I have 40 hrs on the FX but I have a issue. She seems to run good but I can't get her over 40 anymore. I checked the intake grate and such which was clear and good. Impeller looks fine. She does great on the water just seems to have lost some speed and maybe a little power. Any Ideas where I can start??? I am a newb when it comes to working on pwc but not mechanical work. Just need a bone here.......
