Gasohol
There are two types of gasohol: gasohol
containing ethanol and that containing meth-
anol.
Gasohol containing ethanol can be used
if ethanol content does not exceed 10% and
the fuel meets minimum octane ratings.
Gasohol containing methanol is not rec-
ommended by Yamaha because it can
cause fuel system damage or engine perfor-
mance problems.

Filling the fuel tank
CAUTION:@ Be careful when refueling. Avoid getting
water or other contaminants in the fuel
tank. Contaminated fuel can cause poor
running or engine damage.
@
1. Open the hood and remove the front
storage compartment, to check the fuel
level. (See page 2-20 for front storage
compartment.)
2. Open the fuel tank filler cap, and slowly
add fuel to the fuel tank.
3. Stop filling when the fuel just reaches the
bottom of the filler tube on the fuel tank.
Do not fill into the filler tube, because
fuel could spill out.
Fuel tank capacity:
Total: 60 L (15.9 US gal, 13.2 Imp gal)

Filling the oil tank
WARNING@
Do not add gasoline to the oil tank.
Fire or explosion could result.

Oil in the bilge is a serious fire hazard.
Wipe up any spilled oil immediately.
@
CAUTION:@ Do not allow the oil tank to become com-
pletely empty. If the oil tank becomes
empty the oil injection pump must be
bled to ensure proper oil flow, otherwise
engine damage may occur. If bleeding of
the oil pump is necessary, have a
Yamaha dealer bleed it.
@
1. Remove the seat to watch the oil level.
(See page 2-5 for seat.)
2. Open the oil tank filler cap, and very
slowly add engine oil to the oil tank.
3. Stop filling when the oil just reaches the
top of oil tank visible.
Oil tank capacity:
5.5 L (1.5 US gal, 1.2 Imp gal)

Engine compartment
Ventilate the engine compar tment before
each use.
To ventilate the engine compartment,
remove seat and front storage compart-
ment. (See page 2-5 for seat, and 2-20 for
front storage compartment.) Allow the
engine compartment to remain open for a
few minutes to allow any fuel vapors to
escape. Also, check for loose electrical con-
nections.
WARNING@ Failure to ventilate the engine compart-
ment could result in fire or explosion. Do
not start the engine if there is a fuel leak
or a loose electrical connection.

Bilge
Check for moisture and fuel residue in the
bilge.
This watercraft is equipped with a conven-
tional jet vacuum bilge draining system and
an electric bilge draining system. The elec-
tric bilge draining system is operated when
the engine is running. When excess water
reaches the water inlet of the electric bilge
pump, the water is discharged via the
exhaust passage from the jet thrust nozzle.
A small quantity of water will remain in the
bilge and should be removed manually. To
remove any residual water, perform the fol-
lowing procedure.
To remove water from the bilge:
1. Remove the stern drain plugs.
2. Raise the bow of the watercraft until the
water drains.
3. After the water has drained, wipe the
bilge with dry rags to make sure that the
bilge is thoroughly dry.
4. Install the drain plugs.
CAUTION:@
Make sure that the stern drain plugs
are tightened securely before launch-
ing the watercraft.

Clean any foreign materials, such as
dirt or sand, from the drain plug
threads before installing the drain
plugs.

CAUTION:@
Make sure that the stern drain plugs
are tightened securely before launch-
ing the watercraft. Otherwise, water
may flood the engine compartment
and cause the watercraft to submerge.

Clean any foreign materials, such as
dirt or sand, from the drain plug
threads before installing the drain
plugs. Otherwise, the drain plugs may
be damaged and water may enter the
engine compartment.

Battery
Check the battery condition and the elec-
trolyte level.
Check that the battery leads are tightened
securely and there is no corrosion on the
battery terminals.
WARNING@
The battery must always be fully
charged and in good condition. Loss
of battery power may leave you
stranded. Never operate the watercraft
if the battery does not have sufficient
power to start the engine or if it shows
any other signs of decreased power.

Be sure to connect the breather hose
to the battery. Fire or explosion could
result if the breather hose is damaged,
obstructed, or not connected properly.
@
Make sure that the battery is securely
held in place.

Throttle
Squeeze and release the throttle lever
several times to make sure that there is no
hesitation in its travel. It should be smooth
over the complete range, and spring back to
the idle position when released.
WARNING@ Before starting the engine, always check
the operation of the throttle lever.
@
EJU10570
Steering system
Check for looseness in the handlebars.
Turn them as far as possible to the right
and left to make sure that operation is
smooth and unrestricted throughout the
whole range. Make sure that the jet thrust
nozzle also changes directions as the han-
dlebars are turned, and that there is no free
play between the handlebars and the jet
thrust nozzle.
