EJU45891Reverse assist
The reverse assist is a function for temporar-
ily increasing the engine speed when moving
in reverse, such as to enter the water
smoothly when launching the watercraft from
a trailer.
This function operates after the engine is
started and only if the watercraft is not shifted
into forward.
TIP:
Once the watercraft is shifted into forward af-
ter the engine is started, the reverse assist
cannot be operated.

assist
The activation of the reverse assist can be
confirmed by the reverse assist indicator on
the multifunction information center.
To activate the reverse assist:

Squeeze the throttle lever.EJU46280T.D.E. (thrust directional enhancer)
The T.D.E. is a function for slightly lifting or
lowering the reverse gate from the neutral po-
sition to operate the watercraft at very low speeds when the engine is running at idling
speed.
This function can be used only when the wa-
tercraft is in neutral.
Activating and deactivating the T.D.E.
The activation of the T.D.E. can be confirmed
by the T.D.E. indicator on the multifunction
information center.

gine is stopped.
EJU46420No-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 when the wa-
tercraft is in neutral, or when the watercraft is
shifted into forward and the engine is operat-
ing at idling speed.
TIP:
If the no-wake mode is activated when the
watercraft is in neutral, the watercraft will au-
tomatically shift into forward and the water-
craft will start moving at a low speed.Activating and deactivating the no-wake
mode
The activation of the no-wake mode can be
confirmed by the no-wake mode indicator on
the multifunction information center.
To activate the no-wake mode:
(1) Shift into neutral, or release the throttle
lever and let the engine speed return to
idle.

ting the maximum watercraft speed.
The maximum watercraft speed can be se-
lected from two settings.

trol mode:
(1) Release the throttle lever and let the en-gine speed return to idle.
(2) Activate each drive control mode.
(3) Squeeze the throttle lever.
Selecting the drive control mode settings
The drive control mode setting for the maxi-
mum watercraft speed is saved. In addition,
the activation and settings of the drive control
mode can be locked to prevent others from
changing them. When the drive control mode is locked, a PIN
must be entered to operate the drive control
mode screen.
To select the maximum watercraft speed set-
ting:
(1) Select “Speed”.
(2) Select the maximum watercraft speed
setting.

EJU46390Cruise assist
The cruise assist is a function for maintaining
a desired engine speed within a fixed range
while operating the watercraft. Once the
cruise assist is activated, the set engine
speed can be increased or decreased. How-
ever, the adjustment is limited to a maximum
of five increments above or below the initial
cruise assist setting.
TIP:
The cruise assist can only be set between en-
gine speeds of approximately 4000 r/min and
approximately 7000 r/min.
Activating and deactivating the cruise as-
sist
Activation of the cruise assist can be con-
firmed by the cruise assist indicator on the
multifunction information center.
To activate the cruise assist:
(1) Operate the throttle lever until the de- sired engine speed is reached.
(2) When the engine speed reaches the de- sired cruise assist setting, push the “CRUISE/NO WAKE” switch. Once the
beeper sounds three times and the
cruise assist indicator is displayed, the
cruise assist is activated.
(3) When the cruise assist is activated, slow- ly squeeze the throttle lever to keep it
squeezed further than the position at
which the cruise assist was set.
TIP:
Check the multifunction information center to
make sure that the cruise assist is activated
before squeezing the throttle lever to the full
throttle position. If the cruise assist is not ac-
tivated, the engine will respond normally to
the throttle operation.
(4) Once the cruise assist is activated, pushthe upper side of the “SPEED ADJUST”
switch to increase the set engine speed
or the lower side of the “SPEED AD-
JUST” switch to decrease the set engine
speed. The engine speed can be

TIP:
Because the cruise assist can only be set be-
tween engine speeds of approximately 4000
r/min and approximately 7000 r/min, the
cruise assist level cannot be adjusted to an
engine speed outside of this range.
To deactivate the cruise assist:
Relax your grip on the throttle lever past the
position at which the cruise assist was set.
The beeper sounds two times and the cruise
assist indicator disappears when the cruise
