ELECTRICAL SYSTEM
6.1 General
Your Everglades is equipped with a 12-volt DC
electrical system that draws current from two
onboard batteries. The engine charging system
is designed for 12-volt lead acid wet cell marine
batteries that require similar maintenance as
those found in automobiles.
All wires in the electrical system are color coded to
make identifying circuits easier. Wiring schemat-
ics have been included with this manual to aid in
following an individual circuit of the boat.
6.2 Boat 12 Volt DC System Overview
The 12-volt system is a standard marine system.
There are two batteries located below the port and
starboard stern seats. They are controlled by a
battery selector switch and charged by the engine.
Most 12-volt power is distributed to the acces-
sories through individual fuses located in panels
behind the helm. A main helm circuit breaker
located in the battery switch panel protects the
system from an overload. Other circuit breakers
located in the battery switch panel protect the
circuits for the automatic oat switch for the bilge
pump and the stereo memory. Most 12-volt ac-
cessories are operated directly by switches in the
helm accessory switch panel or separate accessory
switch panels.
Main breakers or fuses located on the engine
protect the ignition systems and gauges. Yamaha
engine electrical circuits are protected by fuses
located in a fuse panel on the side of the engine.
The fuse panel is equipped with a spare fuse for
each circuit. Always replace fuses with the fuse
specied by Yamaha or your engine manufacturer.
Refer to the engine owner’s manual for more
information on the fuses, fuse panels or circuit
breakers on your engines.
PROPER FUSE OR BREAKER PROTECTION MUST BE PROVIDED
FOR ALL 12-VOLT EQUIPMENT ADDED. DO NOT OVERLOAD
THE ACCESSORY CIRCUIT BREAKERS OR OTHER CIRCUITRY
THROUGH ADDITIONAL 12-VOLT EQUIPMENT.

6.3 Batteries and Battery Switch
The DC electrical system on your boat is designed
for marine batteries. Some engine charging
systems have specic battery requirements and
will not operate properly with batteries of the
improper type, size or amperage rating. Battery
selection is particularly important with 350 horse
power Yamaha V8 engines. We recommend using
only Optima AGM batteries of the proper size and
amperage rating for boats equipped with these
engines. Refer to the engine Owner’s Manual for
battery specications.
Do not attempt to use gel cell or other batteries
not recommended by the engine manufacturer.
The engine charging system may not be designed
to recharge these batteries which could cause
unusually short battery life, engine starting prob-
lems and damage to the DC charging system.
You should also not mix the type, size or brand of
batteries. Always consult your Everglades dealer
before changing the type of batteries in your boat.
Your boat has provision for two batteries. These
batteries should be of the size and capacity recom-
mended by the manufacturer of your engine. See
the engine owner’s manual. These specications
should be considered to be the minimum size bat-
tery required. Consider increasing the capacity
of the battery if you will be trolling, drift shing
or have extensive electronics onboard. Larger
batteries will give you additional capacity to oper-
ate the baitwell, washdown and electronics at low
speed when the charging system output from the
engine is minimal.
The battery selector switch is located in a panel
below the starboard stern seat. The switch feeds
the engine and 12-volt accessory panel. The bat-
tery switch is a dual circuit switch that has four
positions, OFF, 1, 2 and 1 & 2 (both batteries).
12-volt power can be supplied by either battery
1 or battery 2 separately or by both batteries
simultaneously. The selector switch also directs
the charging current when the engine is operating.
For example: When the switch is on battery 1,
the engine and 12-volt system will be supplied
power by battery 1. Battery 2 will be isolated
and in reserve. Battery 1 will be charged by the
alternator. When the selector switch is on battery
2, the engine and 12-volt system will be supplied
