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.

To replenish the battery:
1. Make sure the electrolyte level is between
the maximum 1 and minimum 2 level
marks.
2. Refill the battery with distilled water if
necessary.
CAUTION:@Normal tap water contains minerals that
are harmful to a battery. Use only dis-
tilled water for replenishing the battery.
@
To charge the battery:
1. Remove the caps from the battery cells.
If the level is low, add distilled water.
2. Connect the battery to a charger. Set the
charging rate at 1.9 A, and then charge
the battery for 10 hours.
WARNING@●The battery gives off explosive gases.
When charging the battery, keep it well
away from sparks and open flames.
●When using a battery charger, connect
the battery to the charger before you
turn the charger on. This will prevent
sparking at the terminals, which could
ignite battery gases.
@
To connect the battery terminals:
1. Make sure the connections are correct
when you insert the battery into the
watercraft.
2. Make sure that the breather hose is
properly connected and that it is not
damaged or obstructed.
3. Make sure the battery is securely held in
place.

CAUTION:@Always avoid operating your watercraft in
areas where weed growth is thick. If trav-
eling in weeded areas is unavoidable,
operate the engine alternately at partial
throttle and full throttle. Weeds tend to
accumulate more at a steady speed and
at trolling speed. If weeds clog the intake
or impeller area and cause cavitation, fol-
low the cleaning procedure above.

Jumping the battery
If the watercraft battery has run down, the
engine can be started using a 12-volt bat-
tery and jumper cables.
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

Submerged watercraft
If the watercraft is submerged or flooded
with water, follow the procedure below and
consult a Yamaha dealer as soon as possi-
ble. Failure to do so may result in serious
engine damage!
1. Beach the watercraft and remove the
hood. Turn the watercraft over far
enough to drain the water from the
engine compartment. Make sure all
water is thoroughly drained.
CAUTION:@Turning the watercraft on its side with the
hood removed could cause damage to
the steering pole. Use two people to pro-
vide enough support to make sure that
the steering pole is not damaged.
@
2. Turn the watercraft upright again.
3. Turn the fuel cock knob to “OFF.”
4. Remove the spark plugs and dry them
with a cloth.
5. Without reinstalling the spark plugs,
crank the engine until all water in the cyl-
inders has been drained.
6. Install the spark plugs.
7. Turn the fuel cock knob to “ON.”
8. Launch the watercraft into the water, and
then run the engine for at least
10 minutes. If engine will not start,
repeat steps above.
9. Turn the engine off. Turn the fuel cock
knob to “OFF.”
10. Remove the silencer cap and spray a
rust inhibitor into the carburetor while
cranking the engine.
11. Have the watercraft inspected by a
Yamaha Dealer as soon as possible.
