I have an early 1980's 3.6hp Mercury. I took it out on the bay by our house for a little toot and found the motor to get very warm. I took the lower end off and replaced the impeller, the 0-ring at the top of the drive shaft and the rubber washer on top of the water pump. I also replaced the rubber grommet and the rubber spacer at the top of the water tube. I blew air through the block and it appeared to be free. I made a new gasket for between the motor and adapter plate at the old one was ruined and a new one from Mercury was no longer available. My motor still seems to be running hot. I am hoping someone has a suggestion that will get me running cool again.
Thanks
