People put all kinds of words in the ad to get a hit on a search.That's a 12 degree model - first hint is the fuel tank being in the belly. The fuel tanks on the (60's and up through '71) models were inside the console (as well as the early 170s).The 191 models were the ones that had the unique bottom that was near-flat and were made through '71 (same last year of the 222 FB).
The first year of the 196 was '72, the last year of the 191 was '71.The two models of the 191 were defined, in essence, by where the console was placed - I guess it's all about the room behind the console? I'm sure the boats ran a little different since the console had the fuel tank inside it and they were moving that weight forward and aft.The Gull had the console up tight and even on top of the casting deck a little.

The casting decks were large too.
