Corrosion Prevention

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.

If the zinc shows extreme erosion, 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.

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 de-
partment to determine the product that works best in the area. Many local variables may also affect the selec-
tion of paint. Be sure to follow the paint manufacturer’s directions exactly.

Be sure all fasteners used 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 may cause component or engine failure. Such failure may result in death or
serious injury!

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.
