No, none of the motors need to run but it's best to help replinish the Bat doing the workDoes the boat need both engines running to retrieve?
If your only using the remote handheld control then you have an issue with it. On page 21 of the manual it can the the hand control or the remote station control.If it's an anchor windless (I had same model) then most likely its the relay which is normally close to the windless. Can also be the helm switch has issues or bad connection
