DC Power Distribution
All DC electrical devices and systems in your boat are
controlled and protected by
six
main 12 VDC power
distribution circuits.
Outboard Engine
Main 12 VDC power circuit 1 of 6
provides power for
starting the outboard engine through a battery OFF-
ON switch connected to a Group 24 1000 MCA bat-
tery. The outboard engine battery OFF-ON switch is
properly labeled and is located on or inside the control
console.
The main power and negative battery cables from the
outboard engine route through the splash-well boot
and connect to this power circuit through a main two-
position, heavy-duty terminal strip located near the
transom. This main terminal strip simplifies engine
removal for service or replacement.
Turning the outboard engine battery OFF-ON switch to
the
OFF
position at the end of your mission will cut
power to the outboard engine and its accessories.
