EJU36351Boarding alone
(1) Swim to the rear of the watercraft and
place both hands on the boarding plat-
form, pull yourself up, and then grasp the
handgrip with one hand.
(2) Pull yourself up to a kneeling position on
the platform, and then move to the seat
and sit astride.
(3) Attach the engine shut-off cord (lanyard)
to your left wrist, and then attach the clip
to the engine shut-off switch.
(4) Grip the handlebars with both hands,
place both feet on the floor of the footwell,start the engine, and then look in all direc-
tions before starting off.
TIP:
This watercraft is equipped with a reboarding
step, which you can lower to make reboarding
easier. The step returns automatically to the
up position after you have boarded.
EJU33164Boarding with passengers
WARNING
EWJ00660
Severe internal injuries can occur if water
is forced into body cavities as a result of
being near the jet thrust nozzle. Do not ap-
ply throttle until the passengers are seated
with their feet on the floor of the footwell
and are securely holding on to the person
in front of them or to the handgrip provid-
ed.
TIP:
The heavier the total weight of the operator
and passengers, the more difficult it will be to
balance the watercraft. Do not operate the
watercraft when the total weight exceeds 240
kg (530 lb) including any cargo.

(1) Climb on board as noted in the previous
section, and sit astride the seat.
(2) Attach the engine shut-off cord (lanyard)
to your left wrist, and then attach the clip
to the engine shut-off switch.
(3) Have the passengers move to the rear of
the watercraft.
(4) Have a passenger board and sit astride
the seat. If a second passenger is board-
ing, have him or her follow the same pro-
cedure. When a passenger is boarding,both the passengers and the operator
should try to balance the watercraft.
(5) Check that the passengers have their
feet on the floor of the footwell and are
securely holding on to the person in front
of them or to the handgrip provided. Nev-
er allow a passenger to ride in front of the
operator.
(6) Start the engine, look in all directions, and
then accelerate to planing speed.
To board when it is difficult to balance the wa-
tercraft at a standstill:
(1) While the passengers are steadying the
watercraft, pull yourself up onto the
boarding platform into a kneeling posi-

(5) Flush the cooling system to prevent it
from clogging with salt, sand, or dirt. (See
page 74 for flushing procedures.)
(6) 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.
[ECJ00571]
(7) Wipe the engine and engine compart-
ment dry with a clean cloth (repeat step 3,
if necessary).
(8) Wipe the hull, handlebars, and jet unit dry
with a clean cloth.
(9) Spray a rust inhibitor on metallic parts to
minimize corrosion.
(10) Allow the engine compartment to air dry
completely before installing the seats.
EJU33462
Transporting
Before putting the watercraft on a trailer or
transporting it, be sure to put the shift lever in
the forward position. When transporting the
watercraft on a trailer, secure the tie downs to
the trailer through the bow eye and stern
eyes. NOTICE: Do not attach ropes or tie
downs to any part of the watercraft other
than the bow eye and stern eyes to secure
the watercraft to the trailer. Otherwise, the
watercraft may be damaged. Wrap the
ropes or tie downs with towels or rags
where they touch the body of the water-
craft to avoid scratches or damage. Do not
transport the watercraft with the shift lever
in the reverse position. Otherwise, the re-
verse gate may hit an obstacle, which
could cause damage.

Storage
WARNING
EWJ00330
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 by the owner.
EJU37202Flushing the cooling system
Flushing the cooling system is essential to
prevent it from clogging with salt, sand, or dirt.
(1) Place the watercraft in a horizontal posi-
tion.
(2) Remove the rear seat and seat storage
compartment. (See page 25 for seat re-
moval and installation procedures.)
(3) Remove the flushing hose connector
cap, and then insert the garden hose
adapter into the flushing hose connector
and turn it until it is securely connected.(4) Connect the garden hose adapter to a
water tap using a garden hose.
TIP:
A garden hose is not included.
(5) Start the engine, and then immediately
turn the water supply on until water flows
out continually from the jet thrust nozzle.
NOTICE: Do not run the engine for
more than 15 seconds without supply-
ing water or over 4000 r/min on land,
otherwise the engine could overheat.
[ECJ01050]
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.
(6) Run the engine at idling speed for about
3 minutes watching the engine condition.
If the engine stops while flushing, turn the
water supply off immediately and repeat
the above steps. NOTICE: Do not sup-
ply water to the cooling water passag-
es when the engine is not running. The
water could flow back through the
muffler into the engine, causing se-
vere engine damage.
[ECJ00122]
(7) Turn the water supply off, and then force
the remaining water out of the cooling

EJU37610Cleaning and adjusting the spark
plugs
WARNING
EWJ00350
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.
The spark plug is an important engine compo-
nent and is easy to inspect. The condition of
the spark plug can indicate something about
the condition of the engine. For example, if
one spark plug has a distinctly different color,
the engine could require servicing. Do not at-
tempt to diagnose any problems yourself.
Have a Yamaha dealer service the watercraft.Remove and inspect the spark plugs periodi-
cally; heat and deposits will cause the spark
plugs to slowly break down and erode. If elec-
trode erosion becomes excessive, or if carbon
and other deposits are excessive, replace the
spark plug with the specified plug.
To remove a spark plug:
(1) Remove the seats. (See page 25 for seat
removal and installation procedures.)
(2) Open the plastic tie that is securing the
breather hose.
TIP:
Be careful not to drop the plastic tie into the
engine compartment.

(3) Remove the engine cover screws, and
then remove the engine cover.
(4) Remove the spark plug cap bolts, and
then remove the spark plug cap.
NOTICE: Do not use any tools to re-
move or install the spark plug cap,
otherwise the ignition coil coupler
could be damaged. The spark plug
cap may be difficult to remove be-
cause the rubber seal on the end of
the cap fits tightly. To remove the
spark plug cap, simply twist it back
and forth while pulling it up; to install
it, twist it back and forth while pushing
it down.
[ECJ00211]
(5) Remove the spark plug.
Measure the spark plug gap with a wire
thickness gauge. Replace the spark plug
or adjust the gap to specification if neces-
sary.
To install a spark plug:
(1) Clean the gasket surface.
(2) Wipe any dirt from the threads of the
spark plug.
(3) 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.
(4) Wipe off any water on the spark plug or
inside the spark plug cap, and then install
the cap. Push the spark plug cap down
until it is securely installed, and then in-

be routed under the engine cover, and
then install the cover and engine cover
screws.

hose toward the bow until it stops, andthen secure the breather hose to the en-
gine cover by closing the plastic tie.
