I have a wealth of material pertaining to OMC's first generation Stern Drives as well as OMC boats 1962-1970.
Eventually it will be ported into the Fiberglassics site for the benefit of all. In the mean time, I thought I'd post the links to some items. These links will take you to OMCboats.Org where you'll find PDF's that you can download.
You may need to rename some of the downloads to avoid problems opening the files. If your download shows the file name with the .PDF extention, delete that to avoid a double .pdf in the name.
