Pre-operation check pointsEJU44551Pre-launch checks
Perform the pre-launch checks in the pre-op-
eration checklist while the watercraft is on
land.
To perform the pre-launch checks:
(1) Remove the seat, seat storage compart-ment, and fire extinguisher holder. (See
page 36 for seat removal and installation
procedures, page 40 for information on
the seat storage compartment, and page
40 for information on the fire extinguisher
holder.)
(2) Perform the checks and make sure that there are no malfunctioning items or oth-
er problems.
(3) After completing these checks, securely install the seat storage compartment, fire
extinguisher holder, and seat in their
original positions.
EJU32334Engine compartment checkEWJ00462
Failure to ventilate the engine compart-
ment could result in a fire or explosion. Do
not start the engine if there is a fuel leak.
Ventilate the engine compartment. Leave the
engine compartment open for a few minutes
to allow any fuel vapors to escape.
Make sure that there is no damage inside the
engine compartment.
EJU34215Fuel system checksEWJ00382
Leaking fuel can result in fire or explosion.
Check for fuel leakage regularly.
If any fuel leakage is found, the fuel sys-
tem must be repaired by a qualified me-
chanic. Improper repairs can make the
watercraft unsafe to operate.
Make sure that there is no damage, leakage,
or other problem in the fuel system.
Check:
Fuel filler cap and seal for damage
Fuel tank for damage and leakage
Fuel hoses and joints for damage and leak-
age
Fuel tank breather hose for damage and
leakage
EJU36875Fuel level check
Check the fuel level in the fuel tank.
Add fuel if necessary. (See page 41 for infor-
mation on filling the fuel tank.)
EJU32424Water separator check
Make sure that no water has collected in the
water separator. If water has collected in the
water separator, drain it. (See page 26 for in-

EJU44252Stern drain plug checks
Loosen the stern drain plugs and remove
them, and then make sure that the plugs and
O-rings on the plugs are not damaged and
that there is no foreign material on the
threads or O-rings on the plugs. NOTICE:
Before installing the stern drain plugs,
clean the drain plug threads and the O-
rings on the plugs to remove any foreign
materials, such as dirt or sand. Otherwise,
the stern drain plugs could be damaged,
allowing water to enter the engine com-
partment. Check the O-rings on the stern
drain plugs and make sure that the plugs
are tightened securely before launching
the watercraft. Otherwise, water may
flood the engine compartment and cause
the watercraft to submerge.
[ECJ00364]

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

someone should make sure that waves do
not push the watercraft into the trailer.
EJU43582Starting 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

EWJ01971
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.
EX SPORT: Do not use the reverse func-
tion to slow down or stop the watercraft
as it could cause you to lose control, be
ejected, or impact the handlebars.
EX DELUXE / EX LIMITED: To avoid
rear-end collisions while operating the
watercraft, check behind you before us-
ing the RiDE lever to slow down or stop
the watercraft.
EJU44682Operating the watercraft in reverse or
neutral (EX SPORT / EX DELUXE / EX
LIMITED)
Operating in reverse (EX SPORT)

system.) Make sure that there are no obstacles or peo-
ple behind you before shifting into reverse.
TIP
This model is not equipped with a neutral
function.
Operating in reverse (EX DELUXE / EX
LIMITED) 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
