Watercraft control functionsEJU43690Remote control transmitter
The Yamaha Security System and Low RPM
Mode settings can be selected by operating
the remote control transmitter. (See page 26
for Yamaha Security System setting proce-
dures and page 35 for Low RPM Mode acti-
vation procedures.)
Since the watercraft is programmed to rec-
ognize the internal code from this transmitter
only, the settings can only be selected with
this transmitter.
If you accidentally lose your remote control
transmitter or if it is not operating properly,
contact a Yamaha dealer.
When operating the watercraft, always keep
the transmitter with you, such as by storing itin the transmitter holder in the glove compart-
ment, so that it is not lost.
NOTICE
ECJ00753
The remote control transmitter is not
completely waterproof. Do not sub-
merge the transmitter or operate it un-
derwater. If the transmitter is
submerged, dry it with a soft, dry cloth,
and then check that it is operating prop-
erly. If the transmitter is not operating
properly, contact a Yamaha dealer.
Keep the remote control transmitter
away from high temperatures and do
not place it in direct sunlight.
Do not drop the remote control trans-
mitter, subject it to strong shocks, or
place any heavy items on it.
Use a soft, dry cloth to clean the remote
control transmitter. Do not use deter-
gent, alcohol, or other chemicals.
Do not attempt to disassemble the re-
mote control transmitter yourself. Oth-
erwise, the transmitter may not operate
properly. If the transmitter needs a new
battery, contact a Yamaha dealer. Refer
to local hazardous waste regulations
when disposing of transmitter batteries.

warning is activated, the maximum 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
being 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 94 for information on the jet intake.)
NOTICE: 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 en-
gine damage.

Check engine warning
If a sensor malfunction or a short circuit is de-
tected, the check engine warning indicator
and the “WARNING” indicator light blink, and
the buzzer sounds intermittently for 30 sec-
onds.If the engine is stopped after the check en-
gine warning is activated, the information dis-
play will indicate an error code.
If the check engine warning is activated, im-
mediately reduce the engine speed, return to
shore, and have a Yamaha dealer check the
engine.
EJU43740Hour meter
The hour meter shows the total number of
hours that the engine has been running since
the watercraft was new.
TIP:
The elapsed time will be kept even if the bat-
tery terminals have been disconnected.
EJU43750Voltmeter
The voltmeter shows the battery voltage.
When the battery voltage is normal, the volt-
meter displays approximately 12 volts.

If the battery voltage has dropped significant-
ly, “LO” is displayed on the voltmeter. If the
battery voltage has risen significantly, “HI” is
displayed. If “LO” or “HI” is displayed, imme-
diately return to shore and have a Yamaha
dealer service the watercraft.
