Why is my water pump overheating?
If the pump loses prime, then the water inside of the pump casing can get extremely hot (due to the friction of the impeller) and eventually turn to steam. The most likely culprits to cause a pump to lose prime are a small air leak in to suction line or a leaking shaft seal.
Why is my boat motor running hot?
The most common cause of outboard motor overheating is water pump failure. Water pump failure can also be caused by a defective heat exchanger, though this is harder to check. Generally, if it is not a problem with lack of raw water flow or fresh water, the heat exchanger will be the cause.

While electrically related failures are by far the most common cause for pump overheating, as we will discuss at length, there is also the potential for a friction fire to develop if a pump is starved for water.
What problems can leaking Waterpump cause?
A faulty water pump can cause a number of problems: Your engine overheats: If the water pump fails, your engine likely won’t get adequate coolant circulation, which will make it overheat.
