My buddy run his motor into a beaver dam and plugged the water intake, the alarm sounded and he stopped and unplugged it.
Now when he starts it runs fine for a couple minutes, then cuts out and alarm sounds again, it is pumping lots of water and is not running hot, is it the sensor or something else?
