i bought a used 9.9 fourstroke and can't figure out what year it is. The model # FT 9.9 EXD the lin below that says 668 UL 783 805. I need to pick up a couple parts/ owners manual and every site I go to needs the year first. I tried to find a lookup guide but they don't tell me the year they tell me everything else about it though. Thanks in advance.
