EJU34452Checking the battery
Check the level of the battery electrolyte and
make sure that the negative (–) and positive
(+) battery leads are tightened securely.
WARNING
EWJ00791
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 a physician im-
mediately.
Eyes: Flush with water for 15 minutes and
get prompt medical attention.
Batteries produce explosive gases. Keep
sparks, flames, cigarettes, etc., well away.
If using or charging the battery in an en-
closed space, make sure that it is well ven-tilated. Always shield your eyes when
working near batteries.
Keep out of the reach of children.
To remove the battery:
Disconnect the negative (–) battery lead first,
then the positive (+) battery lead and breather
hose, and then remove the battery from the
watercraft.
To replenish the battery:
(1) Make sure that the electrolyte level is be-
tween the maximum and minimum level
marks.
(2) If the electrolyte level is low, add distilled
water to raise it to the specified level.
NOTICE: Use only distilled water for
replenishing the battery, otherwise
battery life could be shortened.
[ECJ00241]
To recharge the battery:
NOTICE
ECJ00250
Do not attempt to charge a battery hastily.
Battery life could be shortened.
It is recommended to have a Yamaha dealer
charge the battery. If you charge the battery
yourself, be sure to read and follow the in-
structions provided with the battery tester and
charger you use. Grease quantity:
Initial 10 hours or 1 month:
33.0–35.0 cm³ (1.12–1.18 US oz,

To install the battery:
(1) Place the battery in the battery compart-
ment. Connect the red lead to the positive
(+) battery terminal, and then connect the
black lead to the negative (–) battery ter-
minal. NOTICE: Reversal of the battery
leads will damage the electrical parts.

Emergency procedures EJU34631Cleaning the jet intake and impeller
WARNING
EWJ00780
Before attempting to remove weeds or de-
bris from the jet intake or impeller area,
shut the engine off and remove the clip
from the engine shut-off switch. Severe in-
jury or death could result from coming in
contact with the rotating parts of the jet
pump.
If weeds or debris gets caught in the jet intake
or impeller, cavitation can occur, causing jet
thrust to decrease even though engine speed
rises. If this condition is allowed to continue,
the engine will overheat and may seize.
NOTICE: If weeds or debris gets caught in
the jet intake, do not operate the watercraft
above trolling speed until they have been
removed.
[ECJ00651]
If there is any sign that the jet intake or impel-
ler is clogged with weeds or debris, return to
shore and check the intake and impeller. Al-ways stop the engine before beaching the wa-
tercraft.
(1) Place a suitable clean cloth or carpeting
underneath the watercraft to protect it
from abrasions and scratches. Turn the
watercraft on its side as shown. NOTICE:
Always turn the watercraft over onto
its port (left) side. When turning the
watercraft on its side, support the bow
so that the handlebars are not bent or
damaged.
[ECJ00661]

(2) Remove any weeds or debris from
around the jet intake, drive shaft, impel-
ler, jet pump housing, and jet thrust noz-
zle.
If debris is difficult to remove, consult a
Yamaha dealer.
EJU34641Jumping the battery
If the watercraft battery has run down, the en-
gine can be started using a 12-volt booster
battery and jumper cables.
EJU34662Connecting the jumper cables
WARNING
EWJ01250
To avoid battery explosion and serious
damage to the electrical system:

Do not reverse the polarity of the jumper
cables when connecting to the batteries.

Do not connect the negative (–) jumper
cable to the negative (–) terminal of the
watercraft battery.

Do not touch the positive (+) jumper ca-
ble to the negative (–) jumper cable.
(1) Connect the positive (+) jumper cable to
the positive (+) battery terminals of both
batteries.
(2) Connect one end of the negative (–)
jumper cable to the negative (–) battery
terminal of the booster battery.(3) Connect the other end of the negative (–)
jumper cable to an engine hanger.
(4) Start the engine, and then disconnect the
jumper cables by reversing the steps
above. NOTICE: Never push the start
switch while the engine is running. Do
not operate the start switch for more
than 5 seconds, otherwise the battery
will be discharged and the engine will
not start. Also, the starter motor could
be damaged. If the engine does not
start in 5 seconds, release the start
switch, wait 15 seconds, and then try
again.
