The model number should be on a 1" X 3" metal plate attached to the port transom bracket.

Failing that, look for a nickel-sized, convex welch plug on the top of the engine block with the numbers.

Once you have the numbers, check back here.

Yes, 1977. That's the last year in that particular series for the V4 85HP and 115HP. They were built from 1973 - 1977.

Use 87 or 89 US Octane gasoline with TC-W3 oil, Hi Vis gear oil. I had best luck using QL77JC4 Champion plugs and synthetic TC-W3.

See if there is any movement of the tachometer when you turn the ignition key to the run position. You may have a bad rectifier; check it according to this thread by Mr. Joe Reeves: http://forums.iboats.com/showthread.php?t=190638
