Engine overheat warning
system
This model is equipped with an engine
overheat warning system.
If the engine starts to overheat, the warn-
ing light and the engine overheat warning
indicator begin to blink, the buzzer sounds,
and the engine speed will be limited to about
3,400 r/min.
When this occurs, check for water dis-
charge at the cooling water pilot outlet. If
there is no discharge of water, reduce the
engine speed and beach the watercraft, and
then check the intake grate and impeller for
clogging.
WARNING@ Before attempting to remove weeds or
debris from the intake grate or impeller,
shut the engine off and remove the clip
from the engine shut-off switch. Severe
injury or death could result from coming
in contact with the rotating parts of the
jet pump.
@
CAUTION:@ 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
engine damage.
@
NOTE:@ Press the reset button on the multifunction
information center to stop the buzzer.

5. While lightly squeezing the throttle lever,
push the start switch (green button).
WARNING@ On this watercraft, the engine is con-
nected directly to the jet pump. Starting
the engine immediately generates some
thrust. Apply only enough throttle to
keep the engine running.

engine starts to run.
CAUTION:@
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

motor may be damaged. If the engine
does not start in 5 seconds, release
the start switch, wait 15 seconds, and
try again.
@

Operating your watercraft
EJU01069
Getting to know your
watercraft
Operating your watercraft requires skills
acquired through practice over a period of
time. Take the time to learn the basic tech-
niques well before attempting more difficult
maneuvers.
Operating your new watercraft can be a
very enjoyable activity, providing you with
hours of pleasure. However, it is essential to
familiarize yourself with the operation of the
watercraft to achieve the skill level neces-
sary to enjoy riding safely. Before operating
this watercraft, read this Owner’s/Operator’s
Manual, the Riding Practice Guide, and all
warning and caution labels on the water-
craft. Pay particular attention to the safety
information on pages 1-10 to 1-16. These
materials should give you an understanding
of the watercraft and its operation.
Remember: This watercraft is designed to
carry the operator and one passenger.
Never exceed the maximum load limit or
allow more than 2 persons to ride the water-
craft at one time.
EJU01070
Learning to operate your
watercraft
Before operating the watercraft, always
perform the pre-operation checks listed on
page 3-5. The short time spent checking the
watercraft will reward you with added safety
and reliability.
Check all local laws before operating your
watercraft.
Operate defensively at safe speeds and
keep a safe distance away from people,
objects, and other watercraft. Select a wide
area to learn in, where you have good visi-
bility and light boat traffic.
Use the buddy system—operate with
someone nearby. Scan constantly for peo-
ple, objects, and other watercraft. Be alert
for conditions that limit your visibility or block
your vision of others.
Attach the engine shut-off cord (lanyard)
to your wrist and keep it free from the han-
dlebars so that the engine stops if the opera-
tor falls off.
Wear a personal flotation device (PFD).
All riders must wear an authority-approved
PFD that is suitable for personal watercraft
use. Maximum load: 160 kg (353 lb)
Load is the total weight of cargo, opera-
tor and passenger.
