OMC came out with the 60 degree looper in 90 for the 91 model year, and BRP kept them around under the JOHNSON name until 04 carbed when emissions completely phased them out. Throughout that whole run they were basically unchanged internally from what I have found. They were one of OMC/BRP's longest production run engines without major changes to them like the V-6 loopers got(small bore for 2 years, standard large bore for 4 years, and then switched over to the lightened and choked finger ported engines for about the last 8 years). The only other engines I can think of that had a longer run largely unchanged would have been the 3 cylinder loopers(probably the longest running engine without major changes of ANY manufacturer), or the 2.0L MERCURY's. It should also be of note the 150/175 FICHT engines were basically the same engine internally, and I believe even the current 150/175/and small block 200 has it's roots going back to that first 60 degree looper.
