1996 Mercury 2 stroke/ 4 cyl C40ELPTO - Suspect False Overheat Warnings
Getting various warning beeps. Usually the long beep that is an overheat. (See other posts…continuing saga).
Replaced the impeller - no signs of overheat, despite several past overheat warnings. Strong flow out the pisser….always has been. Motor does not have a thermostat. Was not built with a thermostat. Ran the motor for an hour after the impeller install and shot the top plug with IR thermometer - 108F. Ran the motor several hours, got a chirp-beep - top plug 113F. Subsequently, my wife ran it for over an hour and got a long beep. She felt the engine cover - it was not warm.
When we first turn the key on we either get no beep, a short beep, or one long lasting beep.
I am guessing the warning system is bad. Cannot find anything about the warning system in the OEM repair manual.
Anyone have a fix for this?
