Re: Need Manual for Johnny CD 12- 5 1/2- 1955
acmeoutboards.com sells the early Johnson and Evinrude OEM manuals on CD, which is a economical choice compared to the Kencook.com one. Since back then the service manual for all models covered in one book, these ones are more expensive to reproduce and rarer on ebay.
The Seloc isn't too bad. I have one in addition to some factory literature. But it has serious deficiencies in both the carb rebuild section and the link & sync section. Not to mention some outright errors. Where it shines is it's coverage of accessories, common issues, and explanations for the beginner.
It is probably not important, but the Seloc only claims to cover '56-70.
I do want to echo checking the local library though. I'm blessed to have one nearby that carries a few original OEM manuals in addition to the typical generic fare. At the very least, it's worth comparing what's written in a couple service manuals to get clarified on a procedure.
