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 eroded instead of the outboard metals.
Each anode requires periodic inspection, especially in salt water 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.
