Battery Inspection - Mercury 200 User Manual

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.
