Re: Over Heating!!!
The obvious path would be to rebuild the water pump and replace the impeller, secondly, I would take the head and have it resurfaced since the motor overheated. This will also give a light to the extent of the damage if the motor overheated and what to do from there. Finally, I would put the resurface head and replace the gasket. <br /><br />Now comes the test. In a tank or a 55 gallon drum if possible I would start the motor to see what happens. Water should come from the exhaust relief in the middle of the leg. <br /><br />After operating for a while in the tank I would put my hand already wet in water on top of the head to check for overheating. If you could keep your hand in the head for a brief moment all is ok. <br /><br />The next path would be to run the motor mounted in the boat at a lake were you test run the motor.
