Hello, I am having trouble with my boat when it is under a load. I recently changed engines since my old one was not in the best of shape. When just running a hose to the pick-up pump and in neutral I can throttle up to 6k rpms no problem. But when I put it in the water and in gear I can cruise around in the 5mph zone no problem then once you throttle up and can't even get out of it's own wake. Any ideas? I think it may be related to a transmission problem or on a rare mishap the flywheel... :facepalm:
