I am looking at possibly buying a 115 four stroke. The seller provided the following information via photographs. The sticker on the transom mount shows Model # 1115F23ED, the Serial # 1B816847 the next line down shows 115 XL 4S. I have been googling for an hour and found a chart somewhere that showed the serial # fell into the range of a 2006 motor. The second picture provided by the seller was the 2010 Emissions compliance decal that showed June of 2010 in the lower left corner. Having read too many posts this afternoon I have decided don't know how to identify the year this motor was made. I assume the emissions sticker is the obvious answer?
