Inside the Bulkhead
Once a year, spray electrical connections, fuse
panels and antenna bases. Light sockets should be
treated at two- or three-month intervals. Every six
months, treat plumbing connections in the galley
and head areas. Once a year, apply to hinges,
locks and sliding tracks of doors and windows to
keep them properly lubricated and functioning
smoothly.
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 is
rusted shut and needs to be broken apart, it is 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 water 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 saltwater,
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 water 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
requirements on 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 saltwater damage as
described in
Interior/Exterior Care , in this section.
Refer to the propulsion unit operator’s manual for
manufacturer’s saltwater operating
recommendations.
A
WARNING
The vessel does not have ground fault
or galvanic corrosion protection. To
prevent possible shock, drowning or
galvanic corrosion, do not use the
battery charger when the vessel is in the
water.
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.
