To switch to the tachometer from the speed-
ometer:
Push the “SPEED/RPM” button for at least 1
second after the multifunction information
center is activated. When the meter switches
to the analog tachometer function, the “RPM”
indicator light comes on.
Analog speedometer
The analog speedometer shows the water-
craft speed against water.
The small inner numbers on the meter show
the watercraft speed in kilometers per hour
“km/h” and the large outer numbers show the
speed in miles per hour “mph”.
The “SPEED” indicator light comes on when
the analog speedometer is selected.
To switch to the speedometer from the ta-
chometer:
Push the “SPEED/RPM” button for at least 1
second after the multifunction information

EJU42270Oil pressure warning
If the oil pressure drops significantly, the oil
pressure warning indicator and the “WARN-
ING” indicator light blink, and the buzzer
sounds intermittently. At the same time, the
engine speed is limited.
If the oil pressure warning is activated, imme-
diately reduce the engine speed, return toshore, and then check the engine oil level.
(See page 57 for information on checking the
engine oil level.) If the oil level is sufficient,
have a Yamaha dealer check the watercraft.

gine overheat warning indicator and the
“WARNING” indicator light stop blinking and
remain on, and the buzzer sounds continu-
ously. At the same time, the engine speed is
limited.
If the engine overheat warning is activated,
immediately reduce the engine speed, return
to shore, and then make sure that water is be-
ing discharged from the cooling water pilot
outlet while the engine is running. If there is no
discharge of water, stop the engine, and then
check the jet intake for clogging. (See page
99 for information on the jet intake.) NOTICE:
If you cannot locate and correct the cause
of the overheating, consult a Yamaha deal-
er. Continuing to operate at higher speeds

EJU40112Remote control transmitter check
Make sure that the remote control transmitter
operates properly. (See page 27 for Yamaha
Security System setting procedures and page
35 for Low RPM Mode activation procedures.)
EJU32663Engine shut-off cord (lanyard) check
Make sure that the engine shut-off cord (lan-
yard) is not damaged. If the cord is damaged,
replace it. WARNING! Never try to repair
the engine shut-off cord (lanyard) or tie it
together. The engine shut-off cord (lan-
yard) may not pull free when the operator
falls off, allowing the watercraft to contin-

EJU36345Starting the engine on water
WARNING
EWJ01530
Do not apply throttle when anyone is at the
rear of the watercraft. Turn the engine off
or keep it at idle. Water and debris exiting
the jet thrust nozzle can cause severe inju-
ry.
To start the engine:
(1) If the lock mode is selected for the
Yamaha Security System setting, select
the unlock mode. (See page 27 for
Yamaha Security System setting proce-
dures.)
(2) Move the watercraft to an area that is free
from weeds and debris, and has a water
depth of at least 60 cm (2 ft) from the bot-
tom of the watercraft. NOTICE: Never
run the engine in water that is less
than 60 cm (2 ft) deep from the bottom
of the watercraft, otherwise pebbles or
sand could be sucked into the jet in-
take, causing impeller damage and en-
gine overheating.

(3) Attach the engine shut-off cord (lanyard)
to your left wrist, and then attach the clip
to the engine shut-off switch. (See page
28 for information on operating the en-

limits the engine speed in neutral.
EJU42450Boarding the watercraft
WARNING
EWJ01111
Be sure the operator and any passengers
have practiced boarding from the water
while still close to shore before riding. A
person who has made many unsuccessful
attempts to get back on the watercraft may
become fatigued and suffer from expo-
sure, increasing the risk of injury and
drowning.
Board the watercraft in water free from weeds
and debris and at least 60 cm (2 ft) deep fromthe bottom of the watercraft. NOTICE: Never
run the engine in water that is less than 60
cm (2 ft) deep from the bottom of the wa-
tercraft, otherwise pebbles or sand could
be sucked into the jet intake, causing im-
peller damage and engine overheating.
