What is the purpose of the Corrosion Control Anode?
Your outboard has control anodes at different locations. An anode helps protect the outboard against galvanic corrosion by sacrificing its metal to be slowly eroded away, instead of the outboard metals. Each anode requires periodic inspection especially in saltwater applications, 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 its effectiveness.
