Mercury - Quicksilver Aluminum Anode Kit Corrosion Protection Series Aluminum Finish 8M6007989. Overview. Any boater who spends time around a stern drive knows that the real work often happens where you cannot see it.

It protects your boat long before you ever feel the effects. The Mercury Marine part number 8M60079
