I'm new at this & even the shop manuals don't tell me. I assume this serial number OG129381 is for a 1990's 150hp V6 either XR6 or EFI or V-150. I have no way to tell what the year is, or the model. Mercury only tells me anything in ranges. I can't sell this engine until I figure out how to find things like 2.5 liter, or DFI or what the model actually is. You would think that just with a cotton picking serial number you could find all these answers online. here's some pics of this engine. I attached my blog link so you can look at the 20 pictures I took of this engine.
