Watercraft operation modes
EJU36787Low RPM Mode
The Low RPM Mode is a function that limits
the maximum engine speed to approximately
70% of the maximum engine speed in the
normal mode.
The Low RPM Mode can only be activated
and deactivated by operating the remote
control transmitter that is included with this
watercraft. (See page 25 for information on
the remote control transmitter.)
TIP:
The Low RPM Mode can only be activated
when the engine is stopped in the unlock
mode of the Yamaha Security System.
Activating and deactivating the Low RPM
Mode
Activation of the Low RPM Mode will be con-
firmed by the number of beeps when the re-
mote control transmitter is operated, and by
the “L-MODE” indicator light of the multifunc-
tion information center. (See page 39 for in-
formation on the multifunction information
center.)
TIP:
If the remote control transmitter is operated
while the multifunction information center is
in the standby state, the center performs the
initial operation, and then the setting is se-
lected.
To activate the Low RPM Mode:
Push the “L-Mode” (unlock) button on the re-
mote control transmitter for more than 4 sec-
onds. Once the beeper sounds three times
and the “UNLOCK” indicator light blinks
three times, then comes on, the “L-MODE”
indicator light comes on and the Low RPM
Mode is activated.
TIP:
If the Low RPM Mode is activated immediate-
ly after the information display turns off, the
“L-MODE” indicator light will not come on.
The “L-MODE” indicator light will come on
when the engine is started.1Remote control transmitter
