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 conductive 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 brackish 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-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.
Note:
Damage due to
CORROSION is not
covered under warranty!
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 recom-
mended application.
MARINE GROWTH
If accelerated marine growth is a
problem in your area, an anti-foul-
ing 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 se-
lection 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!
