    1988 Mercury V175 - Compression on all cylinder 135 psi - Is that good?

    I checked the compression today and it was 135 psi on all cylinders. Is that in range for a 1988 Mercury V175?

    That's actually VERY good. There is, however, almost always SOME variance.

    If you need further assistance, the 2.0/2.4/2.5 Liter Forum is specific to your engine type.
