Re: 1998 gp waverunner
It sounds like you have a fuel issue. From the symptoms you've provided I think you need a carb rebuild with new needles and seats. I think your needles are not shutting causing gas to continuously dump into the carbs and run like crap. 110 is actually low for compression. I think you should be getting closer to 150psi. However, if your gauge isn't calibrated, that would make sense. That's my guess since all three are the same psi.
