      I have been working on restoring this beautiful old Evinrude outboard and everything is in really good condition and the restoration is going well I just started into the ignition system and have a few questions I’m replacing the plug wires with 7mm solid core wires since the old cloth has deteriorated but I measured the coils and am getting and open circuit is there an aftermarket magneto coil and condenser people are using? If not is it possible to rewind the coils and does anyone have the specs on that? Thank you

        Are both coils showing an open circuit?
        Photos and coil & laminate measurements may help with solutions.

        BTY, I just picked up two of the 1934 Lightwins, but have not started
        working on them yet.

            and here is the bottomside both of the coils are measuring open resistance unfortunately

                I wonder if Evinrude Zypher coils would work?

                Another option may be to use the Military Scintilla style coils,
                but, if possible, lots of monkey business involved to get them
                to fit on the laminates.

                  That’s a great idea do you have the dimensions on those coils?

                    I can look around the garage tomorrow to see if I have a loose
                    Zephyr magplate to take some measurements, but perhpas
                    someone has the information recorded.

                    What are the dimensions, bolt center to center on your coils?

                      Zephyr coils are the same as the coils in your motor. Before you pay for a replacement, have the seller check to be sure it isn’t open like yours. Pretty common with this coil. Also be sure the wire connection is tight and doesn’t move if you try to twist it. Use caution when removing and connecting the plug wires and installing the coil.

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

                        Before you go too far, confirm that you measured the resistance at the coil, across the two wire connections.  If you measured from one lead to ground, you would expect to see an open circuit.
