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.

Maybe google it or possibly You Tube, if no one on here can answer you.

Wow Mr 88 thanks for the advice. I'm waiting for the outboard experts to chime in & help me. Truly awesome people, these outboard folks. They are the first to jump in & help anyone who is just learning, almost like an unrestrained, act of charity. But as for me, you won't see me posting a thread in this forum until weeks if not months of endless hours of research have passed, and then I come here when I have almost lost all hope in this business. The outboard squad always manages to save me.

Are you just starting out in a new marine business or something of the like and need help locating basic engine info?
