Section 04 FUEL SYSTEM
Subsection 01 (INTELLIGENT THROTTLE CONTROL (iTC))
When throttle is applied, the engine will progres-
sively accelerate to an operating range whereby
full power eventually becomes available. If the en-
gine is throttled down sufficiently and for a long
enough period of time, engine power and acceler-
ation will again be reduced.
Sport Mode
Sport mode allows the operator for instant throttle
response.
Maximum engine power is available throughout
the engine operational range.
ECO Mode
When ECO mode is selected (fuel economy
mode), engine RPM is limited whereby an op-
timal cruising speed is maintained in order to
reduce fuel consumption.
Cruise Control
Cruise mode is a function of iTC (intelligent Throt-
tle Control) system that allows the operator to set
the desired maximum watercraft speed.
This is useful when cruising for long distances, op-
erating in limited speed zones, or towing a tuber,
skier or wake boarder.
Cruise mode only limits forward speed, the oper-
ator must keep the throttle depressed to maintain
forward speed.
Once the maximum cruise speed is set, the oper-
ator can vary the watercraft speed from idle speed
up to the set cruise speed using the throttle lever.
The set cruise speed will not be exceeded even if
the throttle lever is fully depressed.
As you proceed under a constant cruising speed
setting, keep your attention level up to maintain
good situational awareness.
Slowing down is a matter of releasing the throttle
lever further than the set point, or by pulling the
iBR lever in or decrease speed with the DOWN
button.
If the iBR lever is pulled in for braking, CRUISE
mode is overridden but not deactivated.
Once the iBR lever is released and the throttle is
pulled in to engage forward position, the cruise
function will reengage to limit the watercraft
speed as it was set before iBR lever activation.
Slow Speed Mode
The Intelligent Throttle Control also allows for a
Slow Speed Mode where the driver can adjust and
set idle speed. This is useful when operating in
slow speed zones where the driver must be es-
pecially attentive to possible obstacle avoidance.
The throttle plate will open a nd close as necessary
to maintain the set speed.
Ski Mode
Ski mode allows for repeated and precisely con-
trolled launches and a set towing speed, designed
specifically for towing a skier or wake boarder.
RAMP Function
The RAMP function available in ski mode is a pre-
programmed function used for launching and ac-
celerating the PWC when towing a skier or wake-
boarder.
TARGET SPEED Function
The TARGET SPEED function limits the maximum
towing speed.
Learning and Rental Keys
Learning and Rental keys limit the watercraft ma-
ximum speed. The full stroke of the throttle lever
is used while only a partial stroke of the throttle
plate is achieved. Therefore, greater throttle lever
movement is used while a smaller engine speed
and torque variation is applied through the throttle
actuator. This permits a more accurate and eas-
ier throttle operation to control the engine within
a specified torque curve and maximum speed set-
ting for a learner.
