What's my problem?

[WBLskier]

Help me diagnose my perfect pass problem. I have a 98 Malibu Echelon with a Monsoon engine. I have the most recent PP software and run zbox. It has always been super dialed in. I let the kids use the boat and one of them who drives ZO all the time was taking a tricker at 15'ish and after PP engaged he put the throttle all the way down as you can with ZO. The next time I used the boat two things happened: (1) to get to 34 I had to put the throttle all the way open when that would normally get you to high 40's; and (2) the PP beeps like it is engaged but can't regulate the speed now. Somehow the throttle issue seemed to resolve itself (it feels the same now as before). I did the servo test and it looks pretty tight but does shake at the end of tightening up (not sure if it did that before or not)...so maybe servo broke? My other thought was the extra spring I have on it may have gotten stretched out, but that I believe is there to get it to hit speed faster not get it there entirely. Any suggestions would be appreciated.

Shaking is normal on power up thightening.

Check all settings in PP,if not working i would factory reset and recalibrate everything...

I tried resetting it. It can’t seem to slow the boat down. Couldn’t slow it down to 34.2 to set the baselines. Electronics seem fine.

Did you check for proper adjustment where the PP servo cable connects to the carburetor throttle control lever on the opposing side of your regular throttle cable? Also, be sure the servo motor didn't move any from it's mounting position in a way that could cause the cable to catch on something. See Installation Instructions in the PP manual to verify everything still looks good mechanically.
