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....



OMC only used the Buick V6 for a few years back in the late 60's.

Your 3.8L is Chevy, and the forerunner of the famous 4.3L.

I noticed on the valve cover there is a label stating that it is a four
valve head, does that mean that there are two intake/two exaust valves
per cylinder? Is this always how these heads are on Marine engines? I
know on my old Camero it had a chevy 350 and there was only one intake
valve and one exaust valve per cylinder. Thanks.......

4V = 4 venturis = 4 barrel carb. Probably 2.02 intake valves, rather
than 2V 1.84 valves. I'm a Ford guy generally, but I think this is the
Chevy code...
