    compression readings results.....

    Did oil change first then compression test.

    2006 waverunner fx1100 ho


    275 hours on the waverunner.

    I got similar readings minutes prior to treating it with seafoam cleaner.

    These readings both seem high considering usage, but obviously cylinder 1 concerns me but with it still being at a good compression should I be concerned with these readings?

    For that # of hours your good...
    Good compression is all cylinders within 10-15% of each other..
    All compression guages will give you different readings.
    As long as they are within 15% keep her Rippin on the water...
