Watercraft glossary
Trolling speed
“Trolling” is the lowest maneuvering speed. You are applying little or no throttle. The water-
craft is down in the water, and there is no wake.
Sub-planing speed
“Sub-planing” is a medium speed. The bow of the watercraft is slightly up from the water sur-
face, but you are still traveling through the water. There is a wake.
Planing speed
“Planing” is a faster speed. The watercraft is more level and is skimming on top of the water.
There is a wake.
Bow
The front end of the watercraft.
Stern
The rear end of the watercraft.
Starboard
The right side of the watercraft when facing forward.
Port
The left side of the watercraft when facing forward.
Bilge water
Water that has collected in the engine compartment.
Yamaha Engine Management System (YEMS) YEMS is an integrated, computerized management system that controls and adjusts ignition
timing, fuel injection, engine diagnostics, and the off-throttle steering (OTS) system.

EJU31385Yamaha Security System
The Yamaha Security System functions to
help prevent unauthorized use or theft of the
watercraft. The lock and unlock modes of the
security system can be selected by operating
the remote control transmitter that is included
with this watercraft. The engine cannot be
started if the lock mode of the security sys-
tem is selected. The engine can only be start-
ed if the unlock mode is selected. (See page
26 for information on the remote control
transmitter.)
TIP:
The Yamaha Security System settings can
only be selected while the engine is stopped.
EJU37413Yamaha Security System settingsThe Yamaha Security System settings will be
confirmed by the number of beeps when the
remote control transmitter is operated, and
by the “UNLOCK” indicator light of the dual
analog meter unit. (See page 36 for informa-
tion on the dual analog meter unit.)
TIP:
The beeper sounds two times for the nor-
mal operation mode or three times for the
Low RPM Mode. (See page 34 for Low
RPM Mode activation procedures.)
If the remote control transmitter is operated
while the dual analog meter unit is in the
standby state, the unit will perform the ini- tial operation, and then the setting is se-
lected.
To select the lock mode:
Push the lock button on the remote control
transmitter briefly. The beeper sounds once
and the “UNLOCK” indicator light blinks
once, then goes off. This indicates the lock
mode is selected.
To select the unlock mode:
Push the “L-Mode” (unlock) button on the re-
mote control transmitter briefly. The beeper
sounds two or three times and the “UN-
LOCK” indicator light blinks two or three
times, then comes on. This indicates the un-
lock mode is selected.

EJU31153Engine stop switch “ ”
The engine stop switch (red button) stops the
engine when the switch is pushed.
EJU31164Engine shut-off switch “ ”
The engine shut-off switch automatically
stops the engine when the clip, on the end of
the engine shut-off cord (lanyard), is removed
from the switch, such as if the operator falls
off the watercraft.
Insert the clip under the engine shut-off
switch before starting the engine.
When the engine is not running, remove the
clip from the engine shut-off switch to pre-vent accidental starting or unauthorized op-
eration by children or others.

NOTICE
ECJ01311
Do not run the engine over 4000 r/min on
land. Also, do not run the engine for more
than 15 seconds without supplying water,
otherwise the engine could overheat.
The start switch (green button) starts the en-
gine when the switch is pushed.
Release the start switch as soon as the en-
gine starts to run. If the engine does not start
in 5 seconds, release the start switch, wait 15
seconds, and then try again.
NOTICE: Never
push the start switch while the engine is
running. Do not operate the start switch
for more than 5 seconds, otherwise the
battery will be discharged and the engine

will not start. Also, the starter motor could
be damaged.
[ECJ01041]
The engine will not start under any of the fol-
lowing conditions:
Lock mode of the Yamaha Security System
has been selected. (See page 27 for
Yamaha Security System setting proce- dures.)
Clip is removed from the engine shut-off
switch.
Throttle lever is squeezed.EJU31212Throttle lever
The throttle lever increases the engine speed
when the lever is squeezed.
The throttle lever returns automatically to its
fully closed (idle) position when released.
EJU31262Steering system
By turning the handlebars in the direction you
wish to travel, the angle of the jet thrust noz-
zle is changed, and the direction of the water-
craft 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,
except 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 sys-
tem 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.
EJU37342Telescopic steering system
The position of the handlebars can be adjust-
ed up or down by operating the lock lever.
The handlebars can be adjusted to three po-
sitions.
To adjust the handlebar position:
(1) Pull the lock lever up to disengage thehandlebar lock, and then move the han-
dlebars up or down to the desired posi-
tion. WARNING! Never pull the lock
lever during operation, otherwise the
handlebars may suddenly change po-
sition, which may lead to an accident.
[EWJ01271]
(2) Make sure that the lock lever returns to its original position and that the handle-
bars are securely locked in place.
EJU41801Cooling water pilot outlets
When the engine is running, some of the
cooling water that is circulated in the engine
is discharged from the cooling water pilot
outlets.
There are cooling water pilot outlets on the
port (left) and starboard (right) sides of the
watercraft. To check for proper operation of
the cooling system, make sure that water is
being discharged from the port (left) pilot out-
let. If water is not being discharged from the
outlet, stop the engine and check the jet in-
take for clogging. (See page 94 for informa-
tion on the jet intake.)

TIP:
It will take about 60 seconds for the water
to reach the outlets after the engine is start-
ed.
Water discharge may not be constant
when the engine is running at idling speed.
If this occurs, apply a little throttle to make
sure that water discharges properly.
EJU40323Water separator
The water separator prevents water from en-
tering the fuel tank by collecting any water
that has entered the fuel tank breather hose if
the watercraft was capsized.
If water has collected in the water separator,
drain it by loosening the drain screw.
To drain water from the water separator:
(1) Place a drain pan or dry cloth under thewater separator. (2) Gradually loosen the drain screw to drain
the water. Catch the draining water in the
drain pan or soak it up with the dry cloth
so that it does not spill into the engine
compartment. If any water spills into the
watercraft, be sure to wipe it up with a
dry cloth.
(3) Securely tighten the drain screw until it stops.
