    Compression Number for 05 GTX NA

    Well I just purchased this ski and yes I did a water test and it did great... It just seems that everything is breaking on it all at once now before I even get it in the water. Seems to be a trend of mine. Anyways I did a compression test and all cylinders were at 185. I havent found the spec for it in the service manual but was wondering if that sounds about right? After everything that has broken on the ski I know for a fact it was pulled and possibly rebuilt, just not sure what was replaced on it.

    185 sounds like a good number to me. The biggest thing is if they're all within a few PSI of each other.
