1986 85hp force not firing on cylinder 3

Good day everyone,

Last year I got a boat with a 86 85hp force motor. It didn’t run at full speed when I got it. While checking things I shorted the rectifier with a screw driver. After that I changed the rectifier and it worked great. Until end of summer that is. Than the problem started up again. No spark on third cylinder. So come this season I naturally thought it needed a new rectifier, that it blew somehow. I changed the rectifier with 3 different ones and none made a difference. Tested them with a meter and they test out the same and only have continuity one direction as they should. I am curious if anyone has had similar issues or knows where to check? I’ve checked all the wires for continuity last summer and couldn’t find any broken wires anywhere.

Thank you
 
http://www.outboardignition.com/. They have trouble shooting procedures for your motor.
If it didn't run full speed before?? Do a compression test?? post the results.
Usually loosing spark on 1 cylinder could be the pack for that cylinder is bad(maybe) or the stator is bad(again maybe)
