Other Areas
Treat hydraulic cylinder shafts for steering and
other operating mechanisms once a month. Spray
the entire engine, including engine mounts, every
six months. Treat the bilge pump housing and
connections plus other items in the bilge area once
every three months. Thru-hull fittings and seacocks
should also be treated every three months. Fuel
line fittings at the fuel tank should be treated every
six months.
CorrosionX is a multi-functional product with
universal application. A good rule of thumb: if it
rusts or corrodes, if it needs lubricating or if it’s
rusted shut and needs to be broken apart, it’s a
potential application. If you have any questions
about CorrosionX, check the manufacturer’s web
site:
http://www.corrosionx.com or
call 800-638-7361.
Corrosion destroys underwater metal parts and can
occur in fresh or salt water. Salt, brackish and
polluted waters will accelerate corrosion.
Galvanic Corrosion
Galvanic corrosion (electrolysis) can result in
serious damage to any metal component of your
Cobalt boat that is in the water. Galvanic corrosion
is the deterioration of metals due to the effects of
electrolytic action. When dissimilar metals are
immersed in a conductive fluid such as salt water,
an electric current is produced, similar to the action
of a battery. The softest of the metals will be the
first to become damaged.
Galvanic corrosion can occur in fresh or salt water,
however, salt, brackish and polluted waters
accelerate galvanic corrosion.
A self-sacrificing anode can be mounted to your
Cobalt boat to help prevent damage to metal
components from galvanic corrosion. The anode
will require frequent inspections. If the anode
shows deterioration of 50% or more, it must be
replaced for continued protection.
Refer to the propulsion unit operator’s manual for
their requirements for galvanic corrosion protection.
Salt Water
Wash the entire boat after each use in salt water. If
you continue to operate in salt water, the entire boat
should be protected against salt water damage as
described in
Interior/Exterior Care
, in this section.
Refer to the propulsion unit operator’s manual for
manufacturer’s salt water operating
recommendations.
NOTICE: Do not paint an anode,
its fasteners or its mounting
surface. Painting will reduce the
anode’s corrosion protection
capabilities. Make sure the
anode’s contact to its mounting
surface is clean and secure.
