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).
Heat exchangers will get pieces of impeller stuck in it when the impeller goes back. It is recommended to check to see if risers are full of rust also. add a comment
