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.

Watercraft control functionsEJU45090Yamaha 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 using the
engine lock screen of the multifunction infor-
mation center. The engine cannot be started
if the lock mode of the security system is se-
lected. The engine can only be started if the
unlock mode is selected.
TIP:
The Yamaha Security System setting can
only be selected while the engine is stopped.
EJU45100Yamaha Security System setting
The Yamaha Security System setting can be
confirmed by the lock or unlock mode indica-
tor on the multifunction information center.
To select the lock or unlock mode of the
Yamaha Security System:
(1) Stop the engine.
TIP:
If the multifunction information center is
turned off because the engine is stopped,
perform one of the following operations to
turn on the center without starting the engine.
Push the start switch briefly.
While pushing the engine stop switch,
push the start switch.(2) Tap the lock or unlock mode indicator on
the multifunction information center.
(3) Flick up or down to set each digit of the
4-digit PIN, and then tap the “Enter” but-
ton.
TIP:
The default setting for the PIN is “1234”. The
PIN can also be changed. (See page 43 for in-
formation on changing the PIN.)
(4) Tap “ON” to select the lock mode of the
Yamaha Security System or tap “OFF” to
select the unlock mode, and then tap
“Save”.
(5) The beeper sounds once when the lock
mode of the Yamaha Security System is
selected and two times when the unlock
mode is selected, and the multifunction
information center returns to the home
screen.

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 24 for
Yamaha Security System setting proce-
dures.)
Clip is removed from the engine shut-off
switch.
Throttle lever is squeezed.
Throttle lever is malfunctioning.
RiDE lever is squeezed.
RiDE lever is malfunctioning.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.
EJU43342RiDE lever
When the RiDE lever is squeezed, the reverse
gate lowers and the watercraft starts moving
in reverse. If the watercraft is moving forward,
the watercraft gradually slows down until it
stops, and then the watercraft starts moving
in reverse.
When the RiDE lever is released, it automati-
cally returns to its fully closed (idle) position
and the reverse gate moves to the neutral po-
sition.

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.EJU31294Adjustable tilt steering system
The position of the handlebars can be adjust-
ed back and forth by operating the tilt lever.
To adjust the handlebar position:
(1) Pull the tilt lever up to disengage the han-
dlebar lock, and then move the handle-
bars back or forth to the desired position.
WARNING! Never pull the tilt lever dur-
ing operation, otherwise the handle-
bars may suddenly change position,
which may lead to an accident.

(2) Make sure that the tilt lever returns to its
original position and that the handlebars
are securely locked in place.
EJU35975Cooling water pilot outlet
When the engine is running, some of the
cooling water that is circulated in the engine
is discharged from the cooling water pilot
outlet.
There is a cooling water pilot outlet on the
port (left) side of the watercraft. To check for
proper operation of the cooling system, make
sure that water is being discharged from the
cooling water pilot outlet. If water is not being
discharged from the outlet, stop the engine
and check the jet intake for clogging. (See
page 99 for information on the jet intake.)
TIP:
It will take about 60 seconds for the water
to reach the outlet 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 the
water 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.1Cooling water pilot outlet
