I have a 96 johnson 115 v4 ocean runner. the motor will not run over 3000 rpms i changed the plugs still the same. After checking the new plugs it looks like one cylinder is not firing. what would cause this thanks.

Re: 1996 johnson no spark?

what have you check and what are the results. compression, spark with a spark tester? fuel line for leaks? when were the carbs last cleaned and rebuilt? get a spark tester from the auto parts store, set the gap and 7/16 inch, do all cylinders jump the gap?
