Fuel and oil
This engine uses Yamaha’s oil injection
system, which provides superior lubrication
by ensuring the proper oil ratio for all operat-
ing conditions. No fuel premixing is neces-
sary except during the engine break-in
period. Simply pour gasoline into the fuel
tank and oil into the oil tank.
Gasoline
WARNING
GASOLINE AND ITS VAPORS ARE
HIGHLY FLAMMABLE AND EXPLOSIVE!
●Do not smoke when refueling, and
keep away from sparks, flames, or
other sources of ignition.
●Stop engine before refueling.
●Refuel in a well-ventilated area. Do not
stand or sit on the watercraft while
refueling in case of fire.
●Take care not to spill gasoline. If gaso-
line spills, wipe it up immediately with
dry rags. Always properly dispose of
gasoline-soaked rags.
●Avoid overfilling the fuel tank. Stop fill-
ing when the fuel level just reaches the
bottom of the filler tube. Do not fill up
the filler tube because fuel expands as
it warms up and could overflow.
●Tighten the filler cap securely after
refueling.
●If you should swallow some gasoline,
inhale a lot of gasoline vapor, or get
gasoline in your eyes, get immediate
medical attention.
●If any gasoline spills onto your skin,
immediately wash with soap and
water. Change clothing if gasoline
spills on it.

CAUTION:
Use only fresh gasoline that has been
stored in clean containers.
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.Recommended gasoline:
Regular unleaded gasoline with
a minimum octane rating of
86 (Pump octane number) = (R+M)/2
90 (Research octane number)

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. Also, remove all
seats, so you can watch the fuel level.
(See page 2-6 for hood, and pages 2-4
and 2-5 for seats.)
2. Open the fuel tank filler cap, and slowly
add fuel to the fuel tank.
3. Stop filling when the fuel just reaches the
top of the fuel tank.

2-stroke engine oil
If YAMALUBE 2-W is not available,
another 2-stroke engine oil with an NMMA-
certified TC-W3 rating may be used.Fuel tank capacity:
Total: 50 L (13.2 US gal, 11 Imp gal)
Reserve: 12 L (3.17 US gal, 2.64 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. Open the hood and remove the front
storage compartment. Also, remove all
seat, so you can watch the oil level. (See
page 2-6 for hood, and pages 2-4 and
2-5 for seats.)
2. Open the oil tank filler cap, and very
slowly add engine oil to the oil tank.
3. Stop pouring when the oil just reaches
the bottom of the filler tube.
Oil tank capacity:
3.8 L (1.0 US gal, 0.84 Imp gal)

Pre-operation checks
Pre-operation check list
Before operating this watercraft, perform the checks in the following check list. See the
accompanying text in this chapter for details on how to perform the checks.
WARNING
If any item in the pre-operation check list is not working properly, have it inspected
and repaired before operating the watercraft, otherwise an accident could occur.
NOTE:
Pre-operation checks should be made thoroughly each time the watercraft is used. This pro-
cedure can be completed in a short time. It is worth the time spent to assure safety and reli-
ability.

Pre-operation check points
Engine compartment
Ventilate the engine compar tment before
each use.
To ventilate the engine compartment,
remove all seats and the front storage com-
partment. (See pages 2-4 and 2-5 for front
and rear seat, and 2-13 for front storage
compartment.) Allow the engine compart-
ment to remain open for a few minutes to
allow any fuel vapors to escape. Also, check
for loose electrical connections.
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.
EJU00427-30a
Fuel and oil systems
Check the fuel system for leakage, cracks
or malfunctions before each use. (See page
4-9 for check points and correct proce-
dures.)
1. Remove the fuel tank filler cap to release
any pressure that might have built up in
the fuel tank.
2. Remove all seats and the front storage
compartment. (See pages 2-4 and 2-5
for front and rear seat, and 2-13 for front
storage compartment.)
3. Check the fuel and oil levels in the tanks
and add as necessary. (See pages 3-3
and 3-4 for filling instructions.)

Water separator
Check the water separator 1 for water.
Normally the water separator is empty. The
water separator retains any water entering
through the fuel tank breather hose if the
watercraft is capsized.
If water remains in the water separator,
drain it by removing the drain screw 2.
Install the drain screw again after draining
the water separator.
EJU00433a
Bilge
Check for moisture and fuel residue in the
bilge.
Excessive water in the bilge can splash
into the carburetor and engine which could
cause engine damage.
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.

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.
Make sure that the breather hose is prop-
erly connected and that it is not damaged or
obstructed.
Make sure that the battery is securely
held in place.

Fire extinguisher
Check that there is a full fire extinguisher
on board. The fire extinguisher container 1 is
located on the underside of the rear seat.
(See page 2-4 for rear seat removal proce-
dures.)
To open the fire extinguisher container
cap2, turn it counterclockwise.
After inserting the fire extinguisher, make
sure that the container cap is tightened
securely.
Install the fire extinguisher container on
the seat and secure it with the bands 3.
NOTE:
●See the instructions supplied by the fire
extinguisher manufacturer for checking
the fire extinguisher. Always keep the
extinguisher in the fire extinguisher con-
tainer.
●Always carry a fire extinguisher on board.
A fire extinguisher is not standard equip-
ment with this watercraft. If you do not
have one, contact a Yamaha dealer or a
fire extinguisher dealer to obtain one
meeting the proper specifications.
