Maintaining Ground Circuit Continuity

The transom assembly and sterndrive are equipped with a ground wire circuit to ensure good electrical continuity between the
engine, transom assembly, and sterndrive components. Good continuity is essential for the anode and the MerCathode system
to function effectively.
Inspect all ground circuit components for loose connections and broken or fraying wires.
Models equipped with a separate ground wire must have the wire connected between the engine flywheel housing and the
transom plate.
