Corrosion

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 ef-
fects of electrolytic action. When two dissimilar
metals are immersed in a conductive fl uid (salt
water), an electric current is produced, much like
the action of a battery. As the current fl ows, it
takes with it tiny bits of the softer metal. If left un-
checked, a great deal of damage could occur.
If you operate in salt, polluted or brack-
ish waters, your boat should be equipped with a
transom-mounted zinc anode to prevent damage
to those metal parts coming in contact with the
water. The zinc is, by design, self-sacrifi cing. It
is slowly eroded away by electrolytic action and
requires periodic inspection for deterioration.
If the zinc shows extreme erosion, it must
be replaced to continue protection, or damage to
other metal parts may result.
Salt Water Corrosion
Your boat has been designed for operation in fresh water unless it has specifi cally been designed as part of the
Saltwater Series. If you are operating a fresh-water model temporarily in salt, polluted or brackish water, you will need
to fl ush with fresh water. The entire engine cooling system should be fl ushed with fresh water for at least ten minutes
after each use in such waters.
Boats operated continuously in salt water should be equipped with the closed cooling system to preserve
engine life.
Marine Growth
If accelerated marine growth is a problem in your area, an anti-fouling bottom paint may be necessary to slow
growth while protecting your gel coat.
Before selecting a bottom paint, talk with other boaters and your MasterCraft dealer to determine the prod-
uct that works best in your area. Many local variables can affect the selection of paint. Be sure to follow the paint
manufacturer’s directions exactly.
Be sure that all fasteners you use are approved and rated for marine use. Most fasteners used on MasterCraft boats
are stainless steel or specially coated to resist corrosion.
Use of improper parts can cause component or engine failure, which may result in serious injury or death!
