My 04 Centurion has a manual wakeplate and they are a pain in the A$$ to adjust. I messed with it a couple times and never touched it again. The plate was fixed and literally had only a couple degress of deflection. I'm curious to mess around with it on the new boat and see how big of a difference it makes.
Let me guess you didn't get a fixed or "manual" wakeplate on the new boat? It's one of those things that ought to be stock and the seller has to pay for if he didn't pay for it the first time around. You gotta have it.
