Hiya .. I replied this to your rec.bots.building post as well ... I have an
'83 MCM 185 (V-6) 3.8 litre mercruiser (GM) ... it's an odd fire (check the
distributor cam ... sharp lobe, round lobe, ... ) with a 4bbl ... does that
sound close? If so, the Seloc Mercruiser Stern Drives 1964-91 Repair Manual
#3200 should tell you all you need to know.

Hello all, I have a 1985 19ft Renkin Boat with the OMC 3.8L v6
engineand outdrive. I am trying to find out who manufactures the
engine. IE:Chevrolet or Oldsmobile? I need to buy cap and rotor, plugs,
plug wires and freeze plugs and I can't do this until I figure out
whomanufactured the engine. I been looking a lot on the Deja groups
andfound a few topics, I am thinking that it was made by Chevrolet/GMC
butjust want to be sure. Any help you guys can provide me would
begreatlly appriciated. Also would be helpful to figure out which
outdrive I have as well.


Thanks, Radman....
