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

tor light goes off and the Low RPM Mode is
deactivated. When the Low RPM Mode is de-
activated, the watercraft returns to the nor-
mal operation mode.
EJU42484No-wake mode
The no-wake mode is a function that main-
tains the engine speed at a fixed setting for
operating the watercraft at low speeds. This
function can be used only for forward water-
craft operation or when the watercraft is in
neutral.
TIP:
The no-wake mode can only be activated
after 5 seconds have elapsed since starting
the engine.
If the no-wake mode is activated when the
watercraft is operating in neutral, the re-
verse gate will move to the forward posi-
tion.
Activating and deactivating the no-wake
mode
Activation of the no-wake mode will be con-
firmed by the number of beeps when the
“NO-WAKE MODE” switch is pushed, and by
the digital speedometer display of the multi-
function information center. (See page 39 for
information on the multifunction information
center.)
TIP:
The beeps and the blinking digital speedom-
eter display also indicate the activation of the
cruise assist. (See page 37 for information on
the cruise assist.)
To activate the no-wake mode:
(1) Release the throttle lever and let the en-
gine speed return to idle.
(2) Push and hold the “NO-WAKE MODE”
switch. Once the beeper sounds three
times quickly and “8” (when kilometers
