    1986 Mercury 25HP "No Pee"

    I'm sure someone knows exactly what I should do. Recently I acquired a 1986 Mercury 25HP S/N 0A97255.

    Compression

    1979 Mercruiser 260 HP - I have 105 to 120 PSI compression. And the exhaust really smells bad, not oil but maybe un-burnt fuel. How low is too low for compression and does stinky exhaust mean bad valves? Thanks, sr79
