I think I have the owner's manual that includes that series of engines, but it's on my boat, on the hard, in Maryland...and I'm living in Ohio for the winter. If you don't find it elsewhere, check with me in about April, and I'll make a copy and send it to you.

What is it you're trying to determine? I have all the manuals for 4gm and some of the stuff is common to all engines. Maybe I can give you what you need.

It should not be too difficult. The only fiddly bit is how the alternator wires into the loom. They really are quite simple wiring diagrams, at least compared to motorcycles, for example.
