MERC URY has a welch plug in the block and there should be a metal tag on the port side of the pivot bracket I believe with the numbers. I'll try and get out tommorrow and snap a few pics of the tag locations on my old parts engine I have. The XRI's started in 89 with the 2.4L's, but that one looks like a 2.5L to me. I see the oil injection module on it, but no oil tank. Guess somebody rigged it up to keep the self test horn and water in fuel alarm. That rust in your pictures isn't major compared to some of the salty dog engines as those parts are just regular steel. TSUBAKI them pics of the welch plug you posted are of an OMC, you can tell by the OMC M stamped in it. That 200 is a good engine when it's running, but they are one of the fuel thirstiest 200 pigs ever built. The 200 XRI's are said to be 240HP LASER engines with a 200 exhaust tuner. You could always pick up another 200 carb motor and transfer the injection over to it.
