I have a 2002 70hp johnson motor 4 stroke that the alarm is sounding. No lights are lite up on the console that would indicate a problem! We cut it off once the alarm sounded the motor was not hot no smells. We waited a few hours cut it back on and it seems to run fine but the alarm sounds and stays on when you know the motor is not even warm. No lights say lite up on the console. Water is pumping out the motor and again seems to run fine. Does anyone know what could cause this? We let it set over night and started it up the alarm stayed on just as soon as you turn the key and stays on no beeps just a continoues alarm sound. Thanks in advance for your help or ideas!
