Hello, my name is***** will assist you.

Do you have joystick controls on the boat?

Ok, the code is for the joystick control. It is telling you that the thrust vector module of the stick is not functioning. There was a fix campaign on these to update the software to correct any false code from going off. You will need to call your closes Mercruiser dealer and have the engine serial number handy so that they can run it through the dealer site and see if this campaign was ever done to your boat. Hopefully getting the latest software will correct the issue with the joystick.
