Owner’s/Operator’s Manual
Following is a list which specifies the required electrical current to operate a selection
of items:
These items are only examples and the actual electric current usage (amperage)
may differ between manufacturers. The power requirement is usually specified on the
electrical equipment. Refer to the manufacturers’ specification plate. Monitor the
ammeter when using electrical equipment; amperage draw must not exceed 30
Amps.
ANTICORROSION SYSTEM
Electrolysis
When connected to shore power your boat is earth grounded. There is a complete
electrical circuit from the shore power, through the grounded metal parts of your
craft, to the water. While this circuit is designed to provide protection against
hazardous shocks, it also creates an electrolytic current which causes the
decomposition of all submerged metal.
Sacrificial Zinc Anodes
1. Sacrificial zinc anodes, installed by the dealer or the engine manufacturer,
protect the hardware that is exposed to the water. Electrolysis attacks the
softest metals first. Because zinc is a relatively soft metal, it will decompose
before harder metals. Check the anodes periodically, and have them replaced
as required. See your CROWNLINE dealer for parts and service. Refer to
your Engine Operation and Maintenance Manual for the recommended
anticorrosion requirements.
2. A ground circuit isolator will prevent the flow of relatively low electrolytic
currents, but provide a path for catastrophic short-circuit currents which are
sufficient to activate circuit breakers.
