Hi got to use my newly bought rxp-x 255 yesterday. I need to know if she working right. The rpm are at 7650. The speed is at 63 to 65. But when I was riding over a bet of rough water and it seem like she was slipping. Now maybe the back end was coming out of the water. Plus later I hit on the gas and she jumped out of the water a bet and it felt like she slipped again, or was it the impeller again. The computer is saying the supercharger has 75 hour. Now when I bought it the guy said it only had 25 hour on it. So what do you guys think.
