    Default 1994 Mercury Mariner 3 cylinder

    I'm new to this (boating ) Just wondering if anyone can give the compression values for a 1994 Mercury Mariner 3 cylinder 50hp , I did the test last night and I received values of (from top to bottom ) 110,110 and 112 ? not if that's good or bad
    Thanks for your help

    FWIW, you will get better results posting in the Mercury/Mariner section for your outboard.

    without knowing the details, I'd say your engine is in serviceable shape...the key factor is minimal variation between the three cylinders...
