Quicksilver 875SD — Electrical Systems
1. DC Electrical System
The DC electrical system is powered by two batteries, and are kept charged by the engine driven
alternator or by the battery charger when connected to AC power. The battery voltage is indicated by
the voltmeter screen located on the SmartCraft
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 switches to the OFF position.
3. Remove the negative cable first, then the positive cable.
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 floor 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 Switches
Your vessel is equipped with battery switches to control the delivery of DC power from the batteries.
The battery switches are located on the starboard aft corner of the cockpit behind an access door.
The number of engines and options on your boat determines the number and type of battery
switches.
The bilge pumps and stereo memory still draw power from
the batteries, even if the switches are set to OFF. This is
especially important for the bilge pumps, so that they can
operate anytime excess fluid accumulates in the bilge,
which can occur when the boat is docked and unattended.
Single Engine Boat
On a single engine installation, there is one battery switch that controls two isolated battery banks.
When you turn the battery switch to the ON position, power is provided from both the engine battery
and the 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.
TM
tachometer, or on the optional GPS with Vessel
Always disconnect the battery before doing any work on the
electrical system. Never turn off the battery switches or
disconnect the battery cables while the engines are running.
Never work on the electrical system while the system is
energized. Never leave the craft unattended with the
electrical system energized.
