    Default I am new at the boat thing an

    I am new at the boat thing and i am unsure what spark plug to use. The table says if it is a omc or bmc to use a spark plug number QL77JC4 and all others to use a L77JC4 for a 91 johnson-evinrude. How do I tell what it is.

    Default OMC = Outboard Marine Corp.

    OMC = Outboard Marine Corp. BMC = Bombardier Marine Corp. Bombardier bought OMC a couple of years ago. OMC/BMC manufactures Johnson & Evinrude marine engines.
