GALVANIC CORROSION
NOTE: DAMAGE DUE TO CORROSION IS NOT COVERED UNDER
WARRANTY!
Galvanic corrosion (electrolysis) is the decomposition of metal due
to the effects 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 dam-
age 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 protec-
tion 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 after-
ward. 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.
