Mercury Quicksliver Mercathode Galvanic Isolator #98869A17 S/S #98869A11

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.
