I have a 1992 evinrude 60 hp outboard. The number 2 cylinder failed and I am in the process of rebuilding. I did a search and found that there is a common problem with the number 2 cylinder overheating and failing. I found info on the service bulletins and pretty much have the part numbers for all of them but one. It is SB 2271 and has to do with changing the timing and high speed jets. Apparently it only is for certain outboards. Also, someone mentioned that they changed the mid range jets also and had better results. Anyways, I was wondering if anyone had access to the bulletins or could tell me the part numbers for the jets. The other bulletins are sb2225, sb2276 r1. If anyone has the bulletins or info on them, please let me know. I hate to put this thing back together and have the same problem happen again. Thanks.
