Zinc anodes generally require replacement
about once a year. (In salt water areas, replace
every six (6) months). The need to replace anodes
more frequently may indicate a stray current
problem within the boat or at the slip or mooring. If
zinc anodes do not need replacing after one year,
they may not be providing proper protection. Loose
anodes or low-grade zinc may be the problem.
!
CAUTION
Replace zinc anodes if they are corroded 50% or more.
When an AC shore power system is connected to
the boat, the underwater metal fittings will, in effect,
be connected through the water to grounded metals
ashore. The zincs will be consumed at a faster rate
unless the marina maintains a protective system
to prevent this. In this case, hanging a zinc in the
water bonded to the metal outlet box on the dock
will reduce zinc loss on the boat. DO NOT connect
this zinc to the boat's ground system.
It is extremely important that all electrically
operated DC equipment and accessories be
wired so that the ground polarity of each device
is the same as that of the battery. Sea Ray
have a negative ground system, which is the
recommended practice throughout the marine
industry. All metal items (fuel tanks, underwater
gear, etc.) in the boat are connected to the zinc
anode by the green bonding wire.
!
CAUTION
Never disconnect the green wire (safety ground) from
the engine terminal.
Electrolytic corrosion can also be caused by "stray
currents" due to a fault in an electrical item, even
though correctly grounded.
NOTICE
DO NOT PAINT BETWEEN THE ZINC AND THE
METAL IT CONTACTS, AND DO NOT PAINT OVER
THE ZINC.
