My alarm gives a constant tone after around 15-20 minutes at idle in gear, water temp gague is working, and seems to be alright, water temp reads around 120 at idle and goes up to 145 at speed, but the alarm goes off at idle. I shut off the engine lift the motor and no fouling in the water intake.. drop the motor and restart and no tone. the impeller is pumping water in a constant flow (has been replaced recently). Sounds like an electrical issue in the alarm system, but I dont know where to begin. Advice?
