Vintage OMC- User Manual needed

I recently purchased an older OMC which needs/needed some sterndrive work but hopfully it'll be a nice shape in the next few weeks. It's the 1972
120 model S mounted in a Seaswirl of the same vintage. I'd like to locate
a user manual which shows how to winterize and maintain it properly. I found a Seloc manual but it lacks blow-up pictures and user friendly maintenance walk thru's, I can't even find locations for all the plugs that need to be removed for winter storage. Was there a better user friendly OMC manual which I can search for?

 

Try a search on ebay, they seem to have everything. Maybe used books on Amazon?

Good luck,

Charlie
