    Ideal Compression on a Used Outboard

    Hey guys just curious, whats the ideal compression for a used outboard. Would u be concerned on a 1997 Johnson Faststrike with the compression check coming in around 100 for each cylinder?

    Even numbers on compression readings is what you look for. 100 psi on that engine is good.
