Oil level warning lamp
If the oil remaining in the tank drops to
about 1.2 L (0.31 US gal, 0.26 Imp gal) or
the oil filter is clogged, the oil level warning
lamp begins to blink.
If the oil level warning lamp begins to
blink, refill with engine oil as soon as possi-
ble.
NOTE:
●The lamp will light up for 2 seconds after
starting the engine to check the lamp
operation.
●If the warning lamp blinks with adequate
oil in the tank, check for a clogged oil fil-
ter.

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.

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.

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.)
