Rpm all over the place!!!!
04 RXP, Supercharger just rebuilt...Sea Doo rebuild kit. 4" Kana intake, new 14/19 impeller and wear ring, oil level correct. 8100 out of the hole, quickly drops to between 7700 to 7800. When running WOT for more than a minute or two RPM's will drop to 7200 then climb back to 7400, 7500, 7700 and then drop again. I never see 8100 at WOT accept on launch!!!

Possibly the clutch,sounds more like a boost leak to me...Who rebuilt your Scer and what did they set the slip to???

Sounds to me that it can be possible for your intercooler to be leaking.
Still have your stock cooler or Aftermarket?

How does the ski run??Does it run good up till the point were the RPMs drop??or does it have some spitting and sputtering to it??

Ski runs good. RPM'S are steady at idle, strong out the the hole and hold steady at all RPM accept WOT. I can run WOT for a few minutes then all of a sudden they will slip to 7200. Its strange....its a "smooth" but quick drop. In other words all 3 cylinders are firing fine and the engine is running smooth...Its just a drop in power. The RPM'S will climb back up (again, smooth and steady) but they wont hold for long and they drop again. I rebuilt the SC. I did not shim it but I did notice that the slip was at the lower end of the torque range.
