Specifications

Firmly push the red button until the breaker re-sets.
There will be an audible click. Try again to start the engine.
If the breaker trips again, the engine requires attention.
Take your boat immediately to your dealer.
In addition to the 50A circuit breaker, the engines are
also equipped with additional component overload protec-
tion, including a 15A ATO fuse for the fuel pump, a 15A ATO
fuse for the injectors and a 15A ATO fuse for the ECM unit.
If you suspect that any of these fuses may not be
operating as designed, you should take your boat to your
dealer for attention.
If during maintenance or inspection it becomes neces-
sary to remove or re-position any of the engine’s wiring or
wire harness(es) verify that the wiring has been returned to
its original position and that all harnesses are routed
correctly before attempting to use the boat again. If a wiring
clip or retainer breaks, replace it immediately. Wiring is
specifically routed to eliminate problems related to engine
heat and spray or immersion in liquids. Electrical problems
can result if wiring is moved from the original position!
SHIFT/TROTTLE CONTROL
A one-hand, single-lever control operates as both a
gear shifter and a throttle. The lever automatically locks in
the neutral position (straight up and down) for safety. The
lever can be moved from neutral only by raising the lifter
under the ball knob. Shifting is accomplished by moving the
lever into the first 45 degrees of travel.
Moving the lever forward engages the running gear;
moving it back from center puts the drive train into reverse.
By advancing the lever beyond 45 degrees you move from
the shifting range to the throttle range.
Never attempt to shift without the engine running!
The shift mechanism of this control can be tempo-
rarily disengaged by engaging in the black button in the
side of the throttle handle. This allows the engine to
increase RPM in neutral during warm-up.
OPTIONAL CRUISE CONTROL SYSTEM
On boats equipped with a Cruise Control System, it is
possible to review various functions by toggling to the cruise
control read-outs on the multi-function gauge explained
earlier in this section. Note also that the throttle position
must always be greater than the speed set on the cruise
control. For example, if the cruise was set at 35 mph but
the throttle position is equivalent to 25 mph, the boat will
not reach 35. This is also true of the RPMs. Also, the cruise
control cannot be engaged when the boat is at idle speed.
System Start-Up: When the ignition is turned on the
cruise control system starts in OFF mode. While it is in OFF
mode, the LCD display will show the current time.
RPM Set-Point Adjustment: In order to adjust the RPM
Set Point in OFF Mode, first move the RPM/SPEED mode
selection switch to the RPM position. Using the +/- switch,
select the desired Set Point. The RPM icon will illuminate
and the LCD will display the current Set Point. Briefly
pressing the +/- switch will increase or decrease the Set
Point by 20 RPM. Holding the switch will increase or
decrease by 100 RPM. The RPM Set Point is limited to a
minimum of 1200 RPM and a maximum of 5000 RPM.
Speed Set Point Adjustment: In order to adjust the
Speed Set Point in OFF Mode, first move the RPM/SPEED
Mode selection switch to the SPEED position. Use the +/-
switch to select the desired Set Point. The SPEED icon will
illuminate and the LCD will display the current Set Point. Brief
presses of the +/- switch will increase or decrease the Set
Point by 0.2 MPH. Holding the switch increases or de-
creases the Set Point by 1.0 MPH. The Speed Set Point is
limited to a minimum of 5.0 MPH and a maximum of 50
MPH.
Turning On RPM Cruise Control Mode: To turn on the
Cruise Control System in RPM Control mode, make sure
that the RPM/SPEED mode selection switch is in the RPM
position and that current engine speed is at least 400 RPM
less than the Set Point. Press and hold the ON/OFF switch
in the ON position for approximately one second. The LCD
should now display the current engine speed, the RPM icon
should be illuminated and the LOCK icon should be blinking.
Turning On Speed Cruise Control Mode: To turn on the
Cruise Control in Speed Control mode, make sure that the
RPM/SPEED mode selection is at least 3.0 MPH less than
the Set Point. Press and hold the ON/OFF switch in the ON
position for approximately one second. The LCD should now
display the current vessel speed, the SPEED icon should be
illuminated and the LOCK icon should be blinking.
Turning On Manual Cruise Control Mode: To turn on
the Cruise Control in Manual Control mode, make sure that
the RPM/SPEED mode selection switch is in the MANUAL
(center) position and that current engine speed is at least
1200 RPM. Then press and hold the ON/OFF switch in the
ON position for approximately one second. The LCD should
display the current engine speed and the LOCK icon should
be blinking.
Manual Set Point Adjustment: The Manual Set Point
can be adjusted using the +/- switch. The LOCK icon will
disappear and the LCD will display the current Set Point.
Short presses of the +/- switch will increase or decrease
the Set Point by 20 RPM. Holding the switch increases or
decreases the Set Point by 100 RPM. The Manual Set
Point is limited to a minimum of 1200 RPM and a maximum
of 5000 RPM.
Using Speed Control Mode: Manual Control works
basically in the same way that RPM Control Mode does.
The difference is that when the system is turned ON in
manual mode the Set Point is set to the current engine
speed. For example, if the Cruise Control is OFF and the
engine speed is 2500 RPM, and the system is turned on,
the engine will hold the engine speed at 2500 RPM.
Disengaging the Cruise Control System: There are two
ways to disengage the system: Pulling back the throttle will
disengage the system at any time. The system remains ON
and can be engaged by accelerating the boat until the
LOCK icon stays illuminated. Or by moving the ON/OFF
switch to OFF. It is recommended that the throttle be pulled
back before turning off the system.
