I have been trying to get my PP wakeboard pro on my 2000 X-Star working since the beginning of this season. The last couple seasons this PP unit on my boat has worked perfectly, but to my surprise, I kicked off this season with PP not functioning properly. My problem..as I approach my target speed, perfect pass locks in, the bars come up and the PP instrumentation indicates PP has control of the boat. Well, it doesn’t. The system is not correcting my speed. I have successfully executed both the linkage test and servo motor test the kind folks at PP have recommended. My paddle wheel is operating correctly as I have a speed readout on my PP display. To exemplify my issue, lets assume my target speed is 22 mph, and I settle the boat speed to about 24 mph, I can visually observe the servo motor letting out slack, but the throttle is not backing off. Slack just keeps building. Now, if I go 20 – nothing happens (except a # sign sometimes indicating the need for more throttle). What gives? What I have looked into: Bad phases – from what I understand this can cause the servo motor to not have enough strength to make adjustments. Well, I replaced both the servo motor and the cable running from the motor to the PP “brain”. BTW, this would explain the problem I’m having when I go 20 and my target speed is 22. Also, I passed the “servo” test PP instructed me to execute. Resistor/Heat shield thingy (not exactly what it is called) – it is connected to the outside of the housing holding the servor motor. I inspected it per PP. Nothing appears to be wrong. If there were, I understand this could contribute to the bad phase problem. Return spring is worn out – from what I understand this would cause the throttle to not be able to back off when PP is letting out slack (which is what is happening when I go 24 and my target speed is 22). The MC dealer notes that most likely this isn’t the problem and that they have very rarely seen this spring go bad. Possible bind in the throttle cable running from the servo motor to the throttle body – well I can inspect this and see that things are running “smoothly”. Does anyone have any suggestions? Has anybody come across a problem like this with PP? I no longer know what to investigate and I have worked with both PP and MC with no success. I really don’t have the extra funds to let MC take care of it – so I really would appreciate any advice. I hate to give up on PP – but myself and my crew have become Ace’s at driving without it – but is just isn’t that same – especially after having eaten the cost of having PP and now not having it work. Frustrating. Any comments are appreciated. Craig
