Corrosion Control Anode
The outboard has corrosion control anodes at different locations. An anode
helps protect the outboard against galvanic corrosion by sacrificing its metal to
be slowly eroded 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 50% eroded. Never paint or apply a protective coating on
the anode as this will reduce effectiveness of the anode.
