Hello all,

I've got a '76 Johnson SR400 that needs some work. Primarily electrical.. I've discovered that a '75-76 Johnson 50hp outboard CDI can be substituted. Just
need to find replacement coils.. Anyone know if I could substitute the coils
from the '76 50hp outboard?

My thinking is the CDI's would/are paired with the ignition coils?

Sorry, I can't help with the coil info, the only thing I remember is that the system was very high voltage compared to other sleds and used surface gap plugs. Wish I still had my service manuals. Oh, and the 400 and 440 engines were identical apart from the cyl bore. I had a '74 JX400 and a '76 SR440. Post pics if you have any, I'd love to see one again.

Thx.. Unfortunately the sled is up north at the lake and I didn't take any
pics.. Probably won't get to working on it until the spring.. I did find this,
which is kinda nostalgic...

Yes, you should use the paired coils.
