Do not attempt to modify this watercraft!
Modifications to your watercraft may
reduce safety and reliability, and render
the watercraft unsafe or illegal for use.

Attach the engine shut-off cord (lanyard)
to wrist and keep it free from the handle-
bars so that the engine stops if the opera-
tor falls off. After riding, remove the
engine shut-off cord from the watercraft to
avoid accidental starting or unauthorized
use by children or others.

Scan carefully for swimmers and stay
away from swimming areas. Swimmers
are hard to see and you could acciden-
tally hit someone in the water.

Avoid being hit by another boat! You
should always take the responsibility to
watch for traffic; other boaters may not be
watching for you. If they do not see you,
or you maneuver more quickly than other
boaters expect, you risk a collision.

Maintain a safe distance from other boats
or watercraft, and also watch for boats’ ski
ropes or fishing lines. Obey the “Safe
boating rules” and be sure to check
behind you before making a turn. (See
Safe boating rules on page 1-16.)
EJU13820
Recommended equipment
The following items should be carried on
board your watercraft:

Sound-signaling device
You should carry a whistle or other sound-
signaling device that can be used to sig-
nal other boats.

Visual distress signals
It is recommended that an authority-
approved pyrotechnic device be stored in
a waterproof container on your watercraft.
A mirror can also be used as an emer-
gency signal. Contact your Yamaha
dealer for more information.

Watch
A watch is helpful so you will know how
long you have been operating.

Towline
A towline can be used to tow a disabled
watercraft in an emergency.

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 colorless, 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 engine on land until everyone
is away from stern. Hot water and steam
spurting from exhaust outlet can cause
serious burns.

Hot muffler surfaces can cause serious
burns. Do not touch any muffler surface
during or after engine operation. Catalytic
converter gets hotter after engine stops.

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 has the Yamaha
Engine Management System (YEMS)
that includes 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
input until you apply throttle again or you
reach trolling speed. Practice turning in
an open area without obstructions 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 pro-
duce some movement whenever the
engine is running. There is no “neutral”
position.

Keep away from the intake grate 1 while
the 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.

Never insert any object into the jet thrust
nozzle 2 while the engine is running.
Severe injury or death could result from
coming in contact with the rotating parts
of the jet pump.

Stop the engine and remove the clip 3
from the engine shut-off switch 4 before
removing any debris or weeds, which may
have collected around the jet intake.
