Hello everyone, new to Greenhulk. Thanks for your time. I own a 2004 Seadoo GTX SC and the other day I was jumping waves. At first things were fine, then a beep was given and rpm dropped and a second later the throttle kicked back in and powered up. I would then jump a smaller wave then same thing over and over. The ski would only run normally when I did 1/4 throttle over waves. There is and error code that I have but I have been having it for years with no problem and that code is the knock sensor code (i forget the exact code P-0362 or soemthing????) Any help is appriciated. Thanks in advance.
