[QUOTE="airshot, post: 73899, member: 1183"] That far back there were more than carb differences, I had a 1994 9.9 that was in fact a 15 with a restricted carb to reduce it to the 9.9 hp. This was all confirmed by OMC at the time, the dealer sold me the larger carb (much larger) bolted it on, adjusted the mix and I now had a 15 hp. All timing, gear ratio, bore, stroke, and all else was the same. You may have to change the prop pitch as the 9.9 prop has less pitch, but it was only in those early to mid 90's that this conversion was just a carb. Airshot [/QUOTE]
