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 12-volt
accessories through individual circuit breakers
located in the 12-volt switch panels. 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 accessories 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 wet cell marine batteries. Do not attempt to
use gel cell, absorbed wet mat or other non wet
cell batteries. The engine charging system is not
designed to recharge these batteries which could
cause unusually short battery life, engine starting
problems and damage to the DC charging system.
You should also not mix the size or brand of wet
cell 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 the 12-volt accessory panel. The
battery 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
power by battery 2. Battery 1 will be isolated and
in reserve. Battery 2 will then be charged by the
alternator.
When the selector switch is on 1 & 2, the batter-
ies are connected in parallel so the engine and
12-volt system will be supplied power by both
batteries. Both batteries will be charged by the
alternator. The 1 & 2 position should only be used
when starting the engine, as this requires extra
