(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 removethe 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
in the desired position (P1 or P2) on the
steering column, and then tighten the
bolt to the specified torque.TIP:
The outermost hole in the steering column
cannot be used.

EJU34379Checking the spark plugs
WARNING
EWJ00351
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.
Remove and check the condition of the spark
plugs.
The condition of a spark plug can indicate
something about the condition of the engine.
For example, if the center electrode portion is
very white, this could indicate an intake air
leak or carburetion problem in that cylinder.
Do not attempt to diagnose any problems
yourself. Have a Yamaha dealer service the
watercraft.
To remove a spark plug:
(1) Remove the hood. (See page 24 for hoodremoval and installation procedures.)
(2) Remove the spark plug cap.
(3) Remove the spark plug, and then check the condition of the spark plug and the
spark plug gap. If the electrode portion is
significantly discolored, if electrode ero-
sion becomes excessive, if carbon and
other deposits are excessive, or if the
spark plug gap is not within the specified
range, replace the spark plug.
TIP:
When the engine is operating normally, the
color of the spark plug electrode portion will
be a medium-to-light tan.
To install a spark plug:
(1) Wipe off any dirt from the threads, insu-lator, and gasket surface of the spark
plug.
(2) Install the spark plug, and then tighten it to the specified torque.
TIP:
If a torque wrench is not available when you
are installing a spark plug, a good estimate of
the correct torque is 1/4 turn to 1/2 turn past
finger tight using the spark plug wrench in-
cluded in the tool kit. Have the spark plug ad-
justed to the correct torque with a torque
wrench as soon as possible.
