    4jh80 wont start

    Update: Pulled the relay and tested it as good. Tested voltage at the relay harness and the hot leg of the relay circuit is only showing 0.8v with the engine ON and when connected to the battery negative. The relay energizer legs show the correct voltage for On and Start which is consistent...

    4jh80 wont start

    2018 4jh80 wont start. We have ultraflex throttle controls at the helm which show no errors. Powers up but when the start button is pressed, all I get is the tiniest of clicks coming from somewhere in the motor (probably some kind of solenoid).

Unfortunately, I sheared off one of the two bolts while removing the thermostat cover so I will have to deal with that but...

    BF20d overheating

    I have a 2018-ish BF20d with power tilt and remote that is throwing an overheating buzzer and red light on the throttle controls after I throttle up for a few minutes. The alarm has not come on at lower speeds for 20+ minutes. If the alarm sounds, it drops the RPMs down. If I shut off the engine...
