The 12 volt direct current (DC) electrical system
derives its power from the batteries, which are kept
charged by an engine-driven alternator and/or AC
converter. The battery voltage is indicated by the
voltmeters on the main distribution panel and control
station instrument panel. Each battery bank can be
checked with the battery voltage test switch only
on the salon DC distribution panel. The batteries
supply power to the circuit breakers on the main
DC breaker panel in the engine room. This panel
contains the breakers which supply power to the
control station breaker panel and salon DC
distribution panel. The 12 volt dash electronics fuse
panel is protected by the , ELECTRONICS breaker
on the main DC breaker panel in the engine room.
The negative terminal of each bank of batteries
connects to the main DC negative bus which in
turn connects to the negative ground studs of the
propulsion engines and the generator. This
"negative ground system" is the approved system
for marine DC electrical systems.

The batteries in your boat have been selected for
their ability to furnish starting power based on engine
and generator starting requirements as well as their
ability to supply power to the DC system.
The following table describes the recommended
marine cranking batteries to install in your boat.

The main engine cranking batteries consist of three
(3) 12 volt battery for each engine connected in
parallel and if the boat is equipped with the optional
bow thruster, there are two (2) Group 31, 12 volt
marine batteries connected in series dedicated to
its operation. The generator utilizes the port bank
for cranking as well.
Recommended batteries are available through your
