Electrical System

DANGER
!
Batteries contain sulfuric acid which is
dangerous and can cause serious injury.
AVOID contact with skin, eyes and clothing. If
contact occurs, immediately fl ush the affected
area with large quantities of water and call for
medical assistance
CAUTION
!
• Never use an open fl ame in the battery
storage area.
• Avoid striking sparks near the battery.
• A battery will explode if a fl ame or spark
ignites the free hydrogen given off during
charging.
• The battery should always be disconnected
before doing any work or maintenance on
the electrical system.
• Never reset a breaker without fi rst
determining and correcting the cause of the
trip. Should a circuit repeatedly trip, have
a qualifi ed electrician determine and correct
the cause.
• If equipped with a battery switch, you will
need to stop the engine before moving the
switch to the "OFF" position.

Battery

Your boat has an electrical system powered by two
lead-acid batteries. The batteries are charged by the
engine when the engine is running. Either, or both,
batteries can be selected by the battery switch to
power the following systems:
• Engine ignition
• Engine tilt trim system
• Helm switch panel & helm instrument panel
• Lighting/Navigation system
• Livewell system
• Add-on accessories and electronics
The batteries should always be kept in the battery
trays provided with your boat. The trays are located

in the starboard stern bilge and can be accessed
through the starboard stern deck access hatch (See
fi gure 4.1.1).
The trays will ensure that while underway the
batteries will not move around, thus causing damage
to themselves, components fi tted in the same area
or the boat itself. The batteries can be removed by
loosening the turn knobs at the top ends of the trays
and removing the retaining lid on the battery tray.

Battery Maintenance

The most life shortening experience for the battery
is too be drained to zero charge before recharging.
When a battery discharges, the active material on
both positive and negative plates converts to lead
sulfate, causing the plates to become more alike in an
electrical charge. The electricity conducting battery
acid becomes weaker and the voltage drops. As the
battery remains discharged, the process continues
until recharging the battery becomes impossible. If
the battery does become run down be sure to recharge
it as soon as possible. Over charging the battery can
be just as detrimental to its life as running it down
too far.
