Hi, i have a 97 sl900. It runs great on the trailer of course, starts right up no hesitation, and revs all the way out. I just recently rebuilt the carbs on it. The problem i'm having is when i get to the lake and put it in the water it seems like the ski only has half to 3/4 the power that it should. I know that in the water i should be seeing over 6000 rpms, i'm only getting something in the 5600 range i believe, hard to see my mfd as part of the numbers/letters are faded on the display. But i have ridden enough of these to know it was way low on power, i have good spark, good compression, rebuilt carbs...what else could it be or where should i start now?
