On my 73 50hp evinrude I have let it run for several minutes with the muffs on it, I have noticed that the water coming out of the pisser is cold and the motor is just sightly warm. I have to run it with a fast idle. It will not run at slow idle. Could the thermostat be stuck open, and could this be why it will not run at slow idle.<br />I hav noticed that after shutting the motor and the water off that the water coming out of the pisser is just warm, not hot.<br />If it needs a thermostat where is it located.
