Section 9. INSTALLATION INSTRUCTIONS
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 (or as specified in any
Addendum photos).
Remove ball joint connector from throttle control lever and remove the coupling from end
of Morse control / Teleflex cable. (See Figure B).
Position the servo motor throttle cable in line with the throttle control lever. Ensure the
10/32 locking nut is in place on Morse control / Teleflex throttle cable. Screw threaded
brass hex connector on 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 next to 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 the servo motor
cable has 2 or 3 inches of free travel. Securely tighten hose clamps on servo motor. (Do not
“tie wrap” the throttle 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 photos,
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.
Servo Motor / Cable Testing
- It is vitally important that the stainless steel cable inside the
plastic jacket has the ability to move freely or the system will not perform properly, may
hunt and not settle down. The alignment of the PerfectPass cable and the boat’s throttle
cable should be straight.
