I have an '89 Bayliner powered by an 85hp Force o/b. I am trying to identify the outboard control unit, so as to search for a replacement, on the internet. Any help would be most appreciated. Stamped on the inside of the unit is "MERC"----"OMC" & "STD" I wish to more accurately identify it. If anyone knows of availability of this control, I would appreciate knowing about it. Thank you-----Jack
