  • DF 150 AP buzzing sound

    Hi all, I inadvertently left the power on while my boat was on its mooring for two weeks. I only noticed when I returned to the boat and noticed a slight buzzing sound coming from the motor? The motor is a DF150AP 2019.

    Any idea what the buzzing sound is and will it have done any long term damage?

    The motor started instantly and so far runs beautifully.

    any advice would be appreciated

      Power on key off and kill cord removed.
      Motor tilted fully up.

        Probably the servo for the FBW controls. They always hum a bit whenever there is power to the engine. Designed to run for a long time.

        As to whether the slightly louder noise now is a concern, I cannot say.

          Thanks for the update. I’ll make sure it’s turned off in future
