OPERATION
Pre-Operation Inspection
Battery
Causing sparks while servicing the battery or servicing the battery
when gas fumes are present can result in an explosion, causing
serious injury or death.
Never create a spark while servicing the battery. If you smell fuel in
the craft, do not service the battery. Take the watercraft to your
dealer immediately for inspection.
Confirm that the battery terminal connections
are tight, and make sure the battery is
securely fastened in its mounting position.
Inspect the battery for leaks, and check the
vent hose for kinks or blockage.
Check the battery fluid level and add only
distilled water if the level is low. Tap water
contains minerals that are harmful to a battery.
Maintain the fluid level between the upper and lower marks (1) on the
battery.
Keep the battery in good condition and fully charged at all times, as a
weak battery can leave you stranded. Never operate the watercraft with
a battery that's too weak to start the engine on its own or shows signs
of loss of power.
