You don't say how old the motor is, but you might also check the riser portion of your manifold. A common problem with engines that run in salt water, the riser begins to rust on the inside and the rust flakes off and blocks the water from exiting the engine causing overheating. The more common cause is as Cat said, vanes of the impeller break and usually lodge in the outlet portion of the pump housing with the Bravo II and III packages. If the motor is cooled via a heat exchanger, the heat exchanger may need to be cleaned with a chemical agent to boil the scale out of the exchanger.
