Electrical Systems

Section 5

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

located in the control console, just inside the console

door.

The main power and negative cables from the out-

board engine route through the splash-well boot and

connect to this power circuit through a main two-posi-

tion, heavy-duty terminal strip located near the tran-

som. The 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.
