To drain water from the water separator:
(1) Place a drain pan or dry cloth under thewater separator.
(2) Gradually loosen the drain screw to drain the water. Catch the draining water in the
drain pan or soak it up with the dry cloth
so that it does not spill into the engine
compartment. If any water spills into the
watercraft, be sure to wipe it up with a
dry cloth.
(3) Securely tighten the drain screw until it stops.

Make sure that there are no obstacles or
people behind you before shifting into
reverse.
Do not touch the reverse gate while the
RiDE lever is being operated, otherwise
you could be pinched.
If the RiDE lever and throttle lever are
being operated at the same time, do not
release only the RiDE lever. Otherwise,
the watercraft could accelerate more
quickly than expected, which may lead
to an accident.
The RiDE lever and throttle lever can be oper-
ated to change the forward or rearward
movement of the watercraft only when the
engine is running. When the RiDE lever is
squeezed, the reverse gate lowers and de-
flects the water jet being discharged from the
jet thrust nozzle so that the watercraft moves
in reverse or is in neutral. When the throttle le-
ver is squeezed, the reverse gate rises and
the watercraft moves forward.
TIP
This model is equipped with a function
which limits the engine speed in reverse.
When the engine is started, the reverse
gate automatically moves to the neutral po-
sition.
To shift into reverse:
(1) Release the throttle lever.
(2) Squeeze the RiDE lever. The reversegate will lower, the engine speed will in-
crease, the watercraft will start moving in reverse, and the “R” (reverse) shift indi-
cator will be displayed.To shift into neutral from reverse:
Release the RiDE lever. The reverse gate will
automatically return to the neutral position

and the “N” (neutral) shift indicator will be dis-
played.
TIP
Although the neutral position helps keep the
watercraft from moving even when the en-
gine is running, some movement may occur.
To shift into forward:
(1) Release the RiDE lever.
(2) Squeeze the throttle lever. The reversegate will rise completely, the engine
speed will increase, the watercraft will
start moving forward, and the “F” (for-
ward) shift indicator will be displayed.

Watercraft operation modes
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.
Activating and deactivating the reverse
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:
(1) Start the engine.
(2) Squeeze the RiDE lever to the fully openposition, and then push the upper side of
the “SPEED ADJUST” switch. Once the
beeper sounds three times and the re-
verse assist indicator is displayed, the engine speed will increase. The engine
speed can be adjusted to two levels: +1
and +2.
To deactivate the reverse assist:
Perform one of the following operations. The
beeper sounds two times and the reverse as-
sist indicator disappears when the reverse
assist is deactivated.
Relax your grip on the RiDE lever.
Push the lower side of the “SPEED AD-
JUST” switch when the reverse assist level
is set to +1.
Squeeze the throttle lever.EJU45900T.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.
TIP
While the watercraft is shifted into forward,
the “TRIM/T.D.E.” switch controls the electric
trim system. (See page 31 for information on
the electric trim system.)
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.
To activate the T.D.E.:
(1) Shift into neutral.
(2) Push the upper side of the “TRIM/T.D.E.”switch to move forward at a very low
speed or push the lower side of the
“TRIM/T.D.E.” switch to move in reverse
at a very low speed.
TIP
While the T.D.E. is activated, the “N” (neutral)
shift indicator will be displayed and “0” will be
displayed on the speedometer.
To deactivate the T.D.E.:
Perform one of the following operations. The
T.D.E. indicator disappears and the T.D.E. is
deactivated.
Squeeze the throttle lever.
Squeeze the RiDE lever.
Push and hold the “CRUISE/NO WAKE”
switch.
While moving forward at a very low speed,
push the lower side of the “TRIM/T.D.E.”
switch.
While moving in reverse at a very low
speed, push the upper side of the
“TRIM/T.D.E.” switch.
TIP
The T.D.E. is also deactivated when the en-
gine is stopped.
EJU45910No-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. While
the watercraft is operating in no-wake mode,

gine speed each above and below the initial
engine speed.
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 throttlelever and let the engine speed return to
idle.
(2) Push and hold the “CRUISE/NO WAKE” switch. Once the beeper sounds three
times and the no-wake mode indicator is
displayed, the no-wake mode is activat-
ed. (3) Push the upper side or the lower side of
the “SPEED ADJUST” switch to adjust
the engine speed to three settings: “No
Wake –1”, “No Wake” (standard setting),
and “No Wake +1”.
To deactivate the no-wake mode:
Perform one of the following operations. The
beeper sounds two times and the no-wake
mode indicator disappears when the no-
wake mode is deactivated.
Push the “CRUISE/NO WAKE” switch.
Squeeze the throttle lever.
Squeeze the RiDE lever.
TIP
The no-wake mode is also deactivated when
the engine is stopped.

EJU45930Cruise 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 3000 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

(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
changed in the range of the cruise assist
levels –5 to +5.
TIP
Because the cruise assist can only be set be-
tween engine speeds of approximately 3000
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
assist is deactivated.
