OMC cross flow and looper outboards

Can anyone help me with any details as to when the OMC cross flow motors were ended and the loopers started in the 150 class to the 225 class. I think it was in the eighties, but I am not sure. How can one tell the difference with the hood off.
I have an 88 150, a neighbor has a 86 225. Decal patterns are very similar. Do we both have loopers?

I think OMC introduced the loop charged 200 and 225 (big 90 degree V6 block) in either in 1985 or 1986. I believe OMC introduced the loop charged 150 and 170 (small 60 degree V6 block) in 1991.
Your neighbor has a loop charged V6 and you have a cross-flow V6.

For a comparitive reference, the Mercury 60 degree V-6 loop charged block came out in 1976, patent expired 14 years later.
