6.1 Electrical System Overview
Your boat is equipped with a 12 volt DC electrical
system and could be equipped with an optional
120 volt AC battery charging system. The battery
charger draws current from a shore power outlet
at dockside. The DC system draws current from
onboard batteries.
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.
12 Volt DC System
The boat and engine charging systems are de-
signed for 12 volt, lead acid wet cell or absorbed
glass mat (AGM) batteries. Most wet cell batter-
ies will require similar maintenance as those in
automobiles. AGM and some wet cell batteries
are sealed and require no maintenance except
to periodically clean battery tops, terminal posts
and connections.
It is important that you know the type of batteries
in your boat and that the engine charging system
and optional battery charger are set to recharge
these batteries. Charging systems not set to the
proper battery type could cause unusually short
battery life, engine starting problems and damage
to the DC charging systems. You also should not
mix the brand or type of batteries.
The batteries in your boat were installed by the
dealer. They should be of the size and capacity
recommended by the manufacturer of your en-
gine. Labels on the battery cables indicate the
specications for the batteries required to power
the house and engine electrical systems. See the
engine owner’s manual for more information on
battery requirements. These specications should
be considered to be the minimum size battery
required.
Always consult your dealer before changing the
type of batteries in your boat or if you have ques-
tions regarding the batteries.
6.2 Battery System
The 12 volt electrical system is a standard marine
system. There are two batteries, one for the en-
gine and one for the house/accessory circuits and
electronics located in the aft systems compart-
ment. The batteries themselves can be charged
by the engine or the optional battery charger,
when hooked to shore power.
Circuit Protection
Main breakers located near the battery switch
protect the main accessory circuit and optional
stereo amplier. Other circuit breakers or fuses in
the panel or near the batteries protect the circuits
for the battery charger DC circuits, electronics/
stereo memory, and automatic switch for the bilge
pump. Fuses located on each engine protect the
ignition, charging systems and gauges. Other
fuses or circuit breakers provided by the engine
manufacturer protect auxiliary charging circuits
and other engine related electronic controls.
