Quicksilver 755CR — Electrical Systems
1. DC Electrical System
The DC electrical system is powered by two batteries, they are kept charged by the engine driven
alternator. The battery voltage is indicated by the voltmeter screen located on the SmartCraft®
tachometer, or on the optional GPS with Vessel Link.

2. Batteries

Quicksilver® recommends AGM type starting or a deep cycle battery for you boat. The battery must
meet the minimum capacity required by the engine manufacturer. Refer to your engine owner's
manual for exact battery requirements.
To remove the battery cables:
1. Turn off all items drawing power from the battery.
2. Turn the battery switch to the OFF position.
3. Remove the negative cable first, then the positive cable.
4. To replace the cables, install the positive cable first, then the negative cable.

3. Battery Boxes

The batteries are located in the aft 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 battery box. The
batteries should always be installed and secured within the battery boxes on your boat. This will
ensure that the battery will not move around while the boat is underway.
Never use an open flame in the battery storage area. Avoid
striking sparks in the battery area.
4. Battery Selector Switch
Your vessel is equipped with a battery switch, located in the battery panel tub on the starboard side
on the aft L-lounge, to control the delivery of DC power from the batteries. There is a single battery
switch that controls two isolated battery banks. When you turn the battery switch to the ON position,
power is provided from both the port engine battery and the starboard house battery. The battery
switch also has the ability to combine battery banks for emergency starting. To turn on power to the
boat, rotate the switch clockwise 90 degrees to the ON position. To utilize both battery banks for
emergency starting, push the switch in and rotate clockwise 45 degrees.
The bilge pumps draw power from the batteries, even if the
switches are set to OFF. This is especially important so that
they can operate anytime excess fluid accumulates in the
bilge, which can occur when the boat is docked and
unattended.
