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.
Before selecting a bottom paint, talk with
other boaters and an authorized MasterCraft
dealer’s service department to determine the
product that works best in the area. Many lo-
cal variables may also affect the selection of
paint. Be sure to follow the paint manufac-
turer’s directions exactly.
Be sure all fasteners used are ap-
proved and rated for marine 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
injury!
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) 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 the 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 guidance 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.
Boats operated continuously in salt water should be equipped with the closed
cooling system to preserve engine life.
Stainless Steel and Chrome
Stainless steel and chrome-plated parts are not totally resistant to corrosion. 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.
