    My  2013 188 merc 4.3 I/O had OBD( on board diagonistics) light came on summer 2015 and dealer cleared light- minor sensor out of range.  The OBD light came back on this past summer and still on.   I will have dealer clear before it is put in storage.  As with an automobile the light can mean a big issue( like timing off) or small issue ( gas cap loose).
    i hope it is nothing.
    You should have your dealer clear light and fix issue if any.

    In addition to answer your specific question and clarify,the OBD light should come on(yellow) after you turn key on(4 seconds) and go off before you turn ignition to start -in order to self check.
    if everything is ok the OBD light should be off.  If fault is found it will stay on until corrected.
    i believe Mercury has a technical service bulletin on issue.
