I have a 2006 VX110 Deluxe that I sent to a repairman to replace my Impeller because it was running rough. Just got it back and now it will not go over 5000 RPMs at 7mph. It seems to feel like it is in L Mode, although the L Mode light is not on and when I turn on the ski it only beeps twice. When I put in L Mode, the light comes on and it beeps 3 times it runs the same speed as in normal mode. My repair man says that it could be the computer going bad. Any ideas of how to fix this?
