The 1920’s Johnson’s Model A outboards used Champion 7 sparkplugs. What are good replacements for Champion 7sparkplugs? Do they still may Champion 7 plugs?

Thanks for any information.

Cheers,

This chart shows D-16. I think you can still get those….

Prepare to be boarded!

If you really want to keep it original check EBay, they pop up once and a while. This guy has a used one.
