ter flows out continually from the jet
thrust nozzle.
(8) Run the engine at idling speed for about 3 minutes watching the engine condition.
If the engine stops while flushing, turn
the water supply off immediately and
perform the procedure again from step 7.
NOTICE: Do not supply water to the
cooling water passages when the en-
gine is not running. The water could
flow back through the muffler into the
engine, causing severe engine dam-
age.
[ECJ00123]
(9) Turn the water supply off.
(10) Discharge the remaining water out of the cooling water passages by alternately
squeezing and releasing the throttle lever
quickly for 10 to 15 seconds.
(11) Stop the engine.
(12) Remove the garden hose adapter, and then securely install the flushing hose
connector cap by tightening it until it
stops.
(13) Securely close the stern storage com- partment.
(14) Securely install the removable watertight storage compartment and seats in their
original positions.
EJU33736Cleaning the watercraft
(1) Remove the seats. (See page 49 for seatremoval and installation procedures.) (2) Rinse the engine and engine compart-
ment with a small amount of water.
NOTICE: Do not use high-pressure
water when rinsing the engine or en-
gine compartment as severe engine
damage could result.
[ECJ00572]
(3) Drain the water from the engine com- partment. (See page 61 for information
on draining the bilge water.)
(4) Wipe the engine and engine compart- ment with a dry cloth.
(5) Wash down the hull, deck, and jet pump with fresh water.
(6) Wipe the hull, deck, and jet pump with a dry cloth.
(7) Wipe all vinyl and rubber components, such as the seats and engine compart-
ment seals, with a vinyl protectant.
(8) To minimize corrosion, spray metallic parts of the hull, deck, and engine with a
rust inhibitor.
(9) Allow the engine compartment to air dry completely before installing the seats.
(10) Securely install the seats in their original positions.
EJU33687Battery care
If the watercraft will not be used for more than
a month, remove the battery from the water-
craft, check it, and then store it in a cool, dry
place.
WARNING
EWJ00792
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
ventilated. Always shield your eyes when
working near batteries.
Keep out of the reach of children.
To remove the battery:
(1) Disconnect the negative (–) battery lead.
(2) Disconnect the positive (+) battery lead.
(3) Disconnect the breather hose.
(4) Unhook the battery bands, and then re-move the battery from the watercraft.
Checking the battery
Make sure that the battery case is not dam-
aged.
Make sure that the battery terminals are
not corroded or damaged.
Make sure that the breather hose is not
clogged or damaged. Checking the electrolyte level
Make sure that the electrolyte level is be-
tween the maximum and minimum level
marks.
If the electrolyte level is low, add distilled wa-
ter to raise it to the specified level.
NOTICE:
Use only distilled water for replenishing
the battery, otherwise battery life could be
shortened.
[ECJ00242]
If distilled water was added, check the bat-
tery voltage.
It is recommended to have a Yamaha dealer
check the battery voltage and charge the bat-
tery. If you charge the battery yourself, be
sure to read and follow the instructions pro-
vided with the battery tester and charger you
use. NOTICE: Do not attempt to charge a
battery hastily. Battery life could be short-
ened.

Checking the battery bands
Make sure that the battery bands are not
damaged.
To store the battery:
(1) Clean the battery case using fresh water.
(2) If the battery terminals are dirty or cor-roded, clean them using a wire brush.
(3) Apply Yamaha Marine Grease or Yamaha Grease A to the battery termi-nals.
(4) Store the battery in a cool, dry place. NOTICE: Storing the battery in an un-
charged condition can cause perma-
nent battery damage. Check the
battery periodically.
[ECJ00103]
To install the battery:
(1) Place the battery in the battery compart- ment and hook the battery bands onto
the holders.
(2) Connect the positive (+) battery lead (red) to the positive (+) battery terminal.
NOTICE: Reversal of the battery leads
will damage the electrical parts.
[ECJ00262]
(3) Connect the negative (–) battery lead (black) to the negative (–) battery termi-
nal.
(4) Connect the breather hose to the bat- tery. WARNING! Fire or explosion
could result if the breather hose is
damaged, obstructed, or not connect-
ed properly.

If debris is difficult to remove, consult a
Yamaha dealer.
EJU34642Jumping the battery
If the watercraft battery has run down, the en-
gine can be started using a 12-volt booster
battery and jumper cables.
EJU34664Connecting the jumper cables
WARNING
EWJ01251
To avoid battery explosion and serious
damage to the electrical system:
Do not reverse the polarity of the jumper
cables when connecting to the batter-
ies.
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. (See page 28 for information on
starting the engine.)
EJU36995Replacing the fuses
If a fuse is blown, replace it with the proper
fuse.
To replace a fuse:

(2) Remove the electrical box cover.
(3) Loosen the cap on the electrical box andremove it.
(4) Replace the blown fuse with the spare fuse of the correct amperage by using
the fuse puller on the reverse side of the
cap. WARNING! Do not use fuses of a
different amperage than recommend-
ed. Substitution with a fuse that has
an improper rating can cause exten- sive electrical system damage and
possible fire.
