NOTE: DAMAGE DUE TO CORROSION IS NOT COV-
ERED 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 uid (e.g., salt water), an
electric current is produced, much like the action of a battery. As the
current ows, it takes with it tiny bits of the softer metal. If left un-
checked, 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 the water.
The zinc is, by design, self-sacricing. 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 con-
tinue 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-wa-
ter model temporarily in salt, polluted or brackish water, thoroughly
ush the boat with fresh water as soon as possible afterward. The
entire engine cooling system should be ushed with fresh water for at
least ten (10) 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 the area in which the
boat will generally be operated, an anti-fouling bottom paint may be
necessary to slow growth while protecting the gel coat.
co r ros i o n pr ev enti o n
Before selecting a bottom paint, talk with other boaters and an au-
thorized MasterCraft dealer’s service department to determine the
product that works best in the area. Many local variables may also
affect the selection of paint. Be sure to follow the paint manufacturer’s
directions exactly.
Be sure all fasteners used are approved and rated for ma-
rine use. Most fasteners used on MasterCraft boats are
stainless steel or specially coated to resist corrosion.
Use of improper parts may cause component or engine
failure. Such failure may result in death or serious in-
jury!
Stainless Steel and Chrome
Stainless steel and chrome-plated parts are not totally resistant to cor-
rosion. Occasional cleaning and polishing with a marine chrome-and-
stainless polish will maintain and extend the life of these parts. In salt
water areas, it is imperative that you thoroughly rinse all hardware with
fresh water and apply a light coating of protective oil to enhance the
appearance after each use.
Exposure to salt water will cause corrosion leading to
significant damage to stainless steel and chrome parts.
Failure to thoroughly rinse salt water from all hardware,
and to apply protective oil after each exposure to salt
water, will accelerate the corrosion of hardware and will
void your warranty.
