After disassembly of my out board 90HP MERC 1989 3 cylinder I have noticed that the Mercury P/N on the trigger assembly differs from the one listed in the Mercury parts manual. P/N 99021A3 (manual) versus 99021A5 (part), can anyone tell me what the difference is between the two (other than the P/N). Are they interchangable?<br />Thanks<br />Will
