I have a 1986 Evinrude 9.9 with a new water pump and thermostat. I am getting plenty of water through the pee hole. After it runs for about 15-20 minutes it starts to over heat and steam starts poring out of the small exhaust hole. When I elevate the motor so that water can inter the motor and still view the underwater exhaust, no water was coming through with the exhaust, I have tried blowing 100lbs of air pressure through the pee hole, I took the thermostat plate off and blow air through those holes. This motor has been lightly used in fresh water and there is no corrosion anywhere inside the motor that I could see when I replaced the water pump and the thermostat. Blowing the air did nothing.

Do I have a bad head gasket or something else? HELP Needed !

suggest you check and see if the rubber grommet for the water tube got pinched, and blocking water flow, does not take much water to get a tale tell. is tstat installed correctly.
