1977 75 hp no spark Evinrude wiring diagram

[butch's place]

I bought a boat with a 1977 Evinrude motor that ran when purchased. I pulled it home and now it does not have a spark. I'm looking for a wiring diagram to help me find the problem.

Get a good factory service manual, it will include a nice big wiring diagram and more, I prefer those, but Im sure this one online will do.

Thanks, I found a manual on Ebay and it is a big help and I can't wait for 'warmer weather' to dive into it. My shade tree doesn't protect me from the elements.
