tightened securely before launching the
watercraft.
EJU32781Engine break-in
The engine break-in period is essential to al-
low the various components of the engine to
wear and polish themselves to the correct op-
erating clearances. This ensures proper per-
formance and promotes longer component
life.
CAUTION:
ECJ00440
Be sure to check the engine oil level be-
fore operating the watercraft for the first

Post-operation care
To keep your watercraft in top shape, always
take it out of the water after using it and per-
form the following procedures. Leaving the
watercraft in the water for extended periods
will accelerate the rate of normal deterioration
of the jet unit components and hull finish. Ma-
rine organisms and corrosion are some of the
conditions that can adversely affect the life of
many watercraft components.
(1) Remove the watercraft from the water.
(2) Wash down the hull, handlebars, and jet
unit with fresh water.
(3) Remove the seat and check the engine
compartment for water. To drain excess
water, remove the stern drain plugs, and
then raise the bow of the watercraft
enough to allow the water in the bilge to
drain out.
NOTE:
This watercraft is equipped with an automatic
bilge draining system that removes water
from the engine compartment while you are
underway. However, some residual water will
remain.
(4) Place the watercraft in a horizontal posi-
tion.
(5) Flush the cooling system to prevent it
from clogging with salt, sand, or dirt. (See
page 66 for flushing procedures.)(6) Drain residual water from the exhaust
system by alternately squeezing and re-
leasing the throttle lever for 10 to 15 sec-
onds while the engine is running.
CAUTION:
ECJ00560
Do not run the engine for more than 15
seconds, otherwise the engine could over-
heat.
(7) If the watercraft will be stored for a week
or more, lubricate internal engine compo-
nents to help prevent corrosion. (See
page 67 for lubrication procedures.)
(8) Rinse the engine and engine compart-
ment with a small amount of water.
CAUTION:
ECJ00570
Do not use high-pressure water when rins-
ing the engine or engine compartment as
severe engine damage could result.
(9) Wipe the engine and engine compart-
ment dry with a clean cloth (repeat step 3,
if necessary).
(10) Wipe the hull, handlebars, and jet unit dry
with a clean cloth.
(11) Spray a rust inhibitor on metallic parts to
minimize corrosion.
(12) Allow the engine compartment to air dry
completely before installing the seat.

Maintenance and care
68

Do not smoke when refueling, and keep
away from sparks, flames, and other
sources of ignition.

Stop the engine before refueling.

Refuel in a well-ventilated area with the
watercraft in a horizontal position.

Do not stand or sit on the watercraft
while refueling in case of fire.

Take care not to spill gasoline. If gaso-
line spills, wipe it up immediately with
dry rags. Always properly dispose of
gasoline-soaked rags.

Avoid overfilling the fuel tank. Stop fill-
ing when the fuel level reaches approxi-
mately 50 mm (2 in) from the top of the
fuel tank. Fuel expands as it warms up
and could overflow if the fuel tank has
been overfilled. If temporarily leaving
the watercraft with a full fuel tank, do not
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.
Top off the fuel tank with fresh gasoline and
add fuel stabilizer and conditioner to the fuel
tank according to the manufacturer’s instruc-
tions.
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
