Hour meter/Voltmeter 
NOTE:@ To switch the display between the hour
meter and voltmeter, push the select
button1 for at least 1 second after the
meter is displayed for more than 10 sec-
onds. 
@
Hour meter 
The hour meter is provided to make it
easy to follow the maintenance schedule. 
The meter shows the hours of engine
operation that have elapsed since the water-
craft was new.
Vo l t m e t e r  
The voltmeter is provided to display the
voltage of the battery. 
When the battery voltage is normal, the
voltmeter displays approximately 12 volts. 
If the battery voltage is less than 8.0 volts,
“LO” is displayed on the voltmeter and if the
voltage is above 18.1 volts, “HI” is displayed
on the voltmeter. If “HI” or “LO” is displayed,
beach the watercraft and, if necessary, have
a Yamaha dealer check the charging system
and the battery. 
EJU20760 
Check engine warning indicator 
If a sensor malfunction or a short circuit is
detected, the warning light and the check
engine warning indicator begin to blink and
the buzzer sounds intermittently. 
If this occurs, reduce the engine speed,
beach the watercraft, and have a Yamaha
dealer check the engine.

EJU20770 
Fuel warning indicator 
If the fuel remaining in the tank drops to
about 13 L (3.4 US gal, 2.9 Imp gal), the
lowest two fuel level segments, the fuel
warning indicator, and the warning light all
begin to blink. The buzzer also starts sound-
ing intermittently. 
The warning signals will be cleared when
the engine is restarted after refilling. 
EJU20782 
Oil pressure warning indicator 
If the oil pressure does not rise to specifi-
cation, the warning light and the oil pressure
warning indicator begin to blink and the
buzzer sounds intermittently. At the same
time, the engine speed is limited to help pre-
vent damage. 
If this occurs, reduce the engine speed,
beach the watercraft, and then check the
engine oil level. (See page 3-7 for engine oil
level checking procedures.) If the oil level is
low, add enough engine oil to raise it to the
proper level. If the oil level is sufficient, have
a Yamaha dealer check the watercraft.
NOTE:@ Press the select button 1 on the multifunc-
tion meter to stop the buzzer.

EJU21182 
Engine overheat warning indicator 
This model is equipped with an engine
overheat warning system. 
If the engine starts to overheat, the warn-
ing light and the overheat warning indicator
blink, and then come on. The buzzer also
begins to sound intermittently, and then it
sounds continuously. After the light and indi-
cator start to blink and the buzzer sounds,
the engine speed is limited to help prevent
damage. 
If this occurs, immediately reduce the
engine speed, beach the watercraft, and
then check for water discharge at the port
(left) cooling water pilot outlet. If there is no
discharge of water, 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 select button 1 on the multifunc-
tion meter to stop the buzzer.

Operating your watercraft  
EJU12500 
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 1-11 to 1-19. These
materials should give you an understanding
of the watercraft and its operation. 
Remember: This watercraft is designed to
carry the operator and up to 2 passengers.
Never exceed the maximum load limit or
allow more than 3 persons (or 2 persons if a
water-skier is being pulled) to ride the water-
craft at one time. 
EJU10700 
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: 240 kg (530 lb) 
Load is the total weight of cargo, 
operator and passengers.
