If you want a guaranteed fix job on Johnson go to Schwarzel Marine in Hocking Port Ohio.

It's a long way from Louisville and Lex but I've taken my old Johnson there a couple times. They are master Johnson technicians. Been selling and servicing Johnson/Evinrude for decades. John and his son do all the work, know all the service bulletins by memory and will adjust things you did not ask them to do to make it right. Can't go wrong. The way I figured it was, one long drive in the winter vs maybe a take back or two in prime fishing season.
