Specifications

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 necessary 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 en-
gine 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 ac-
complished 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 temporarily dis-
engaged by engaging in the black button in the side of the
throttle handle. This allows the engine to increase RPM in neu-

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 with 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 decreases 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. Teh 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 teh 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 shoulddisplay
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 teh +/- switch will increase or decrease the Set Point by 20 RPM. Holding the switchincreases 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.
