Section 1 Initial System Start Up
The very first time your PerfectPass is turned on, it may ask you two questions:
1. [ 5.7L ^ = Yes ] If your boat has a standard 5.7 V8, press the UP key. If you
have an optional 6L or 8.1L, press the DOWN key.
2. [ Read in MPH ^ = Yes ] If you want your system to display in MPH, press the
Up Key. For metric, press the Down Key.
USING WAKEBOARDPRO
There are three operating modes to choose from: (1) Wakeboard Mode is speed based
and controls from the paddle wheel; (2) RPM Mode allows the user to set an RPM value;
and (3) Slalom Mode allows recreational slalom skiers to enter a speed for open water
skiing. (24 – 36 mph).
The ON/OFF key is pressed to turn control ON or OFF. System should always be in OFF
mode when not in use. Turning system ON or OFF is always done at neutral or at idle for
safety. You may be asked to confirm you are in neutral as follows [ IN NEUTRAL ^ =
Yes ].
Typically, wakeboarders prefer the pull characteristics of the speed based Wakeboard
Mode. This mode is designed for 9 – 25 mph. Open water skiers at higher speeds should
use the RPM or Slalom Mode.
Wakeboard Mode (Speed Based)
When system is ON, the screen will appear as above with set point speed at left. By using
Menu Key you can move around the screen and highlight set point to make speed
changes.

Once desired speed has been set, you can simply drive normally and when set point has
been reached or exceeded the system will engage and take over automatically. (You will
hear an audile beep and “WAKEBD” heading will become highlighted to confirm
engagement.
To disengage system, pull back on the throttle.
The key to good driving is to smoothly drive to engagement speed so PerfectPass can
seamlessly take control. If you have a heavily laden boat and need full throttle from start,
slowly pull back on handle as speed increases to help PerfectPass engage smoothly.
If the rider falls, pull throttle back and system will disengage. Return slowly to rider and
pull them back up. PerfectPass will once again engage when set speed is reached.
Menu Arrow – To move to another mode, use menu key to highlight Menu arrow and
press up key to confirm. The following screen will appear with other operating modes
you can select.
Adjustable Parameters KDW, NN – These background settings allow you to tailor the
pull characteristics of WakeboardPro. To access, highlight Menu Key , and press up to
highlight Wakeboard mode. When Wakeboard is highlighted, press Down Key and the
following screen will appear:
KDW (Throttle Pull Rate) – KDW can be changed using up or down keys. The higher
the value, the more aggressive the control. Heavy boats may need higher values. Factory
setting is about 80. Normal range is 80 – 200.
NN (Paddle wheel Filter Factor) – NN is set at about 120. The higher the value the
more filtering is done. If you feel you boat is surging a little too much, raise value by 20
or 30. If you feel the speed is slowly drifting around too much, try a lower value to
tighten control.
Speedometer Calibration – If you feel PerfectPass is not showing an accurate speed,
see calibration details on Page 7.

Section 2 RPM Mode
USING RPM MODE
In this mode, the screen will appear as follows:
Operating in this mode is very similar to using the Wakeboard or Trick modes, except the
system is now controlling to an RPM SETPOINT.
RPM DRIVING
Prior to towing the rider / skier, select the RPM SETPOINT by using the UP or DOWN
keys with the SETPOINT highlighted on the screen. Pull the rider up smoothly and
continue to accelerate up to or beyond the RPM SETPOINT so the system can engage
and take control. The digital tachometer should match the RPM set point.
Changes can be made to the RPM SETPOINT while the system in engaged (“on the fly”)
to fine-tune the RPM you desire.

Section 3 Slalom Mode (Requires Calibration)
SIMPLE SLALOM
This Simple mode is for recreational skiing and will provide an excellent, tournament
quality pull, however, it is not designed to be as accurate as the tournament class Slalom
modes.
This mode allows you to set speeds in 2 mph increments ranging from 24 – 36 mph. It is
designed for those wishing to use the system for open water skiing.
(Before calibrating Slalom Mode, you should calibrate at 20 mph in Wakeboard Mode - See Page 7).
Step 1 Calibrate RPM Baseline – Initial calibration of baselines should be done
with 2 – 3 people in boat and without a skier. If you set the speed at 34.0
mph, but your digital speed readout shows something different such as 33,
simply press the MENU key until the is highlighted then press the
DOWN key. This can be done on the fly or at the dock. Press the UP key
several times and the rpm baseline will increase 25 rpm per press. This
will increase the rpm on the boat which will increase the actual speed.
Adjust the rpm until the actual speed matches the SETPOINT. Press the
MENU key to highlight the then press the UP key to return to the main
Simple Slalom screen.
Baseline Calibration
Screen
If you are towing skiers, you can change the SETPOINT on the fly (i.e.
30 to 32), or you can raise the rpm baseline setting on the fly by going into
the BasCal Screen as described above. For example, you have 32 mph set,
but because you have five people in the boat, the speed may be running a
little slow due to the extra weight. You can adjust the speed by entering
the BseCal Screen and raising the rpm baseline until the digital
speedometer matches the desired speed.

Section 4 Using Name List
Additional PerfectPass features are accessed by pressing the MENU & UP keys together.
The features available vary depending on the make and model of your boat. If a feature
is not present on your PerfectPass then it is not available on your system. To move to the
next feature press the MENU key.
NAME LIST
This version of PerfectPass allows you to store up to eight names and their preferred
speed. The Name List can be accessed by pressing the UP key when the NAME/MODE
section is highlighted or by going into the SUBMENU and selecting the Name List.
Once in the Name List press the MENU key to move through the list. With the desired
name highlighted press the UP key to select the name from the list and load their settings
or press the DOWN key to edit the name.
Creating Names – First enter the Quick List. Press the MENU key until [NEW
ENTRY] is highlighted. Then press the UP key to enter a new name. The following
screen will then appear:
Scroll through the alphabet using UP & DOWN keys, and then press MENU to move to
next position. Press the MENU key to move through the settings. If you are
programming a JUMP or SLALOM name there will be another page of settings to enter.
Editing Names – As you scroll through list of names, instead of pressing UP key to
select that name, press the DOWN key to edit.
Note: Names can be changed by “Editing Names” but can only be deleted by performing
“System Reset”.

Section 5 Other Features
Press Menu & Up keys together to access the following:
Screen Contrast – By pressing up or down keys you can change the contrast level.
Range is 1 – 5. Lower values = better visibility in extreme sun. 3 is normal.
Name List – You can get to the name list through this feature, or by highlighting the
mode or name on main screen and press up.
System Info – This screen will display software version #, battery voltage, engine
selection, hour meter and water temperature. (Some information not on all boats)
Device Test – Troubleshooting information for servo motor or electronic throttle
systems.
-------------------------------------------------
More Throttle – If you see the # sign flashing in the upper right part of screen, this
means the system is running out of manual throttle. Advance the handle forward a little
until the # sign disappears.

Section 6 CALIBRATING PERFECTPASS SPEEDOMETER
(Wakeboard Mode)
If your digital speedometer is not accurate, you can go into the Speedo Cal screen of the
system. This is accessed by pressing the DOWN key with the highlighted on the main
Wakeboard screen.
We recommend you check and calibrate if necessary at 20 mph.
With the Calibration Adjust highlighted on the screen press either the UP or DOWN keys
to speed or slow the boat.
CASE 1. Boat speedometer reading lower then PerfectPass Speedometer
Press the UP key until the boat speedometer matches the PerfectPass
speedometer.
CASE 2. Boat speedometer reading higher then PerfectPass Speedometer
Press the DOWN key until the boat speedometer matches the PerfectPass
speedometer.
When the speed readout matches the boat or reference speed press MENU once to
highlight the then press the UP arrow to return to main screen.
Example: If you are set and engaged at 17 mph, but the analog speedometer or GPS is
reading 18 mph, go into the Speedo Cal screen and press the DOWN key several times
until the boat speed drops to 17 mph so the PerfectPass Digital Speedometer matches the
GPS or boat’s speedometer.
Paddlewheel Factor – This value is the actual calibration value much like an RPM
baseline. This number can be used to quickly determine where the calibration is at when
troubleshooting the paddlewheel. This number is also very useful when trying to set
calibration to match another system or to reset the calibration after a system RESET had
been performed.

Section 7 Driving Tips
1. Always pull a rider up smoothly. If you accelerate too far past the target speed,
you can gently pull the throttle handle back to assist PerfectPass in taking control.
When PerfectPass engages you will hear an audible “beep”. In addition when
engaged the Modes (Wakeboard) or Name on Screen will become highlighted.
2. Always leave your hand on the throttle and keep an eye on the lake ahead. Pull
back throttle to neutral to stop boat. (The system will immediately disengage and
the boat will be under manual control).
3. When returning to a rider in the water, drive very slowly and carefully. Always
turn engine off when loading or unloading a rider from platform. Never back a
boat up when someone is in water behind.
4. The speed based mode is not designed for skiing & speeds over 25 mph as the
control may not be smooth. RPM or Slalom mode is designed for smooth control
over 25 mph.
5. “More throttle” If you see the # sign on the screen, this means PerfectPass is
running out of control room, press throttle handle slightly ahead until the #
disappears.
6. You can temporarily over-ride the system by applying more throttle. The engine
speed will increase for about 5 seconds before PerfectPass regains control.
7. In a turn, the engine may accelerate to maintain speed. If you feel it is too
aggressive, simply assist the system by pulling back on the throttle to help the
rider. As you exit the turn, slowly advance handle so PerfectPass can properly re-
engage.
