tween the minimum and maximum level
marks.
(4) If the engine oil level is below the mini-
mum level mark, perform steps 5–7 to
add enough oil so that the oil level is be-
tween the minimum and maximum level
marks on the dipstick. If the engine oil lev-
el is significantly above the maximum lev-
el mark, have a Yamaha dealer service
the watercraft.(5) Remove the engine oil filler cap.
(6) Pour engine oil into the filler hole. Wait
approximately 5 minutes until the engine
oil settles.
TIP:
The difference between the minimum and
maximum level marks on the dipstick is equal
to approximately 1 liter of engine oil.
(7) Repeat steps 3–6 until the engine oil is at
the proper level.
(8) Install the engine oil filler cap, and then
install the seats.

Storage
WARNING
EWJ00330
Always place the watercraft upright in a
horizontal position when storing it, other-
wise fuel could leak out into the engine or
engine compartment, which could create a
fire hazard.
Storage for long periods of time, such as win-
ter storage, requires preventive maintenance
to ensure against deterioration. It is advisable
to have the watercraft serviced by a Yamaha
dealer prior to storage. However, the following
procedures can be performed by the owner.
EJU37202Flushing the cooling system
Flushing the cooling system is essential to
prevent it from clogging with salt, sand, or dirt.
(1) Place the watercraft in a horizontal posi-
tion.
(2) Remove the rear seat and seat storage
compartment. (See page 25 for seat re-
moval and installation procedures.)
(3) Remove the flushing hose connector
cap, and then insert the garden hose
adapter into the flushing hose connector
and turn it until it is securely connected.(4) Connect the garden hose adapter to a
water tap using a garden hose.
TIP:
A garden hose is not included.
(5) Start the engine, and then immediately
turn the water supply on until water flows
out continually from the jet thrust nozzle.
NOTICE: Do not run the engine for
more than 15 seconds without supply-
ing water or over 4000 r/min on land,
otherwise the engine could overheat.
[ECJ01050]
TIP:
If you will be storing the watercraft for a pro-
longed period, such as winter storage, top off
the fuel tank with fresh gasoline and add fuel
stabilizer and conditioner to the fuel tank ac-
cording to the manufacturer’s instruction be-
fore starting the engine.
(6) 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 repeat
the above steps. NOTICE: Do not sup-
ply water to the cooling water passag-
es when the engine is not running. The
water could flow back through the
muffler into the engine, causing se-
vere engine damage.
[ECJ00122]
(7) Turn the water supply off, and then force
the remaining water out of the cooling

Maintenance and adjustments
Periodic inspection, adjustment, and lubrica-
tion will keep your watercraft in the safest and
most efficient condition possible. Safety is an
obligation of the watercraft owner. Proper
maintenance must be carried out to keep the
exhaust emission and sound levels within the
regulated limits. The most important points of
watercraft inspection, adjustment, and lubri-
cation are explained on the following pages.
See a Yamaha dealer for genuine Yamaha re-
placement parts and optional accessories de-
signed for your watercraft.
Remember, failures that are the result of the
installation of parts or accessories which are
not qualitatively equivalent to genuine
Yamaha parts are not covered by the limited
warranty.
Maintenance, replacement, or repair of the
emission control devices and system may
be performed by any marine SI engine re-
pair establishment or individual. Warranty
repair, however, must be performed at an
authorized Yamaha marine dealership.
WARNING
EWJ00311
Be sure to turn off the engine when you
perform maintenance unless otherwise
specified. If you are not familiar with ma-
chine servicing, this work should be done
by a Yamaha dealer or other qualified me-
chanic.
EJU33811Owner’s/operator’s manual and tool
kit
It is advisable to always carry the owner’s/op-
erator’s manual and tool kit with you whenev-
er you use the watercraft. For your
convenience, a storage compartment is pro-vided on the watercraft for the manual and
tool kit.
To protect these materials from water dam-
age, it would be a good idea to put them in a
waterproof bag.
The service information included in this man-
ual is intended to provide you, the owner, with
the necessary information for completing your
own preventive maintenance and minor re-
pairs. The tools provided in the tool kit are suf-
ficient for this purpose, except that a torque
wrench may also be necessary to tighten nuts
and bolts.

EJU37041Cleaning and adjusting the spark
plugs
WARNING
EWJ00350
Be careful not to damage the insulator
when removing or installing a spark plug.
A damaged insulator could allow sparks to
escape, which could result in a fire or ex-
plosion.
The spark plug is an important engine compo-
nent and is easy to inspect. The condition of
the spark plug can indicate something about
the condition of the engine. For example, if
one spark plug has a distinctly different color,
the engine could require servicing. Do not at-
tempt to diagnose any problems yourself.
Have a Yamaha dealer service the watercraft.Remove and inspect the spark plugs periodi-
cally; heat and deposits will cause the spark
plugs to slowly break down and erode. If elec-
trode erosion becomes excessive, or if carbon
and other deposits are excessive, replace the
spark plug with the specified plug.
To remove a spark plug:
(1) Remove the seats. (See page 25 for seat
removal and installation procedures.)
(2) Remove the engine cover screws, and
then remove the engine cover.
(3) Remove the spark plug cap bolts, and
then remove the spark plug cap.
NOTICE: Do not use any tools to re-
move or install the spark plug cap,
otherwise the ignition coil coupler
could be damaged. The spark plug
cap may be difficult to remove be-
cause the rubber seal on the end of
the cap fits tightly. To remove the
spark plug cap, simply twist it back
and forth while pulling it up; to install
it, twist it back and forth while pushing
it down.
