Engine overheat warning
system
This model is equipped with an engine
overheat warning system.
If the engine starts to overheat, the warn-
ing light, the indicator for the water tempera-
ture symbol, and “W. T E M P” display begin to
blink, the buzzer sounds, and the engine
speed will be limited to about 3,400 r/min.
When this occurs, check for water dis-
charge at the cooling water pilot outlet. If
there is no discharge of water, reduce the
engine speed and beach the watercraft, and
then check the intake grate and impeller for
clogging.
WARNING@ Before attempting to remove weeds or
debris from the intake grate or impeller,
shut the engine off and remove the clip
from the engine shut-off switch. Severe
injury or death could result from coming
in contact with the rotating parts of the
jet pump.
@
CAUTION:@ If you cannot locate and correct the
cause of the overheating, consult a
Yamaha dealer. Continuing to operate at
higher speeds could result in severe
engine damage.
@
NOTE:@ Press any button on the multifunction meter
to stop the buzzer.

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
plugs and caps, otherwise the meter
may function erratically.
@
NOTE:@ The demonstration mode display starts
showing after the engine starts. Then all dis-
plays light up and the buzzer sounds twice.
The meter will operate normally after a few
seconds. The current display will continue to
operate for 30 seconds after the engine
stops.

Oil warning indicator
If the oil remaining in the tank drops to
about 1.4 L (0.37 US gal, 0.31 Imp gal) or
the oil filter is clogged, the lowest oil level
segment, the oil warning indicator, “OIL” and
the warning light begin to blink. The buzzer
also starts sounding intermittently.
If the oil warning indicator begins to blink,
refill with engine oil as soon as possible.
NOTE:@ If the warning indicator blinks with adequate
oil in the tank, check the oil filter for clog-
ging.

Engine overheat warning
indicator
If the engine starts to overheat, the over-
heat warning indicator, “W. T E M P” and the
warning light begin to blink. The buzzer also
starts sounding intermittently.
Refer to “Engine overheat warning sys-
tem” on page 2-17.

Jet unit
Carefully check the jet intake for weeds,
debris, or anything else that might restrict
the intake of water. If the intake is clogged,
cavitation could occur, reducing jet thrust,
and possibly damaging the jet pump.
In some cases, the engine may overheat
because of lack of cooling water, and dam-
age to the engine could result. Engine cool-
ing water is fed to the engine by the jet
pump. (See page 5-4 for jet intake cleaning
procedures.)
WARNING@ Keep away from intake grate while
engine is on. Items such as long hair,
loose clothing, or PFD straps can
become entangled in moving parts
resulting in severe injury or drowning.
Stop the engine and remove the clip
from the engine shut-off switch before
removing any debris or weeds, which
may have collected around the jet
intake.

Engine shut-off cord (lanyard)
Check that the engine shut-off cord is not
frayed or broken. If the cord is damaged,
replace it; never try to repair it or tie it
together.

CAUTION:@ Be sure to remove the clip from the
engine shut-off switch, otherwise the
engine will overheat and engine damage
may occur.
@
1. Shut the engine off by removing the clip
from the engine shut-off switch.
2. Swim to the rear of the watercraft. Climb
onto the right side of the capsized water-
craft and place both feet on the rub rail
near the stern.
NOTE:@ If the port (left) side of the capsized water-
craft is tilting upward, first tilt the watercraft
so the port (left) side is down by using your
weight to press down on the rub rail.
@
3. Grasp the ride plate with your left hand
and place your right hand under the
intake grate.
4. Lean backwards and forcefully pull the
watercraft clockwise until it is upright.
CAUTION:@ Do not turn the watercraft over counter-
clockwise, otherwise water may leak into
the carburetor and engine and cause
damage.
@
5. Start the engine, and then head for
shore to inspect the engine for water
damage.
CAUTION:@ If the watercraft has been capsized for
5 minutes or more, air may have entered
the oil injection system. Leave the engine
off, or operate only at trolling speed, for
10 minutes after the watercraft has been
turned right-side up. This will allow any
air to bleed off.

Post-operation checks
Always perform the following post-opera-
tion checks after operating the watercraft.
1. Remove the watercraft from the water.
2. Wash down the hull, handlebars, and jet
unit with fresh water.
3. Remove the seat and check the engine
compartment for water. To drain excess
water, remove the stern drain plugs, then
raise the bow of the watercraft enough to
allow water in the bilge to drain out.
NOTE:@ This watercraft is equipped with an auto-
matic bilge-draining system that removes
water from the engine compartment while
you are underway. However, some residual
water will remain.
@
4. Put the watercraft in a horizontal posi-
tion.
5. Flush the cooling system to prevent it
from clogging with salt, sand, or dirt.
(See page 4-1 for flushing the cooling
system procedures.)
6. Drain residual water from the exhaust
system by alternately squeezing and
releasing the throttle lever for 10 to
15 seconds while the engine is running.
CAUTION:@ Do not attempt to run the engine at full
throttle or for more than 15 seconds
while the watercraft is out of the water,
otherwise the engine may overheat or
seize.

Storage
WARNING@ Always place the fuel cock knob in the
“OFF” position when storing the water-
craft, otherwise fuel could leak out into
the engine or engine compartment,
which would create a fire hazard.
@
Storage for prolonged periods of time,
such as winter storage, requires preventa-
tive maintenance to ensure against deterio-
ration. It is advisable to have the watercraft
serviced by a Yamaha dealer prior to stor-
age. However, the following procedures can
be performed by the owner.
EJU01088
Flushing the cooling system
Flushing the cooling system is essential
to prevent the cooling system from being
clogged with salt, sand, or dirt.
CAUTION:@ Do not supply water to the cooling
water passages when the engine is not
running. The water could flow back
through the muffler into the crankcase
causing severe engine damage.
Do not run the engine for more 15 sec-
onds without supplying water, other-
wise the engine may overheat.
