EJU32863Stopping the engine
Release the throttle lever, and then push the
engine stop switch (red button) to stop the
engine. WARNING! You need throttle to
steer. Shutting the engine off can cause
you to hit an obstacle you are attempting
to avoid. A collision could result in severe
injury or death.

EJU32873
Leaving the watercraft
If leaving the watercraft, remove the clip from
the engine shut-off switch to prevent acci-
dental starting or unauthorized operation by
children or others.
EJU41172Operating the watercraft
When the engine is running, the watercraft
will move forward at trolling speed even if thethrottle lever is in the fully closed (idle) posi-
tion.
EJU33244Turning the watercraft
WARNING
EWJ00762
Do not release the throttle lever when
trying to steer away from objects—you
need throttle to steer. A collision could
result in severe injury or death.
When operating at higher speeds, make
gradual turns or slow down before turn-
ing. Sharp high-speed turns may cause
the watercraft to slide sideways or spin,
throwing the operator overboard, which
could cause an injury.
Steering control depends on the combination
of handlebar position and the amount of
throttle.
Water sucked in through the intake grate is
pressurized by the impeller in the jet pump.
As the pressurized water is expelled from the
pump through the jet thrust nozzle, it creates
thrust to move and steer the watercraft. The
higher the engine speed, the more thrust pro-
duced.
The amount of jet thrust, in addition to the po-
sition of the handlebars, determines how
sharply you turn.

general, the higher the speed or the sharper
the turn, the more you lean.
EJU33273Stopping the watercraft
The watercraft is not equipped with a sepa-
rate braking system. It is stopped by water
resistance when the throttle lever is released.
From full speed, the watercraft comes to a
complete stop in approximately 90 m (300 ft)
after the throttle lever is released or the en-
gine is stopped, although this distance will
vary depending on many factors, including
gross weight, water surface conditions, and
wind direction. The watercraft slows down as
soon as the throttle lever is released, but will
coast for a distance before fully stopping. If
you are not sure you can stop in time beforehitting an obstacle, apply throttle and turn in
another direction.
WARNING
EWJ00723
Allow adequate stopping distance.
Take early action to avoid collisions. Re-
member, watercraft and other boats do
not have brakes.
Operate defensively at safe speeds and
keep a safe distance away from people,
objects, and other watercraft to give you
time to stop.
Do not shut the engine off when slowing
down in case you need engine power to
steer away from a boat or other obstacle
that comes into your path.
EJU33075Starting off
WARNING
EWJ00712
To avoid collisions:
Scan constantly for people, objects, and
other watercraft. Be alert for conditions
that limit your visibility or block your vi-
sion of others.
Operate defensively at safe speeds and
keep a safe distance away from people,
objects, and other watercraft.
Do not follow directly behind watercraft
or other boats. Do not go near others to
spray or splash them with water. Avoid

see “Towing the watercraft” on page 68
or “Submerged watercraft” on page 69.)
NOTICE: Do not run the engine at full
throttle for at least 1 minute after the
engine has been restarted. Bilge wa-
ter in the engine compartment can
splash into the engine, which can re-
sult in severe damage.
[ECJ00554]
EJU33303
Beaching the watercraft
To beach the watercraft:
(1) Make sure that there are no boats, swim- mers, or obstacles near the beach.
(2) Release the throttle lever to reduce speed about 90 m (300 ft) before you
reach the intended beaching area.
(3) Slowly approach the beach and stop the engine just before reaching land.
WARNING! You need throttle to steer. Shutting the engine off can cause you
to hit an obstacle you are attempting
to avoid. A collision could result in se-
vere injury or death.
[EWJ00602] NOTICE:
Never run the engine in water that is
less than 60 cm (2 ft) deep from the
bottom of the watercraft, otherwise
pebbles or sand could be sucked into
the jet intake, causing impeller dam-
age and engine overheating.
[ECJ00473]
(4) Get off the watercraft and pull it up on the beach.
EJU37194Operating in weeded areas
Always avoid using your watercraft in areas
where weed growth is thick. If operating in
weeded areas is unavoidable, alternately
squeeze the throttle lever and relax your grip
on the throttle lever to vary the engine speed.
Weeds tend to become clogged more when
operating at a steady speed and at trolling
speed. If weeds may have clogged the intake area, clean the jet intake. (See page 66 for in-
formation on the jet intake.)
EJU41061After removing the watercraft from
the water
NOTICE
ECJ01361
Do not run the engine for more than 15
seconds on land without supplying water,
otherwise the engine could overheat.
After operating and removing the watercraft
from the water, promptly discharge the re-
maining water from th
e cooling water pas-
sages.
To discharge water from the cooling water
passages:
(1) Make sure that the area around the wa- tercraft is clear, and then start the en-
gine.
(2) Discharge the remaining water out of the cooling water passages by alternately
squeezing and releasing the throttle lever
quickly for 10 to 15 seconds.
(3) Stop the engine.

Steering cable ball joint (handlebar end)
and steering cable inner wire (handlebar
end)
To access the steering cable ball joint (han-
dlebar end) and steering cable inner wire
(handlebar end), remove the steering pole
cover. (See step 1 in “Adjusting the jet
thrust nozzle angle” on page 57 for infor-
mation on removing the steering pole cov-
er.)

EJU40944Rustproofing
NOTICE
ECJ01361
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 24 for hood
removal and installation procedures.)
(2) Loosen the silencer cap and remove it.
(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 through the hole in the silencer
cover. Keep spraying until the engine
stalls (or a maximum of 15 seconds).
WARNING! Do not pour or spray gaso-
line, or any substance other than a
rust inhibitor through the hole in the
silencer cover. Do not spray flamma-
ble rust inhibitor products on engine
surfaces while the engine is hot. Oth-
erwise, a fire or explosion could oc-
cur.
[EWJ00302]
(6) Securely install the silencer cap by tight-
ening it until it stops. NOTICE: Be sure
to install the silencer cap securely af-
ter fogging the engine, otherwise wa-
ter could enter the engine and cause
damage.
[ECJ00153]
(7) Securely install the hood in its original
position.

Maintenance

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.
