1. DC Electrical System
The DC electrical system is powered by two baeries, they are kept charged by the engine driven
alternator. The baery voltage is indicated by the voltmeter screen located on the SmartCra®
tachometer.
2. Baeries
Refer to your engine owner’s manual for exact baeries requirements. All baeries in a baery bank
should be of the same type, age, and rang.
To remove the baery cables:
1. Turn o all items drawing power from the baery.
2. Turn the baery switch to the OFF posion.
3. Remove the negave cable rst, then the posive cable.
4. To replace the cables, install the posive cable rst, then the negave cable.
3. Baery Boxes
The baeries are located in the a bilge and can be accessed through the cockpit storage hatch. They
can be installed or removed by loosening the strap and removing the lid on the baery box. The
baeries should always be installed and secured within the baery boxes on your boat. This will
ensure that the baery will not move around while the boat is underway.
4. Baery Selector Switch
Your vessel is equipped with a baery switch, located in the baery panel tub on the starboard side
on the a L-lounge, to control the delivery of DC power from the baeries. There is a single baery
switch that controls two isolated baery banks. When you turn the baery switch to the ON posion,
power is provided from both the port engine baery and the starboard house baery. The baery
switch also has the ability to combine baery banks for emergency starng. To turn on power to the
boat, rotate the switch clockwise 90 degrees to the ON posion. To ulize both baery banks for
emergency starng, push the switch in and rotate clockwise 45 degrees.
Never use an open ame in the baery storage area. Avoid
striking sparks in the baery area.
Always disconnect the baery before doing any work on the
electrical system. Never turn o the baery switches or
disconnect the baery cables while the engines are running.
The bilge pumps and stereo memory sll draw power from
the baeries, even if the switches are set to OFF. This is
especially important for the bilge pumps, so that they can
operate anyme excess uid accumulates in the bilge,
which can occur when the boat is docked and unaended.
Never work on the electrical system while the system is
energized. Never leave the cra unaended with the
electrical system energized.
