Re: seahorse 5.5 speed control ?????
You found a '56 model in the attic with no spark and because of this you're going to junk it?????

There's not a '56 model motor in existance that has original coils that actually has spark. Those are smooth running motors and with a little work, there's a great chance it will run like new. If you're interested in repairing it, you might check out the "top secret files" thread at the top of the johnson/evinrude forum. There's several threads that will tell you how to get good spark--"points and coils" thread, and how to adjust the carburetor, etc. Those carburetors are extremely simple and reliable and you shouldn't be scared at all to take it apart. You will have to take off the powehead to get the lower unit off to change the impeller, but it's easy to do for anyone.
Since you're taking it all apart anyway to part it out, you're not out any work.
If you have no need for the motor, why not just sell the whole thing and save yourself the work?
If it is a '56, then the face plate will come off after you remove the cowl and take off the knobs from the carburetor. I'm worried it may not be a '56 because the face plate is really easy to take off. Got pics??

There's pictures of all the parts and their names in the "points and coils" section of the top secret files, if you need help identifying the parts.
Good luck with your motor, it's probably a good one.

BTW, Welcome to iboats!

There are lots of folks like me here that love those '50s OMC outboards and there are several absolute OMC geniuses here that would be more than willing to help you fix your motor. Myself, I had little experience fixing outboards a few years ago, and with these guys help, was able to get every OMC I've ever gotten running well. I enjoy working on these because the engineering is so ingenious, yet simple. They are made so that they are easy to work on with common tools as well. You can just about totally disassemble that motor with a 7/16 and 1/2" end wrench and a flathead screwdrive.
---hope you'll return with some "how to fix it" questions......:redface:
