The MerCathode system provides automatic protection against galvanic corrosion. It is a solid-state device that operates off a boat's 12-volt battery and provides protection by impressing a reverse blocking current that stops the destructive flow of galvanic currents. If your power package does not come already equipped with a MerCathode system, Mercury strongly recommends that you install one, particularly if your boat is equipped with a stainless steel propeller or other submerged stainless steel hardware. Anode/reference electrode unit mounts in place of zinc anode under the gimbal housing, eliminating the need to drill holes through the transom. Blue controller is mounted inside the boat.
