      1966 Evinrude seems to be running on one cylinder.  Use it one or two weeks a year for fishing,  Last week after using all week on Friday it seems to run on one cylinder.

        very basic  magneto to service…

        try a new plug on the cold cyl.

        measure ohms from plug boot to engine frame   xpect 4-8kohms if coil is not defective

        when was the magneto serviced  to inspect for cracked coils bad condensers dirty points   etc… lot of info available if you want to jump in and fix it free  instead of paying $100/h  plus parts…….. lots of help here  and your only costs will be available parts if needed.

        This could be as simple as cleaning the points associated with the bad cyl…  front coil feeds the top cyl !!

        here are a few docs to read plus you have tons of utubes to fix  magnetos used from early 50s to late 60s    print this manul

        this bible on “older” motors covers magnetos extensively plus lots of outboard  concepts to learn

          Sorry, I’m in RI, hoping someone closeby will read this and can help out, or perhaps recommend an experienced OMC shop.

            shop repair/time  may cost more than the engine value !   ….why not give it a try.   a lot of times it is only a cheap part like a condenser or dirty points.

                  There is a club chapter in northern Ill. Here is a link to their website. http://www.motorheadsil.com/ Click on events and you’ll see that they are having a meet July 25th., about a hour from O hare. If you can make that meet you may find someone that could help you. If you decide to go, bring the motor.

                  A "Boathouse Repair" is one thats done without having tools or the skills to do it properly.
