NOTE: DAMAGE DUE TO CORROSION IS NOT COVERED UNDER
WARRANTY!
GALVANIC CORROSION
Galvanic corrosion (electrolysis) to the boat is the decomposition
of metal due to the effects of electrolytic action. When two (2) dis-
similar 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 oper-
ated in salt, polluted or brackish waters, even temporarily, the boat
should be equipped with a transom-mounted zinc anode to prevent
damage to those metal parts coming in contact with salt water.
The zinc is, by design, self-sacrificing. It is slowly eroded away by
electrolytic action and requires periodic inspection for deterioration.
When the zinc 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 Saltwater Series boats come equipped with the zinc
anode. For fresh water boats that may be operated in polluted or
brackish water, an authorized MasterCraft dealer can provide guid-
ance in securing and installing a zinc anode for protection.
SALT WATER CORROSION
The boat has been designed for operation in fresh water unless it is a
model in the MasterCraft Saltwater Series. 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.
