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

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

(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.
