Engine stop switch
Push this switch 1 (red button) to stop
the engine normally.
EJU00706
Engine shut-off switch
Insert the clip 1, on the end of the engine
shut-off cord 2, under the engine shut-off
switch 3 (black button). The engine will stop
automatically when the clip is removed from
the switch, such as if the operator falls off
the watercraft.
WARNING
●Always attach the engine shut-off cord
to your wrist and the clip to the engine
shut-off switch BEFORE starting the
engine.
●To prevent accidental starting of the
engine or unauthorized use by chil-
dren or others, always remove the clip
from the shut-off switch when the
engine is not running.

Choke lever
Starting a cold engine requires a richer
air-fuel mixture, which is supplied by the
choke.
Move the lever 1 in direction a to turn
the choke on.
Move the lever in direction b to turn the
choke off.

Bow down
Turn the grip to A or B and the bow will
go down while the watercraft is on plane.
Bow down puts more of the bow in the
water. This gives the watercraft more “hook,”
which enhances turning performance. This
position will also help the watercraft get up
on plane more quickly.
At higher speeds, however, the watercraft
will have greater tendency to “bow steer”
and follow waves and wakes in the water.
Fuel economy and maximum speed are also
reduced.
Bow up
Turn the grip to C or D and the bow will
go up while the watercraft is on plane.
Bow up puts less of the bow in the water.
There is less water resistance, so straight-
ahead acceleration when on plane and top
speed are enhanced.
In some conditions, however, the water-
craft may tend to “porpoise” (hop in the
water). If the watercraft is porpoising,
choose neutral or bow down.

CAUTION:
●Do not run the engine at full throttle or
more than 15 seconds to check the
meter for operation on land. The
engine could overheat.
●Use the specified resistor-type spark
plug and cap, otherwise the meter may
function erratically.

onds. The current display will continue to
operate for 30 seconds after the engine
stops.

EJU00386a
Fuel meter
The fuel meter is provided for convenient
fuel level checking while riding. The fuel
meter has eight segments which show the
amount of fuel remaining in the fuel tank.
NOTE:
The indication of the segments differs on
your operating condition. Use the meter as a
reference.
EJU00390a
Hour meter
The hour meter is provided to make it
easy to follow the maintenance schedule.
The meter shows the hours of engine opera-
tion that have elapsed since the watercraft
was new.
NOTE:
●The elapsed time will be kept even if the
battery terminals have been discon-
nected.
●If the hour meter malfunctions, “____”
display and the warning light will blink.

EJU00716a
Fuel warning indicator
If the fuel remaining in the tank drops to
about 13 L (3.4 US gal, 2.9 lmp gal), the
lowest two fuel level segments, the fuel
warning indicator and the warning light
begin to blink. The buzzer also starts sound-
ing intermittently.
The warning signals will be cleared when
the engine restarts after refilling fuel.
EJU00717a
Oil warning indicator
If the oil remaining in the tank drops to
about 1.7 L (0.45 US gal, 0.37 lmp 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, check the oil filter for clog-
ging.

EJU00718a
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 and
engine overheat warning indicator begin to
blink rapidly, and the buzzer sounds continu-
ously. (See “Engine overheat warning sys-
tem” on page 2-13 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

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.
