I have no spark in #6 cylinder on my 1983 115 mercury tower of power. It ran great before winter but hasn't ran right this season. I replaced the coil, plug wire and plug still nothing. I need some help to figure this out.

I also have a 1983 115 inline if you are geting voltage to coil it may be a bad coil or plug , change number 3 coil with number 6 and test. if it still not fired it line up switch tripper then statro cdi is a good place to fine testing imfo

I replaced the coil, plug wire and wire. Still nothing. It was my understanding that if 1,3,5 or 2,3,6 were not working it was a switchbox....if two consecutive cylinders weren't working it would be a trigger and if one cylinder was not getting spark it would be a coil. I've eliminated the coil, plug and plug wire. Maybe a short somewhere?? Any ideas?
