Do not run the engine over 4,000 r/min
to check the meter for operation on
land. The engine could overheat or the
catalytic converter could result in seri-
ous damage.

Use the specified resistor-type spark

Oil warning indicator
If the oil remaining in the tank drops to
about 1.7 L (0.45 US gal, 0.37 Imp gal) or
the oil filter is clogged, the oil warning indi-
cator and the warning light begin to blink.
The buzzer also starts sounding intermit-
tently.
If the oil warning indicators begin to blink,
refill with engine oil as soon as possible.
The warning signals will be cleared when
the engine restarts after refilling engine oil.
NOTE:@ If the warning indicators blink with adequate
oil in the tank, have a Yamaha dealer check
the oil filter for dirt and clogs.
@
EJU20042
Check engine warning
indicator
If a sensor malfunction or a short circuit is
detected, the warning light and indicator
begin to blink and the buzzer sounds inter-
mittently.
If this occurs, reduce the engine speed,
return to shore, and have a Yamaha dealer
check the engine.

Engine overheat warning
indicator
If the engine starts to overheat, the warn-
ing light and engine overheat warning indi-
cator begin to blink, and the buzzer sounds
intermittently.
If the watercraft continues to be operated
at higher speeds after the warning system
has been activated, the warning light,
engine overheat warning indicator and the
buzzer will change from intermittently to
continuously on. (See “Engine overheat
warning system” on page 2-12 for further
details.)
The warning signals will turn off when the
engine is started after it has cooled down.
NOTE:@ When the warnings overlap each other, their
priority is as follows:
1. Final overheat warning
2. Fuel level warning
3. Oil level warning
4. Initial overheat warning
5. Exhaust temperature warning
6. Check engine warning

Exhaust temperature warning
indicator
If the exhaust system becomes too hot,
the warning light and exhaust temperature
warning indicator begin to blink, and the
buzzer sounds intermittently. (See “Exhaust
temperature warning system” on page 2-13
for further details.)
The warning signals will turn off when the
engine is started after it has cooled down.

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.
The engine utilizes an electronic fuel
injection system to deliver the optimal air-
fuel mixture ratio required by the engine.
With optimal combustion conditions, this
system is able to increase startability and
improve fuel economy.
EJU19122
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 with
the watercraft in a horizontal position.

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.

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.
EJU11870
2-stroke engine oil
CAUTION:@ Use only YAMALUBE 2-W oil. Using
another oil can seriously damage the cat-
alytic converter and other engine compo-
nents.
@
NOTE:@ YAMALUBE 2-W is developed for this water-
craft and available from a Yamaha dealer.
@
Recommended engine oil:
YAMALUBE 2-W oil only

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)
