Do not run the engine for more than 15
seconds on land without supplying water,
otherwise the engine could overheat.
Spray metallic parts of the hull and engine
with a rust inhibitor.
To rustproof the internal engine components:
(1) Remove the hood. (See page 26 for hoodremoval and installation procedures.)
(2) While loosening the clamp, remove the breather hose.
(3) Make sure that the area around the wa- tercraft is clear, and then start the engine
in a well-ventilated area.
(4) Run the engine at a fast idle.
(5) Quickly spray as much rust inhibitor as possible into the air intake duct through
the breather hose joint. Keep spraying
until the engine stalls (or a maximum of
15 seconds). WARNING! Do not pour or
spray gasoline, or any substance oth-
er than a rust inhibitor, into the air in-
take duct. Do not spray flammable
Recommended water-resistant grease:

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
pages.
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.

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.
EJU3433AAdjusting the steering friction
The amount of friction in the steering can be
adjusted to suit operator preference. To adjust the steering friction:
(1) Lift the steering pole and support it with
the lock pin.
(2) Remove the plastic fasteners, and then remove 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 untilthe 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 the plastic fasteners in their original posi-
tions.
(8) While holding the steering pole, move the lock pin to the stowed position, and
then lower the steering pole.
EJU3128CAdjusting 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) Pull back the outer sleeve of the steering
cable joint, and then disconnect the joint
from the steering cable pivot bolt.
(2) Remove the steering cable pivot bolt.
(3) Select the nozzle angle, install the steer- ing cable pivot bolt in the desired posi-
tion (P1 or P2) on the steering column,
and then tighten the bolt to the specified
torque.
