Corrosion Control Anode - Mercury 225 Pro XS User Manual

Corrosion Control Anode

Avoid corrosion damage. Mercury Marine recommends using anodes
sold through Mercury Precision Parts only. Some other manufacturers of
aluminum anodes use alloys that are insufficiently pure to adequately
protect critical drive components for the duration of the anodes' expected
life.
Anodes help protect the power package against galvanic corrosion by
sacrificing its metal to be slowly eroded instead of other metals.
This model has three corrosion control anodes—two above and one below
the anti‑ventilation plate. A fourth anode is located on the bottom of the
clamp/swivel bracket assembly.
a
a - Corrosion control anodes (three on gearcase)
b - Corrosion control anode (one on clamp/swivel bracket)
All anodes require periodic inspection, especially in salt water (refer to the
Inspection and Maintenance Schedule). Replace any anodes before they
are 50% corroded. Never paint or apply protective coating on the anode,
as effectiveness of the anode will be reduced.
