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 1-14.)
EJU01382
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
When transporting or storing your water-
craft, always place the fuel cock knob in
the “OFF” position, otherwise gasoline
may overflow from the carburetor.
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.
EJU01271
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. You may still have some turning
ability immediately after releasing the
throttle, but once the engine slows down,
the watercraft will no longer respond to
handlebar input until you apply throttle
again or you reach a trolling speed. Prac-
tice turning in an open area without
obstructions until you have a good feel for
this maneuver.
This watercraft are 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 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 in the jet thrust
nozzle 2. 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 that may
have collected around the jet intake.
Avoid forceful jet thrust and limited visibil-
ity while reboarding. Get to standing or
kneeling position quickly, but do not
expose yourself to forceful jet thrust.
EJU01005
Safe boating rules
Your Yamaha watercraft is legally consid-
ered a powerboat. Operation of the water-
craft must be in accordance with the rules
and regulations governing the waterway on
which it is used.
