DANGER
Battery Boxes
• 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.
!
CAUTION
The batteries should always
be enclosed in the covered
battery boxes provided with
your boat. The box will
contain any spilled acid, as
well as protect the battery
terminals from damage or
inadvertant shorting from
coming in contact with metal objects. Each battery
box should always be secured in place by using the
straps and clamps provided, the straps will ensure that
while underway the battery will not move around,
causing damage to components stored in the same
area.
The two (2) standard battery boxes can be accessed
through aft cockpit hatch
Before use, check each battery for loose connections
or wiring. Normal maintenance should include:
• Coat the terminals with dielectric grease
• Keep the batteries dry
