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
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.
Electrolysis can also be caused by "stray currents"
due to a fault in an electrical item, even though
correctly grounded. Sea Ray
boat with an isolation transformer which isolates
the boat from the dockside electrical system.
