Not one to complain much but... nothing on our family "project" seems to match. Our Sea Ray Monaco 187 was built in 1985, the engine is a 4.3 262 CID, labled on the top 185. It however has a 4 barrel carb, with points type ignition. None of these items seem to point to one specific "this is what you have" choice in any online information charts or forums.

I'm looking for this information for a necessary tune up! I would like to replace the coil, distributor cap, wires, plugs, points, condenser etc.

The distributor cap and rotor I simply took in with me to match up. But - what are the proper spark plug, and coil replacements.

And would like to set the timing. I would guess that setting the points at approx .02 and timing at 8 to 10 deg BTDC would be close but?

So - I read someone else's post "off-topic" found a link to manuals and I'll download the GM v6 568 MB file and take a look.
