general, the higher the speed or the sharper
the turn, the more you lean.
EJU33272Stopping the watercraft
The watercraft is not equipped with a sepa-
rate braking system. It is stopped by water re-
sistance 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
EWJ00722
●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.
EJU33074Starting off
WARNING
EWJ00711
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

sharp turns or other maneuvers that
make it hard for others to avoid you or
understand where you are going. Avoid
areas with submerged objects or shal-
low water.
●Take early action to avoid collisions. Re-
member, watercraft and other boats do
not have brakes. Do not release the
throttle lever when trying to steer away
from objects—you need throttle to steer.
WARNING
EWJ00632
Avoid forceful jet thrust and limited visibil-
ity while reboarding. Get to a standing or
kneeling position quickly, but do not ex-
pose yourself to the forceful jet thrust.
NOTICE
ECJ01340
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, caus-
ing impeller damage and engine overheat-
ing.
The watercraft is less stable when at a stand-
still or at a slow speed. It takes skill to keep the
watercraft upright when starting.
To stabilize the watercraft when accelerating
to planing speed, maintain a low center of
gravity by operating it in the kneeling position.Even though it is easier to start in shallow wa-
ter, you must learn deep-water boarding first.
You will inevitably fall off, so be sure you know
how to get back on the watercraft once you
are away from shore.
EJU33104Boarding and starting in shallow water
Be sure to learn the deep-water starting meth-
od before operating the watercraft in water
where it is too deep for you to stand. (See
page 47 for the deep-water starting method.)
(1) Launch the watercraft in water free from
weeds and debris and at least 60 cm (2 ft)
deep from the bottom of the watercraft.
NOTICE: Never run the engine in water
that is less than 60 cm (2 ft) deep from
the bottom of the watercraft, other-
wise pebbles or sand could be sucked
into the jet intake, causing impeller
damage and engine overheating.
[ECJ00472]
(2) Attach the engine shut-off cord (lanyard) to your left wrist, and then attach the clip
to the engine shut-off switch.
(3) Grip the handlebars with both hands. Place one knee on the riding tray and bal-
ance there.
(4) Look in all directions, start the engine, and then begin to accelerate.

(5) Pull your other knee up onto the ridingtray as the watercraft speed increases.
(6) Move as far forward as possible without interfering with the movement of the han-
dlebars. Keep your body perpendicular to
the water, with your weight forward and
low.
TIP:
The watercraft will become easier to balance
as the speed increases, because jet thrust
provides stability as well as directional control.
EJU33124Boarding and starting in deep water
WARNING
EWJ01260
Be sure the operator have practiced
boarding from the water while still close to
shore before riding. A person who has
made many unsuccessful attempts to get
back on the watercraft may become fa-
tigued and suffer from exposure, increas-
ing the risk of injury and drowning.
(1) Swim to the rear of the watercraft. Attachthe engine shut-off cord (lanyard) to your left wrist, and then attach the clip to the
engine shut-off switch.
(2) Grip the handlebars with both hands. Pull your body up onto the riding tray and bal-
ance there, using your elbows on the
gunwales for leverage.
(3) Look in all directions, start the engine, and then begin to accelerate.
(4) Continue to pull your body up onto the watercraft as the watercraft speed in-
creases.

(5) Bring your knees up onto the riding trayand change to a kneeling position as
soon as you can do so.
(6) Move as far forward as possible without interfering with the movement of the han-
dlebars. Keep your body perpendicular to
the water, with your weight forward and
low.
(7) Once the bow drops, and the watercraft has leveled out in the water and reached
planing speed, back off the throttle and
select your desired speed.
TIP:
●The watercraft will become easier to bal-
ance as the speed increases, because jet
thrust provides stability as well as direction-
al control.
●It will take longer for a heavy operator to
reach planing speed than it will for a light
operator.
EJU33204Capsized watercraft
WARNING
EWJ00671
Improper uprighting can cause injury.
●Be sure to shut the engine off by pulling
on the engine shut-off cord (lanyard) to
remove the clip from the engine shut-off
switch.
●Do not put your hands in the intake
grate.
If the watercraft capsizes, turn it over immedi-
ately.
To upright the watercraft:
(1) Remove the clip from the engine shut-offswitch.
(2) Swim to the rear of the watercraft. Turn the watercraft over clockwise.
If the port (left) side of the capsized wa-
tercraft is tilting up, push down on the
gunwale so that the port (left) side is
down before turning the watercraft clock-
wise. NOTICE: Do not turn the water-
craft over counterclockwise,
otherwise water can enter the engine,
which can result in severe damage.
[ECJ00541]
(3) Start the engine and operate the water- craft at planing speed to drain the bilge
water in the engine compartment. (See
page 30 for information on draining the
bilge water. If the engine does not start,

see “Towing the watercraft” on page 68
or “Submerged watercraft” on page 68.)
NOTICE: Do not run the engine at full
throttle for at least 1 minute after the
engine has been restarted. Bilge water
in the engine compartment can splash
into the engine, which can result in se-
vere damage.
[ECJ00553]
EJU33302
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.
[EWJ00601] 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.
[ECJ00472]
(4) Get off the watercraft and pull it up on the beach.
EJU37193Operating 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.)
EJU41060After removing the watercraft from the
water
NOTICE
ECJ01360
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 the cooling water passag-
es.
To discharge water from the cooling water
passages:
(1) Make sure that the area around the wa-
tercraft is clear, and then start the engine.
(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.

WARNING
EWJ00320
Always turn the fuel cock knob to “OFF”
when storing the watercraft, otherwise
fuel could leak out into the engine or en-
gine compartment, which would create a
fire hazard.
Storage for long periods of time, such as win-
ter storage, requires preventive maintenance
to ensure against deterioration. It is advisable
to have the watercraft serviced by a Yamaha
dealer prior to storage.
However, the following procedures can be
performed easily by the owner.
EJU40762Cleaning
(1) Flush the cooling water passages. (Seepage 50 for information on flushing the
cooling water passages.)
TIP:
If you will be storing the watercraft for a pro-
longed period, such as winter storage, top off
the fuel tank with fresh gasoline and add fuel
stabilizer and conditioner to the fuel tank ac-
cording to the manufacturer’s instruction be-
fore starting the engine.
(2) Clean the watercraft. (See page 51 for in-formation on cleaning the watercraft.)
Wax the hull with a non-abrasive wax.
