Look at the anti-ventilation plates while the boat is running up on plane. The tops of them should be visible and not underwater. It is a trial and error procedure, but go ahead and raise the motors 3 holes up if you can, then try it out. You may have to drop back one hole if the props catch air in tight turns.
