Outboard boat engine (200HP to 400HP) with joystick piloting
Engine Serial Numbers: 2B022645-2B174772
Actuator Serial Numbers: 000716-000924
What are the defects?
The steering actuator may be missing the two screws that are intended to retain the internal sensor magnet. The absence of those screws permits the magnet to move and this can result in a false position value being recorded.
What are the hazards?
Potential loss of steering control, which may pose a hazard to the driver or other vessels.
What should consumers do?
Stop using the boat and have it inspected by a Mercury dealer who will check whether the engine steering actuator is defective and, if so, replace it.
