IMPORTANT: Mercury Marine recommends installing an Anti‑Corrosion
Kit. If the boat is equipped with stainless steel after planes, a large anode
should be installed on each to handle the increased galvanic corrosion
potential.
Replace sacrificial anodes if eroded 50% or more.
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.
a - VI SSM ‑ An anode is
mounted to the underside
of the anti‑ventilation plate
and is retained by two nuts.
b - VI SSM ‑ There are
additional anodes on the
trim cylinder pins.
