1. DC Electrical System
The DC electrical system is powered by either one or two batteries, and are kept charged by the
engine driven alternator. The battery voltage is indicated by the voltmeter screen located on the
SmartCraft
TM
tachometer, or on the optional Vessel View.
2. Batteries
Refer to your engine owner’s manual for exact batteries requirements. All batteries in a battery bank
should be of the same type, age, and rating.
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 storage hatch.
Depending on the engine type dictates the number of batteries on your boat. On a boat that has an L6
Verado, there are two batteries; on all other engines, there is only a single battery. The battery can be
installed or removed by loosening the strap and removing the lid on the battery box. They should
always be installed and secured with the battery box installed on your boat. This will ensure that the
battery will not move around while the boat is underway.
4. Battery Selector Switches
Your vessel is equipped with a battery switch to control the delivery of DC power from the batteries.
The battery switch is located in the aft storage tub.
Non - L6 Engine Boat
On a non - L6 engine boat
,
there is a single battery switch that controls a single battery. The battery
switch is located on a panel located under the center aft seat hatch at the L - lounge. When you turn
the battery switch to the ON position, power is provided from the battery to the entire boat. To turn
on power, rotate the switch clockwise 90 degrees to the ON position.
L6 Engine Boat
On a L6 engine boat, 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.
NOTE: Never operate or turn off the battery switch when the engine is running as it may cause
damage to electronic components on the boat. Always operate the switch with the engine and
accessories off.
Never use an open flame in the battery storage area. Avoid
striking sparks in the battery area.
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.
