Corrosion
Galvanic Corrosion
Galvanic corrosion (electrolysis) to the
boat is the decompositoin of metal due to
the effects of electrolytic action. When two
dissimilar metals are immersed in a conduc-
tive fluid (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, 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 pre-
vent damage to those metal parts coming in
contact with the water. The zinc is, by de-
sign, 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.
Salt Water Corrosion
Your boat has been designed for operation in fresh water. If you are operating temporarily in salt, polluted or
brackish water, you will need to flush with fresh water. The entire engine cooling system should be flushed with
fresh water for at least 10 minutes after each use. If you operate continuously in salt water, the closed-cooling
system option is the recommended application.
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 product
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.
Note: Damage due to corrosion is not covered under warranty!
CORROSION
14-1
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!
