Maintenance
Periodic checks and lubrication will keep your
watercraft in the safest and most efficient con-
dition possible. Therefore, make sure to carry
out the periodic maintenance. Safety is an ob-
ligation of the watercraft owner. Proper main-
tenance must be carried out to keep the
exhaust emission and sound levels within the
regulated limits. The most important points of
watercraft inspection and lubrication are ex-
plained 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.

(4) Loosen the locknut.
(5) Tighten or loosen the adjusting nut until
the desired amount of friction is obtained.
(6) While holding the adjusting nut with a
wrench, tighten the locknut to the speci-
fied torque.
(7) Securely install the handlebar cover and
four screws in their original positions.(8) While holding the steering pole, move the
lock pin to the stowed position, and then
lower the steering pole.
EJU31288Adjusting the jet thrust nozzle angle

justed to two settings to suit operator prefer-
ence.
To adjust the jet thrust nozzle angle:
(1) Remove the two bolts, and then remove
the steering pole cover.
(2) Pull back the outer sleeve of the steering

EJU34463Adjusting the carburetor
NOTICE
ECJ00172
If the carburetor settings are disturbed by
someone who does not have the neces-
sary technical knowledge, poor engine
performance and damage may result.
The carburetor is a vital part of the engine and
requires very sophisticated adjustments.
Most adjustments should be left to a Yamaha
dealer who has the professional knowledge
and experience to make them.
However, the operator may adjust the engine
idling speed as part of the usual maintenance
routine.
EJU34471Adjusting the engine idling speed
(1) Place the watercraft in the water.
(2) Start the engine and warm it up for 1 to 2
minutes.
(3) While using a diagnostic tachometer, turn
the throttle stop screw to adjust the en-
gine idling speed to specification. Turn
the throttle stop screw clockwise to in-
crease the engine idling speed or coun-
terclockwise to decrease the engine
idling speed.
1Throttle stop screw
Engine idling speed:
1300 ±50 r/min
