EJU40212Riding position
Operator riding position
The operator should grip the handlebars firm-
ly with both hands and sit astride the seat
with both feet on the floor of the footwell.
Passenger riding position
The passenger(s) should hold on firmly, either
to the person in front of them or to the hand-
grip provided, and sit astride the seat with
their feet on the floor of the footwell. Never al-
low a passenger to ride in front of the opera-
tor. (See page 16 for information on the riding
position when pulling a wakeboarder or wa-
ter-skier.)
EJU32804Launching the watercraft
When launching the watercraft, make sure
that there are no obstacles around you.
If the watercraft is launched from a trailer,
someone should make sure that waves do
not push the watercraft into the trailer.
EJU47151Starting the engine on waterEWJ01532
Do not apply throttle when anyone is at the
rear of the watercraft. Turn the engine off
or keep it at idle. Water and debris exiting
the jet thrust nozzle can cause severe in-
jury.
To start the engine:
(1) Move the watercraft to an area that isfree from weeds and debris, and has a
water depth of at least 60 cm (2 ft) 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, otherwise
pebbles or sand could be sucked into
the jet intake, causing impeller dam-
age and engine overheating.
[ECJ00473]
(2) Attach the engine shut-off cord (lanyard) to your left wrist, and then attach the clip
to the engine shut-off switch. (See page
24 for information on operating the en-
gine shut-off switch.) WARNING! Check
that the engine shut-off cord (lanyard)
is attached correctly. If the engine
shut-off cord (lanyard) is not attached
correctly, it may not pull free when the
operator falls off, allowing the water-

proximately 100 m (330 ft) after the throttle le-
ver is released or the engine is stopped,
although this distance will vary depending on
many factors, including gross weight, water
surface conditions, and wind direction.
If the RiDE lever is squeezed to slow down,
the stopping distance is approximately 30%
shorter than when the RiDE lever is not used.
However, this distance will vary depending
on many factors, including gross weight, wa-
ter surface conditions, and wind direction.
EWJ01794
Allow adequate stopping distance. Stay
far enough away from others so you can
always safely coast to a stop.
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.
To avoid rear-end collisions while oper-
ating the watercraft, check behind you
before using the RiDE lever to slow
down or stop the watercraft.
EJU43447Operating the watercraft in reverse or
neutral
Operating in reverse
When the RiDE lever is squeezed, the “R” (re-
verse) shift indicator will be displayed and the
watercraft will move in reverse. (See page 27
for shift system operation procedures.)
Make sure that there are no obstacles or peo-
ple behind you before shifting into reverse.
TIP
This model is equipped with a function which
limits the engine speed in reverse.
Operating in neutral
When the RiDE lever is squeezed lightly and
released, the “N” (neutral) shift indicator will
be displayed and the watercraft will stop in its
current location. (See page 27 for shift sys-
tem operation procedures.)

(7) Run the engine at idling speed for about3 minutes watching the engine condition.
If the engine stops while flushing, turn
the water supply off immediately and
perform the procedure again from step 6.
NOTICE: Do not supply water to the
cooling water passages when the en-
gine is not running. The water could
flow back through the muffler into the
engine, causing severe engine dam-
age.
[ECJ00123]
(8) Turn the water supply off.
(9) Discharge the remaining water out of the cooling water passages by alternately
squeezing and releasing the throttle lever
quickly for 10 to 15 seconds.
(10) Stop the engine.
(11) Remove the garden hose adapter, and then securely install the flushing hose
connector cap by tightening it until it
stops.
(12) Securely install the seat storage com- partment and seat in their original posi-
tions.
EJU44770Cleaning the watercraft
(1) Remove the seat and fire extinguisherholder. (See page 36 for seat removal
and installation procedures and page 40
for information on the fire extinguisher
holder.) (2) If the watercraft will be stored for a week
or more, rustproof the internal engine
components to help prevent corrosion.
(See page 73 for information on rust-
proofing the internal engine compo-
nents.)
(3) Rinse the engine and engine compart- ment with a small amount of water.
NOTICE: Do not use high-pressure
water when rinsing the engine or en-
gine compartment as severe engine
damage could result.
[ECJ00572]
(4) Drain the water from the engine com- partment. (See page 45 for information
on draining the bilge water.)
(5) Wipe the engine and engine compart- ment with a dry cloth.
(6) Wash down the hull, deck, and jet pump with fresh water.
(7) Wipe the hull, deck, and jet pump with a dry cloth.
(8) Wipe all vinyl and rubber components, such as the seat and engine compart-
ment seals, with a vinyl protectant.
(9) To minimize corrosion, spray metallic parts of the hull, deck, and engine with a
rust inhibitor.
(10) Allow the engine compartment to air dry completely before installing the seat.
(11) Securely install the fire extinguisher hold- er and seat in their original positions.
EJU3368DBattery care

EJU33495
Long-term storageEWJ00332
Always place the watercraft upright in a
horizontal position when storing it, other-
wise fuel could leak out into the engine or
engine compartment, which could 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.
EJU40763Cleaning
(1) Flush the cooling water passages. (Seepage 69 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 70 for in-formation on cleaning the watercraft.)
Wax the hull with a non-abrasive wax.

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.
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.
