(3) Check that the QSTS selector turns
smoothly when the lever is squeezed and
held in place.
(4) Check that the angle of the jet thrust noz-
zle changes when the QSTS selector is
shifted from neutral to bow up or bow
down.
If the mechanism does not work properly,
have a Yamaha dealer service it.
EJU32650Jet intake
Carefully check the jet intake for weeds, de-
bris, or anything else that might restrict the in-
take of water. If the jet intake is clogged,
cavitation could occur, reducing jet thrust, and
possibly damaging the jet pump.
In some cases, the engine may overheat be-
cause of lack of cooling water, and damage to
the engine could result. Cooling water is fed to
the engine by the jet pump. (See page 76 for
jet intake cleaning procedures.)
WARNING
EWJ00470

Keep away from the intake grate while
the engine is on. Items such as long hair,
loose clothing, or PFD straps can be-
come entangled in moving parts, result-
ing in severe injury or drowning.

Stop the engine and remove the clip
from the engine shut-off switch before
removing any debris or weeds, which
may have collected around the jet in-
take.

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.
EJU33520Flushing the cooling system
Flushing the cooling system is essential to
prevent it from clogging with salt, sand, or dirt.
WARNING
EWJ00270
Do not start the engine on land if anyone is
behind the watercraft. Hot water and
steam spurting from the exhaust outlet
into the air can cause serious burns.
CAUTION:
ECJ00130

Do not supply water to the cooling water
passages when the engine is not run-
ning. The water could flow back through
the muffler into the crankcase, causing
severe engine damage.

Do not run the engine for more than 15
seconds on land without supplying wa-
ter, otherwise the engine could over-
heat.

Do not run the engine over 4000 r/min on
land, otherwise the catalytic converter
could be seriously damaged.
(1) Remove the watercraft from the water
and place it in a horizontal position.(2) 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.
(3) Connect the garden hose adapter to a
water tap using a garden hose.
NOTE:
A garden hose is not included and must be
purchased separately.
(4) Start the engine, and then immediately
turn the water supply on until water flows
out continually from the cooling water pi-
lot outlet.
(5) 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.
(6) Turn the water supply off, and then force
the remaining water out of the cooling
water passages by running the engine at
4000 r/min or less for 10 to 15 seconds.
(7) Stop the engine.
(8) Remove the garden hose adapter and in-
stall the flushing hose connector cap.

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
EWJ00310

Be sure to shut the engine off when you
perform maintenance unless otherwise
specified, otherwise an accident or inju-
ry could result from unexpected opera-
tion, moving parts, or electric shock. If
the owner is not familiar with watercraft
servicing, this work should be done by a
Yamaha dealer. Improperly serviced
components could fail or stop operating
correctly, which could result in an acci-
dent.

Modifications to this watercraft not ap-
proved by Yamaha may cause loss of
performance or excessive noise and ex-
haust emissions, or render it unsafe foruse. Consult a Yamaha dealer before at-
tempting any modifications.
EJU33810Owner’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.
NOTE:
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

EJU34360Checking and adjusting the throttle
cable
Check that the throttle cable moves back to
the set position smoothly and that the throttle
lever free play is within specification.
(1) Squeeze and release the throttle lever. If
the throttle lever does not return smooth-
ly, have a Yamaha dealer service it.(2) Adjust the free play by loosening the lock-
nut and turning the adjuster.
EJU34371Cleaning 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 the
center electrode porcelain is very white, this
could indicate an intake air leak or carburetion
problem in that cylinder. Do not attempt to di-
agnose 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 Difference of A and B:
