Looking for ideas here- 1995 115 Evinrude. First had problem this spring, when I took off the boat dropped a cylinder a bogged down. It missed at idle then too, but after cleaning it out by revving the motor with the idle lever, it cleared up. Never happened again. But today I had the boat out for the first time since then and it happened again. I was cruising WOT and it dropped a cyliner and bogged down. I could clean it out but it happened right away again. Both instances happened with the motor warmed up after traveling a couple miles. I tried to foul the plug a bit on the way back to the dock, but after idling while docking it cleaned the plugs up pretty well. There is one cylinder that the plug has lots of oil on the threads and is a bit darker, so I am assuming it's that one.
I am going to replace all plugs. But this seems like a bad coil. What's the best way to test. I can swap coils to a different cylinder. It's tough to get to the wires while it's running. Maybe get it to miss, then stop, pull off the wire, and try to go again? I am also going to clean up all the grounding points tonite. Any ideas? Powerpack? I am reviewing th CDI troubleshooting guide tonite as well. Thanks!
