I have a '91 Evinrude 70 hp. While out on the lake Saturday, the overheat buzzer came on twice before I unplugged it. I unplugged it because the tell tale pee stream was cool and plentiful. My question is what are the pros/cons to removing the thermostat? On this motor the thermostat and the overheat sensor are just above the top cylinder. I'm thinking of running a test on the lake without the thermostat to see if the buzzer comes on again.
