I bought a 2012 RXPX260 with 116 hours on it. Rebuilt the jet pump and new wear ring. The ski would do 62ish all the time and sometimes I would get 66 out of it. I had the dealer rebuild the supercharger and install a scom. Still runs the same. compression is 120 in all cylinders. It says that the scom should make it start in sport mode and it doesn't. It seams to run fine and has plenty of power except for top speed. At wot sometimes runs hot like around 225. Any thoughts? Ski has 152 hours on it now.
