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 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 boats optioned with a saltwater package come
equipped with a zinc anode. For fresh water boats that may be tem-
porarily operated in polluted or brackish water, an authorized Mas-
terCraft dealer can assist in installing proper corrosion protection
systems including sacrificial anodes and fresh water flush kits.
