Without having specifics like the engine type and size it is impossible to give you a quick boat repair fix. One thing you should definitely check on is the manifold. If the outflow of cooling water is impeded your motor will get hot at the higher speeds and eventually overheat.

Several things can cause a boat to overheat and need repair: impeller going bad or was installed incorrectly, hoses installed backwards (a common occurrence) which can cause water to be pushed rather than sucked in, water transfer hose from the drive to the transom plate (check for kinks in hose).
