slight performance improvement.
