Corrosion Control Anode - Mercury 75 Operation Maintenance Warranty Installation Manual

Corrosion Control Anode

Your outboard has corrosion control anodes at different locations. An anode
helps protect the outboard against galvanic corrosion by sacrificing its metal to
be slowly corroded instead of the outboard metals.
Each anode requires periodic inspection, especially in saltwater which will
accelerate the erosion. To maintain this corrosion protection, always replace
the anode before it is completely eroded. Never paint or apply a protective
coating on the anode as this will reduce effectiveness of the anode.
The gearcase has two corrosion control anodes, one on each side. A third
anode is installed on the bottom of the transom bracket assembly.
