EJU30860
Hazard information

Never start the engine or let it run for any
length of time in an enclosed area. Exhaust
fumes contain carbon monoxide, a color-
less, odorless gas that may cause loss of
consciousness and death within a short
time. Always operate the watercraft in an
open area.

Do not start the engine on land if anyone is
behind the watercraft. Hot water and steam
spurting from the exhaust outlet can cause
serious burns.

Do not touch the hot muffler or catalytic
converter during or immediately after en-
gine operation; they can cause serious
burns. In addition, the catalytic converter
becomes hotter after the engine stops be-
fore cooling down.
EJU30890
Watercraft characteristics

Jet thrust turns the watercraft. Releasing
the throttle lever completely produces only
minimum thrust. If you are traveling at
speeds above trolling, you will have rapidly
decreasing ability to steer without throttle.
This model is equipped with the Yamaha
Engine Management System (YEMS) that
includes an off-throttle steering (OTS) sys-
tem. It will activate at planing speeds should
you attempt to steer the watercraft after re-
leasing the throttle lever. The OTS system
assists in turning by continuing to supply
some thrust while the watercraft is deceler-
ating, but you can turn more sharply if you
apply throttle while turning the handlebars.
The OTS system does not function below
planing speeds or when the engine is off.
Once the engine slows down, the watercraft
will no longer turn in response to handlebar
input until you apply throttle again or you
reach trolling speed.
Practice turning in an open area without ob-
stacles until you have a good feel for this
maneuver.

This watercraft is water-jet propelled. The
jet pump is directly connected to the engine.
This means that jet thrust will produce some
movement whenever the engine is running.
There is no “neutral” position.

Keep away from the intake grate while the
engine is on. Items such as long hair, loose
clothing, or PFD straps can become entan-
gled in moving parts, resulting in severe in-
jury or drowning.

Never insert any object into the jet thrust
nozzle while the engine is running. Severe
injury or death could result from coming in

WARNING
EWJ00010

Always attach the engine shut-off cord
to your left wrist and the clip to the en-
gine shut-off switch BEFORE starting
the engine.

To prevent accidental starting of the en-
gine or unauthorized use by children or
others, always remove the clip from the
engine shut-off switch when the engine
is not running.
EJU31180Start switch
Push the start switch (green button) to start
the engine.
NOTE:
The engine will not start when the clip is re-
moved from the engine shut-off switch or if the
throttle lever is squeezed.
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.

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 pilot outlets. If water is not being dis-
charged from the outlets, cooling water may
not be circulating in the engine. When this oc-
curs, stop the engine and check for the cause.
(See pages 29 and 76 for more information.)
NOTE:
If the cooling water passages are dry, it will
take about 20 seconds for the water to reach
the outlets after the engine is started.
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 determines
the speed and degree of a turn, throttle must
always be applied when attempting a turn, ex-
cept at trolling speed.
This model is equipped with the Yamaha En-
gine Management System (YEMS) that in-
cludes an off-throttle steering (OTS) system.
It will activate at planing speeds should you
attempt to steer the watercraft after releasing
the throttle lever. The OTS system assists in
turning by continuing to supply some thrust
while the watercraft is decelerating, but you
can turn more sharply if you apply throttle
while turning the handlebars.
The OTS system does not function below
planing speeds or when the engine is off.
Once the engine slows down, the watercraft
will no longer turn in response to handlebar in-

at the cooling water pilot outlet while the en-
gine is running. If there is no discharge of wa-
ter, 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
engine shut-off switch. Severe injury ordeath could result from coming in contact
with the rotating parts of the jet pump.
CAUTION:
ECJ00800
This watercraft is equipped with a catalytic
converter.

If the “WARNING” light, engine overheat
warning indicator, and buzzer come on,
reduce the engine speed and return to
shore. If you ignore these signals, the
engine will stop running and cannot be
restarted until the exhaust system cools
down.

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 en-
gine damage.
If the overheat warning is ignored, engine and
exhaust system heat may increase, particu-
larly if the watercraft is operated at higher

speeds. If this occurs, the “WARNING” light
and the engine overheat warning indicator
come on and the buzzer sounds continuously.
In addition, the warning system will cut the ig-
nition to the engine to reduce the risk of se-
vere overheating. The engine cannot be
started until it cools down, so it may be neces-
sary to have the watercraft towed back to the
shore. (See “Towing the watercraft” on page
78 for towing procedures.)
The warning signals will be cleared when the
engine is restarted after it has cooled down.
NOTE:
If multiple warnings occur at the same time,
their priority is as follows:
(1) Final engine overheat warning
(2) Fuel level warning
(3) Oil level warning
(4) Initial engine overheat warning
(5) Exhaust temperature warning
(6) Check engine warning
EJU31610Exhaust temperature warning indicator
This model is equipped with an exhaust tem-
perature warning system.
If the exhaust temperature becomes too hot,
the “WARNING” light and the exhaust tem-
perature warning indicator begin to blink, and
the buzzer sounds intermittently.If this occurs, reduce the engine speed and
return to shore to allow the exhaust system to
cool down.
WARNING
EWJ00830
Do not touch the hot muffler or catalytic
converter during or immediately after en-
gine operation; they can cause serious
burns. In addition, the catalytic converter
becomes hotter after the engine stops be-
fore cooling down.
CAUTION:
ECJ00810
This model is equipped with a catalytic
converter.

If the “WARNING” light, exhaust temper-
ature warning indicator, and buzzer
come on, reduce the engine speed (be-
low 4000 r/min) and return to shore.

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 en-
gine damage.
The warning signals will be cleared when the
engine is restarted after it has cooled down.

tected, the “WARNING” light and the check

Pre-operation checks EJU31990Pre-operation check list
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
EWJ00410
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 each time the watercraft is used. These checks can be
completed in a short time. It is worth the time spent to ensure safety and reliability.
