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.
One anode is installed on the bottom of the transom bracket
assembly and the other anode is located on the water intake
housing.
