    Coincidentally just checked mine.

    On my 2012 GTI 155 with 210 hours, I had about 182 on all 3 cylinders.

    The normally aspirated engines run higher piston compression ratios.
    What is the spec for the compression psi on a 155hp?

    I can't find any documentation with stats. The FSM only states to do a leak down test; nothing in there about compression testing.

    The local BRP service advisor told me 180-200 is the goal.

    My friends 2012 GTI 130 had similar, but slightly higher numbers.

    Good luck finding any (official) compression specs on a seadoo! 180-200 seems high(?)
