Pre-operation check points EJU41311Pre-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 seats and watertight storage
compartment. (See page 41 for seat re-
moval and installation procedures and
page 46 for information on the watertight
storage compartment.)
(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 watertight storage compart-
ment and seats in their original positions.
EJU32333Engine compartment check
WARNING
EWJ00461
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.
EJU34214Fuel system checks
WARNING
EWJ00381
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
EJU36874Fuel level check
Check the fuel level in the fuel tank.
Add fuel if necessary. (See page 49 for infor-
mation on filling the fuel tank.)
EJU32423Water 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 31 for in-
formation on draining the water separator.)

eral times to make sure that operation is
smooth and unrestricted throughout the
whole range, and that the free play is not ex-
cessive.

right and left to make sure that the jet thrust
nozzle moves as the handlebars are turned,
and that there is no difference between theright and left fully turned positions of the jet
thrust nozzle.

make sure that operation is smooth through-
out the whole range. Also, make sure that the
throttle lever returns automatically to its fully
closed (idle) position when released.Face the handlebars straight ahead with the
handlebars in the lowest position and the
throttle lever in the fully closed (idle) position,
and then make sure that there is the proper
amount of throttle lever free play when the
throttle lever is in the fully closed (idle) posi-
tion. (See page 30 for telescopic steering sys-
tem operation procedures.)

EJU32663Engine shut-off cord (lanyard) check
Make sure that the engine shut-off cord (lan-
yard) is not damaged. If the cord is damaged,
replace it. WARNING! Never try to repair
the engine shut-off cord (lanyard) or tie it

them, and then make sure that the plugs are
not damaged and that there is no foreign ma-
terial on the threads. NOTICE: Before in-
stalling the stern drain plugs, clean the
drain plug threads 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. Make sure that the stern drain
plugs are tightened securely before
launching the watercraft. Otherwise, water
may flood the engine compartment and
cause the watercraft to submerge.

EJU36345Starting the engine on water
WARNING
EWJ01530
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 inju-
ry.
To start the engine:
(1) If the lock mode is selected for the
Yamaha Security System setting, select
the unlock mode. (See page 27 for
Yamaha Security System setting proce-
dures.)
(2) Move the watercraft to an area that is free
from weeds and debris, and has a water
depth of at least 60 cm (2 ft) from the bot-
tom 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 in-
take, causing impeller damage and en-
gine overheating.

EJU33169Boarding with passenger(s)
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.
The heavier the total weight of the operator
and passenger(s), 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.
