squeezed. (See page 33 for Yamaha Security
System lock and unlock mode selection pro-
cedures.)
EJU31210Throttle lever
Squeeze the throttle lever to increase engine
speed.
Release the throttle lever to decrease engine
speed or to return it to the idle position.
EJU31240Cooling water pilot outlets
This watercraft is equipped with cooling water
pilot outlets.
When the engine is running, cooling water is
circulated in the engine, and then it is dis-
charged from the pilot outlets.
To check for proper operation of the cooling
system, check that water is being discharged
from the port (left) pilot outlet. If water is not
being discharged from this outlet, cooling wa-
ter may not be circulating in the engine. Whenthis occurs, stop the engine and check for the
cause. (See pages 40 and 94 for more infor-
mation.)
NOTE:

If the cooling water passages are dry, it will
take about 60 seconds for the water to
reach the outlet after the engine is started.

Water discharge may not be constant at
idle, therefore, open the throttle a little to
check that water discharges properly.

Water discharge may not be constant at the
starboard (right) pilot outlet, however, if it is
constant at the port (left) pilot outlet, the
cooling system is operating normally.
EJU31260Steering system
Your watercraft can be steered by turning the
handlebars in the direction you wish to travel.
When the handlebars are turned, the angle of
the jet thrust nozzle is changed, and the direc-
tion of the watercraft is changed accordingly.
Since the strength of the jet thrust determines1Throttle lever

EJU35122Oil pressure warning indicator
If the oil pressure does not rise to specifica-
tion, the “WARNING” indicator light and the oil
pressure warning indicator begin to blink, and
the buzzer sounds intermittently. At the same
time, the engine speed is limited to help pre-
vent damage.
If this occurs, reduce the engine speed, return
to shore, and then check the engine oil level.
(See page 53 for engine oil level checking
procedures.) If the oil level is low, add enough
engine oil to raise it to the proper level. If the
oil level is sufficient, have a Yamaha dealer
check the watercraft.
NOTE:
Press any button on the multifunction informa-
tion center to stop the buzzer.
EJU36401Engine overheat warning indicator
This model is equipped with an engine over-
heat warning system.
If the engine starts to overheat, the engine
overheat warning system will be activated
and, in some cases, the warning system will
cut the ignition to the engine.
If the “WARNING” indicator light and the en-
gine overheat warning indicator begin to blink,
and the buzzer sounds intermittently, immedi-ately reduce the engine speed and return to
shore.
If the “WARNING” indicator light and the en-
gine overheat warning indicator come on, and
the buzzer sounds continuously, the warning
system will cut the ignition. The engine cannot
be started until it cools down, so it may be
necessary to have the watercraft towed back
to the shore. (See “Towing the watercraft” on
page 97 for towing procedures.)
After the engine cools down, start the engine,
and then check for water discharge at the port
(left) cooling water pilot outlet while the engine
is running. If there is no discharge of water,
shut the engine off, and then check the intake
grate and impeller for clogging.
WARNING
EWJ00050
Before attempting to remove weeds or de-
bris from the intake grate or impeller, shut
the engine off and remove the clip from the

Before operating this watercraft, perform the checks in the following check list. See the accom-
panying 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.

Operation

EJU32280Pre-operation check points EJU32330Engine compartment
Ventilate the engine compartment before
each use.
To ventilate the engine compartment, remove
the seats. (See page 24 for seat removal and
installation procedures.) Leave the engine
compartment open for a few minutes to allow
any fuel vapors to escape.
While the engine compartment is open, check
for loose electrical connections.
WARNING
EWJ00460
Failure to ventilate the engine compart-
ment could result in a fire or explosion. Do
not start the engine if there is a fuel leak or
a loose electrical connection.
EJU32350Hull and deck
Check the hull and deck for cracks and other
damage. If any damage is found, have a
Yamaha dealer repair the watercraft.
EJU32380Fuel level
Check the fuel system for leakage, cracks,
and malfunctions before each use. (See page
83 for check points and correct procedures.)
(1) Remove the fuel tank filler cap to release
any pressure that might have built up in
the fuel tank.(2) Remove the seats. (See page 24 for seat
removal and installation procedures.)
(3) Check the fuel level in the fuel tank and
replenish if necessary. (See page 50 for
filling procedures.)
(4) Install the fuel tank filler cap and the
seats.
EJU32411Engine oil level
Check the engine oil level before each use.
CAUTION:
ECJ00390

When checking the engine oil level on
water, be careful of other watercraft,
boats, swimmers, and obstacles. The
water current and wind can cause the
watercraft to move and lead to a colli-
sion.

When checking the engine oil level on
land, supply water to the cooling water
passages. (See page 76 for procedures
on supplying water.)

Make sure that the engine has enough
oil, but do not overfill it. If there is too lit-
tle oil, the engine can be damaged. If
there is too much oil, the air filter can be-
come saturated with oil, permanently
damaging the filter and reducing engine
performance. Follow the checking pro-
cedure carefully.

Make sure that debris and water do not
enter the oil tank filler hole. Debris and
water in the engine oil can cause serious
engine damage.
To check the engine oil level:
(1) Place the watercraft in a horizontal posi-
tion or launch the watercraft, and then
start the engine.
(2) Run the engine at trolling speed for 6 min-
utes or more, and then stop the engine.

shifted from neutral to bow up or bow
down.
If the mechanism does not work properly,
have a Yamaha dealer service it.
EJU32650Jet intake
Carefully check the jet intake for weeds, de-
bris, or anything else that might restrict the in-
take of water. If the jet intake is clogged,
cavitation could occur, reducing jet thrust, and
possibly damaging the jet pump.
In some cases, the engine may overheat be-
cause of lack of cooling water, and damage to
the engine could result. Cooling water is fed to
the engine by the jet pump. (See page 94 for
jet intake cleaning procedures.)
WARNING
EWJ00470

Keep away from the intake grate while
the engine is on. Items such as long hair,
loose clothing, or PFD straps can be-come entangled in moving parts, result-
ing 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 in-
take.
EJU32660Engine shut-off cord
Check that the engine shut-off cord is not
frayed or broken. If the cord is damaged, re-
place it; never try to repair it or tie it together.
