Section 9 Installation Instructions
PerfectPass Wakeboard Pro
Step 1. Installation of Servo Motor
Using the two provided hose clamps, loosely mount the servo motor on top of the cooling water
hose leading to drivers side exhaust manifold (starboard side on standard inboard engines). See
Figure A. Tighten later after final positioning. (See amended installation details “Photo” if
inserted for certain engines for servo motor mounting position).
Remove ball joint connector from throttle control lever and remove from the coupling end of
Morse control / Teleflex cable. (See Figure B).
Position servo motor throttle cable in line with the throttle control lever. Ensure the locking
10/32 nut is in place on Morse control / Teleflex throttle cable. Screw threaded brass hex
connector on the PerfectPass cable onto the end of the Morse control throttle cable. (Do not
over tighten hex nut). Install L shaped brass throttle adapter to throttle control lever using
identical hole as original ball joint. (L adapter must be able to swivel). Using an Allen key,
tighten L shaped adapter mounting bolt. (See Figure C). You may find it helps to move the
Morse control lever into gear during installation to allow more clearance. (Be sure the washer is
against the brass L-Adapter and not under the nut).
Check and adjust position of servo motor ensuring the motor box cover closes properly and
servo throttle cable is not in contact with any moving parts. Make sure servo motor cable has 2
or 3 inches of free travel. Securely tighten hose clamps on servo motor. (Do not “tie wrap”
cable as it must be able to move freely).
With the throttle in neutral position, adjust brass hex connector if necessary to ensure there is no
gap between it and the end of the servo motor cable (any gap may cause engine to surge up and
down in neutral). Adjust and snugly tighten all parts. (See photo’s, DO NOT OVER
TIGHTEN).
Turn the black servo motor knob in a clockwise position until snug. With throttle in neutral, the
linkage should appear as in Figure C.
Linkage Test – This is a quick & easy test to check throttle cable & linkage.
With key OFF, push throttle lever to ¾ open position. Now take the black knob on servo motor
and wind it counter clockwise a full turn and then clockwise a full turn. Do this slowly in each
direction and as you do this the engine throttle arm should be opening and closing very
smoothly. If the cable is “rubbing” or “catching” on a fuel rail or decorative engine cover, the
servo & cable should be repositioned to eliminate this. The stainless cable inside the black
jacket MUST be able to seamlessly move for the control to work properly.
With key off, push manual throttle to full open position and back to neutral. PerfectPass cable
should move freely in both directions.
IMPORTANT: - Never “tie wrap” PerfectPass throttle cable.
- Make sure all wires are tied away from hot or moving parts and there is
adequate clearance.
- The manual throttle on your boat should operate and feel the same as
before the PerfectPass was installed, or you may have to adjust the hex
nut.
