Outboard Motor Question
Mr. Chuck maybe you can help.
I am looking at buying a used motor. It looks lik an 1988, Evinrude, 25 hp Commercial, 2-stroke. The motor starts and runds great. The water was
flowing strong out of the pee hole. I did notice that the water coming out of the pee hole was very hot. So hot that there was some steam when the
water hit the barrell and it was not comfortable to touch. Is this too hot or normal? Could there be something wrong with the motor.

It shouldn't run that hot ssounds like bad impeller or some water passages plugged,
Sometimes rubber from old impeller breaks off and blocks passage

Impellar
The flow was strong, so I think the impellar is fine. Might be blocked water passages.

take a temperature reading of the exhaust water. It should not be much over warm to slightly warm to the touch. You either have a restriction, which
happens frequently with older two strokes that have been used in the salt, or the impeller is in need of replacement. I have seen them push a good
stream of water out the upper hole but be almost destroyed when you open them up. I replace my impeller every two years as a part of normal
maintence.
Taste the water coming out of the intake to see if there is any salty residue. If it is salt caked, then you can take the motor down or run it in
freshwater for a day or two, but in any case I would replace the impeller if you decide to buy it.

One more thing to check on the Evinrude?s that a lot of people disregard is the thermostat. On the Evenrudes the area around the thermostat is not
very large, salt and sand can build up and the engine runs fine until the throttle is opened up, then the water flow is restricted and the motor
overheats. Under no circumstance do you want to remove the thermostat. It is there for a reason. I replace the thermostat and the water pump at the
same time.
