2. Turn the fuel cock knob to the “ON” posi-
tion.
NOTE:@ Before starting the watercraft, after it has
been sitting, remove the fuel tank filler cap
to release any built-up pressure in the tank
due to fuel expansion.

3. Attach the clip 1 to the engine shut-off
switch 2. Also, attach the engine shut-
off cord 3 to your left wrist.
WARNING@ Check that the engine shut-off cord is not
frayed or broken, and keep it free from
the handlebars so the engine stops if the
operator falls off. The engine shut-off
cord may not pull free if wrapped around
the handlebars when the operator falls
off, allowing the watercraft to continue to
run and cause an accident.
@
NOTE:@ It is not possible to start the engine with the
clip removed from the engine shut-off
switch.

Transporting
WARNING@ Always place the fuel cock knob in the
“OFF” position when transporting the
watercraft, otherwise fuel could leak out
into the engine or engine compartment,
which would create a fire hazard.
@
When transporting the watercraft on a
trailer, secure the tie downs to the trailer
through the bow eye and stern rope holes.
CAUTION:@ Do not route ropes or tie downs over the
seat, as they may leave permanent marks
on the seat’s surface. Also, wrap the
ropes or tie downs with towels or rags
where they touch the body of the water-
craft to avoid scratching or damage.

Storage
WARNING@ Always place the fuel cock knob in the
“OFF” position when storing the water-
craft, otherwise fuel could leak out into
the engine or engine compartment,
which would create a fire hazard.
@
Storage for prolonged periods of time,
such as winter storage, requires preventa-
tive maintenance to ensure against deterio-
ration. It is advisable to have the watercraft
serviced by a Yamaha dealer prior to stor-
age. However, the following procedures can
be performed by the owner.
EJU01088
Flushing the cooling system
Flushing the cooling system is essential
to prevent the cooling system from being
clogged with salt, sand, or dirt.
CAUTION:@
Do not supply water to the cooling
water passages when the engine is not
running. The water could flow back
through the muffler into the crankcase
causing severe engine damage.

Do not run the engine for more
15 seconds without supplying water,
otherwise the engine may overheat.

Fuel system
Draining the fuel system prevents buildup
of varnishes and other harmful deposits that
result when gasoline sits for a prolonged
period of time.
WARNING@ Gasoline is highly flammable and explo-
sive. A fire or explosion can cause
severe injury or death. Shut the engine
off. Drain in well-ventilated areas away
from flames or sparks. Do not smoke.
Avoid spilling gasoline. Wipe up spilled
gasoline immediately.
@
To drain the fuel system:
1. Place the fuel cock knob in the “OFF”
position.
2. Drain the fuel tank using a siphon.
