Coil change on Elgin 1957 7.5 HP outboard

[moxie-man]

I cannot remember. Does the green lead (which typically needs to be lengthened) get attached to the condensor while the black lead goes to the ground on the laminations. Also the elgin fixed laminations have the raised springy metal tab. Do I have to also epoxy the coil in place or not to hold it. Thank you ahead of time for the help.

If you are referring to the "OMC" coils, then yes, the green lead goes to the condenser and black to ground. A little JB weld epoxy is what I use when I transfer the new, "Made In China " coils to the Good old "Made In North America" laminates. The fit is already pretty snug, but I do it anyway, just in case.

Wedgie,

Thank you. I rebuilt a couple of not yet running 50ish single cylinder Elgins last year and will have to check the my wiring on the new OMC coils. The 7.5 Elgin has the fixed/raised metal tab but older elgins have a flat removable tab which typically breaks. I have installed new coils without the tabs and pushed them onto the laminate by hand. They appeared to be snug and not moving. Should I JB weld them to prevent slipping? Has anybody had an issue of coil moving over time when no tab or JB Weld has been used to secure?
