(4) Push the start switch (green button), and
then release it as soon as the engine
starts to run.
NOTE:
The engine will not start if the throttle lever is
squeezed.
CAUTION:
ECJ00480

Never push the start switch while the en-
gine 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.
EJU32860Stopping the engine
To stop the engine, release the throttle lever,
and then push the engine stop switch (red
button).
WARNING
EWJ00600
You need throttle to steer. Shutting the en-
gine off can cause you to hit an obstacle
you are attempting to avoid. A collision
could result in severe injury or death.
EJU32881Leaving the watercraft
If leaving the watercraft, select the lock mode
of the Yamaha Security System and remove
the engine shut-off cord to reduce the chance
of accidental starting or unauthorized use by
children or others. (See page 33 for Yamaha
Security System lock and unlock mode selec-
tion procedures.)

leave it in direct sunlight. Leave it in a
well-ventilated area with the watercraft
in a horizontal position.

Tighten the fuel tank filler cap securely
after refueling.

If you should swallow some gasoline, in-
hale a lot of gasoline vapor, or get gaso-
line in your eyes, get immediate medical
attention.

If any gasoline spills on your skin or
clothing, immediately wash the affected
area with soap and water and change
your clothes.
Add approximately 550 ml (18.6 US oz, 19.4
Imp oz) of Yamaha Fuel Stabilizer and Condi-
tioner to the fuel tank, and then top it off with
fresh gasoline.
CAUTION:
ECJ00140
Use only Yamaha Fuel Stabilizer and Con-
ditioner, otherwise the catalytic converter
could be seriously damaged.
EJU33680Battery
If the watercraft will not be used for more than
a month, remove the battery from the water-
craft and store it in a cool, dry place.
(1) Disconnect the negative (–) battery lead
first, then the positive (+) battery lead and
breather hose, and then remove the bat-
tery from the watercraft.
(2) Clean the battery casing using fresh wa-
ter.
(3) If the battery terminals are dirty or corrod-
ed, clean them with a wire brush.
(4) Fully charge the battery.
(5) Apply Yamaha Marine Grease or
Yamaha Grease A to the battery termi-
nals, and then store the battery in a cool,
dry place.(6) Check the battery at least once every 2
months and fully charge it if necessary.
CAUTION:
ECJ00100
Always keep the battery charged. Storing
a discharged battery can cause permanent
battery damage.
To check the condition of the battery, check
the specific gravity of the electrolyte or mea-
sure the voltage at both battery terminals.
Charge the battery if the voltage is less than
12 volts.
It is recommended to have a Yamaha dealer
check the specific gravity and charge the bat-
tery. If you maintain the battery yourself, be
sure to read and follow the instructions provid-
ed with the battery tester and charger you
use.
EJU33730Cleaning the watercraft
Clean the watercraft before storing it for a long
period.
(1) Wash down the hull, handlebars, and jet
unit with fresh water.
(2) Rinse the engine and bilge area with
fresh water. Drain all of the water and
wipe up any remaining moisture with
clean, dry rags.
CAUTION:
ECJ00110
Do not use high-pressure water when rins-
ing the engine and bilge area as severe en-
gine damage could result.
(3) Spray the engine’s exterior with a rust in-
hibitor and lubricant.
(4) Wax the hull with a non-abrasive wax.Specific gravity (for reference):
1.28 at 20 °C (68 °F)

WARNING
EWJ00790
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.
CAUTION:
ECJ00230

Be careful not to place the battery on its

Be sure to remove the battery from the
battery compartment when adding elec-
trolyte or charging the battery.
To replenish the battery:
(1) Make sure that the electrolyte level is be-
tween the maximum and minimum level
marks.
(2) Refill the battery with distilled water if
necessary.
CAUTION:
ECJ00240
Normal tap water contains minerals that
are harmful to a battery. Use only distilled
water for replenishing the battery.
To recharge the battery:
CAUTION:
ECJ00250
Do not attempt to charge a battery hastily.

It is recommended to have a Yamaha dealer
charge the battery. If you charge the battery
yourself, carefully read the battery charger in-
structions before charging and follow the
points below.
(1) Remove all of the battery caps.
(2) If the electrolyte level is low, add distilled
water to raise it to the specified level.
(3) Set the charging rate to 1.9 ampere and
charge the battery slowly until the explo-
sive gases are discharged vigorously
from the battery cells.

ed, or not connected properly.
CAUTION:
ECJ00260
After installation, make sure that the bat-
tery leads are properly connected to the
battery terminals.
EJU34490Fuel injection system
The fuel injection system was set at the
Yamaha factory. If the fuel injection system
needs to be adjusted, have a Yamaha dealer

system. If the settings are disturbed by
someone who does not have the neces-sary technical knowledge, poor engine
performance and damage may result.
EJU34500Checking the trolling speed
(1) Place the watercraft in the water.
