There has been some talk in previous threads that 75/76/77 was so busy that production orders spilled over into subsequent years. Don't recall the specifics and might even be wrong on the generalities [img]images/icons/shocked.gif[/img] but there were a few people with similar questions to what year of their boat... It also might simply be that if your's ended in 1106 it was already in the 77 model year....
