Is the water coming out my outboard supposed to be hot?
It should be warm but not super hot. The water coming from the engine should be warm also. When it’s warm you know the water is pulling heat out of the engine to keep it cool like it should.
What causes an outboard engine to overheat?
The most common cause of outboard motor overheating is water pump failure. Lack of raw water flow and lack of fresh water can cause water pump failure. Lack of fresh water can be noted if there is a large increase in temperature between the inlet and and outlet of the heat exchanger.
What happens when outboard overheats?
The cooling system keeps the oil temperature down so the oil can lubricate the internal parts of the engine. Overheating ruins the lubrication and the metals parts start melting and sticking together. Or they just break apart with a big bang.

Why does my water pump keep overheating?
Impeller The impeller, the device used to pressure the water into the bottom of the powerhead, is a common cause of overheating. A corroded impeller will no longer allow the water pump to function properly. It can also occasionally shed some blades, in which case tracing the water flow is recommended to find all the pieces.
When to replace the thermostat on an outboard motor?
If it becomes obvious that your thermostat has failed and the engine is not warming enough to maintain a satisfactory starting temperature, replace the thermostat immediately as running the outboard without a functioning thermostat will ruin the powerhead.
What to do if your car overheats after replacing water pump?
The engine doesn’t overheat and it seems like fluid is coming out of the radiator c If coolant has to be added more than once per year, there is a leak. To find the leak that exists in your case, and get the required repair estimated, please request an engine cooling system leak diagnostic and the…
What causes a water heat exchanger to overheat?
Generally, if it is not a problem with lack of raw water flow or fresh water, the heat exchanger will be the cause. The impeller, the device used to pressure the water into the bottom of the powerhead, is a common cause of overheating.
