    I supercharged motor had about 125-145 a non supercharged has higher compression pistons so I would say probably higher than 145.

    Go to seadoomanual.net down load your shop manual and look it up!

    I think non s/c doos are around 180 psi
    As long as they are all close to each other on psi your good.
    Not more than 10% difference.

    I got a compression test done on my (previous) GTX N/A 155 and I had 165, 170, 170. I had 312 hours on it. Your #'s are good, but are you running it hard a bit? Are you doing your maintenance as scheduled?

    There's only 52 hours on the ski.. All maintence is being done one it. On the candoo software It's only been 10% of its life at full throttle.
