Very Interesting.
You could have a Four Winns Dealer look up your Hull Identification Number.
I don't know what year that model changed. On my Horizon 240 I have the interesting situation where mine is a year 2000 (including the HIN#), but it is the last of the 1996-1999 model types. Later in 2000 a new model Horizon 240 came out (different from mine).
