GALVANIC CORROSION
NOTE: DAMAGE DUE TO CORROSION IS NOT COVERED UNDER
WARRANTY!
Galvanic corrosion (electrolysis) is the decomposition of metal
due to the eects of electrolytic action. When two (2) dissimilar
metals are immersed in a conductive fluid (e.g., salt water), an
electric current is produced, much like the action of a battery. As
the current flows, it takes with it tiny bits of the softer metal. If
left unchecked, severe damage may occur over time. If the boat
is operated in salt, polluted or brackish waters, even temporarily,
the boat should be equipped with a transom-mounted aluminum
anodes to prevent damage to those metal parts coming in contact
with salt water.
The aluminum is, by design, self-sacrificing. It is slowly eroded
away by electrolytic action and requires periodic inspection for
deterioration.
When the aluminum has eroded to approximately one-half (1/2)
of its original size, it must be replaced to continue protection, or
damage to other metal parts may result.
MasterCraft boats optioned with a saltwater package come
equipped with aluminum anodes. For fresh water boats that
may be temporarily operated in polluted or brackish water, an
authorized MasterCraft dealer can assist in installing proper
corrosion protection systems including sacrificial anodes and fresh
water flush kits.

SALT WATER CORROSION
MasterCraft boats have been designed for operation in fresh
water unless equipped with the Salt Water Package. If operating a
fresh-water model temporarily in salt, polluted or brackish water,
thoroughly flush the boat with fresh water as soon as possible
afterward. The entire engine cooling system should be flushed
with fresh water for at least ten (10) minutes after each use in such
waters. Do not operate boats continuously in saltwater unless
equipped with a closed cooling system to preserve engine life.
