      I have a 1955 1.7hp Neptune, and the coil is junk. (it’s falling apart disintegrating)  Can anyone tell me where I can see about getting a replacement or what I can use from something more modern to replace it? I was told of a place called Standard out of IL where a person got some but I haven’t been able to find the company.

      Is there any way to change it over to electronic ignition?

        Call Standard Magneto sales. 1-773-235-2010. Maybe they can help.  If they do not have a direct listing, they will need to know the measurements of:                                                       1- the steel laminate square or rectangle protruding through the center of the coil (1/2” x 9/16” or 9/16” x 9/16” as examples.

        2- diameter of coil.

        3- length of square or rectangle part of coil the goes over steel laminate.

        4- manufacturer of magneto assembly (Wico or Eismann or Phelan as examples. The magneto plate should have the name embossed on it somewhere. If there is also a service number stamped into the plate, write the number down.

        you can also email or text a picture to them.

          With some effort, you can replace it with the common, & inexpensive, OMC style coil.

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

              Thank you very much sir! I will have to give this a try! Could you recommend a make and model of a year of motor that would have a small coil? the one in my 55 is very small. I have a coil from a 66 Evinrude 6hp but the coil is to big in width.  Thank you

                The OMC coil swap may not work.  You need to measure the depth of the coil. The OMC may be too deep.  I tried it on a 1939 Neptune 1.5 hp and it did not work.  The original coil was a Wico setup with a 1” depth tube and OMC was about 1-1/4” deep.  I contacted Standard Magneto Sales with no luck but Doug Penn set me up with coils I could use for the 2 motors I have. I had to swap the coils from the new laminates to my old ones.
