Battery
Check the battery condition and the elec-
trolyte level. Check that the battery leads are
tightened securely and there is no corrosion
on the battery terminals.
WARNING@The battery must always be fully charged
and in good condition. Loss of battery
power may leave you stranded. Never
operate the watercraft if the battery does
not have sufficient power to start the
engine or if it shows any other signs of
decreased power.
@
Make sure that the breather hose is prop-
erly connected and that it is not damaged or
obstructed.
Make sure that the battery is securely
held in place.

Fuel system
Draining the fuel system prevents buildup
of varnishes and other harmful deposits that
result when gasoline sits for a prolonged
period of time.
WARNING@Gasoline is highly flammable and explo-
sive. A fire or explosion can cause
severe injury or death. Shut the engine
off. Refuel in well-ventilated areas away
from flames or sparks. Do not smoke.
Avoid spilling gasoline. Wipe up spilled
gasoline immediately.
@
To drain the fuel system:
1. Place the fuel cock knob in the “OFF”
position.
2. Drain the fuel tank using a siphon.

Battery
When the watercraft is not to be used for
a month or more, remove the battery and
store it in a cool, dark place. Clean the bat-
tery’s casing and terminals using a mixture
of baking soda and water (one tablespoon of
baking soda to one cup of water). Apply
dielectric grease or petroleum jelly to the
battery terminals and to all exposed battery
leads.
If the battery is to be stored for a longer
period, check the specific gravity of the elec-
trolyte at least once a month and charge the
battery if necessary.
Specific gravity: 1.28 at 20 °C (68 °F)

Inspecting the battery
Check the level of the battery electrolyte
and make sure the leads are secure.
WARNING@Battery electrolyte is poisonous and dan-
gerous, causing severe burns, etc. Elec-
trolyte contains sulfuric acid. Avoid
contact with skin, eyes or clothing.
Antidotes
External: Flush with water.
Internal: Drink large quantities of water
or milk. Follow with milk of magnesia,
beaten egg or vegetable oil. Call physi-
cian immediately.
Eyes: Flush with water for 15 minutes
and get prompt medical attention.
Batteries produce explosive gases. Keep
sparks, flame, cigarettes, etc., well away.
If using or charging the battery in an
enclosed space, make sure that it is well
ventilated. Always shield your eyes when
working near batteries.
KEEP OUT OF THE REACH OF CHIL-
DREN.
@
CAUTION:
Be careful not to place the battery on its
side.
Make sure to remove the battery from the
battery compartment when adding the
battery electrolyte or charging the bat-
tery.
When checking the battery, make sure
the breather hose is connected to the
battery and not obstructed.
