With key OFF, push manual throttle to full open and back to neutral. Does PerfectPass throttle
cable move forward and back freely without jamming or rubbing against cover, fuel rails, etc?
C. System surging in neutral – Check gap between the PerfectPass cable & the Morse control /
Teleflex cable. There should be No Gap. (See photo C in instruction manual).
D. System accelerates past set point – If the system accelerates past the set point and is very slow
to work back to the set speed, the engine throttle return spring may be weak. PerfectPass can
open the throttle, but depends on the engine return spring to bring it back towards neutral. A
spring can be easily added. It may also be a throttle cable / mechanical problem. See Linkage
Test, Section B above.
On Water Test – To confirm this, drive the boat carefully with engine cover open. Set speed at
a lower setting (i.e. 20 mph) and have driver engage system and press throttle up to 25 MPH.
As boat speed exceeds 20 mph, the servo should turn counter clockwise to let out cable and
slow engine. If servo counter rotates, the return spring should pull throttle back towards
neutral. If servo rotates but boat does not slow, the return spring is not pulling or something is
preventing the throttle or cable from moving.
E. No RPM tachometer reading – If the display tachometer reading is 00, check to make sure rpm
sensor is plugged into the correct port on Master Module. Check connections of rpm sensor.
(Check installation as per instructions).
F. Blown Fuse (5 amp, 1.25 inch fuse)
The most common reason a fuse will blow is if the red wire in the servo power cable is
grounded or shorted. Inspect the wire for any breaks, pinches or failure especially near the
gold resistor on the servo motor.
G. System Reset – If you would like to reset the entire system to original factory specifications,
you can do so by pressing & holding the ON/OFF & MENU Keys together as you power up the
system. After about 5 seconds the display will show [System Reset ^ = Y]. Press the UP key to
continue with a reset.
The next question will be whether you wish to reset all your baseline rpm values. [Reset RPM
@ ^ = Y] If you are happy with your baseline values, press the DOWN key and your settings will
be maintained. On some systems, you will be asked to select the engine in your boat. It will
then ask if you wish to run in just wakeboard modes [WAKBD ONLY ^=Y].
H. Change Display from MPH to KPH/Wakeboard only – Perform a “System Reset”.
I. Run in Wakeboard only Mode/Three Event Menu – To run in just wakeboard modes or to
return to the full event menu see (I) above.
J. Display is Hard to Read – Adjust contrast.
