Maintenance
Periodic checks and lubrication will keep
your watercraft in the safest and most effi-
cient condition possible. Therefore, make
sure to carry out the periodic maintenance.
Safety is an obligation of the watercraft own-
er. Proper maintenance must be carried out
to keep the exhaust emission and sound lev-
els within the regulated limits. The most im-
portant points of watercraft inspection and
lubrication are explained on the following pa-
ges.
See a Yamaha dealer for genuine Yamaha re-
placement parts and optional accessories
designed 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
repair establishment or individual. War-
ranty repair, however, must be performed
at an authorized Yamaha marine dealer-
ship.
WARNING
EWJ00312
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.
EJU33803Tool kit
A tool kit is included with this watercraft. Pla-
ce the tool kit in a waterproof bag and alwayscarry it with you whenever you use the water-
craft.
EJU34337Adjusting the steering friction
The amount of friction in the steering can be
adjusted to suit operator preference.

(2) Remove the four screws, and then re-
move the handlebar cover.
(3) Turn the handlebars so that the left han-
dlebar grip is facing down.
(4) Loosen the locknut.
(5) Tighten or loosen the adjusting nut until
the desired amount of friction is ob-
tained.
(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.
EJU31289Adjusting the jet thrust nozzle angle
The angle of the jet thrust nozzle can be ad-
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
cable joint, and then disconnect the joint
from the steering cable pivot bolt.

(3) Remove the steering cable pivot bolt.
(4) Select the nozzle angle, install the steer-
ing cable pivot bolt with the lock washer

steering column, and then tighten the
bolt to the specified torque.TIP:
The outermost hole in the steering column
cannot be used.

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.
EJU34472Adjusting 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
engine 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.
