This is a new-to-me 1966 3-hp, 20" folding-shaft Evinrude. I bought it on eBay and there is no manual. The engine starts and runs. For whatever reason, the prop does not turn. There appears to be no "Forward" button or lever that I can find. I can turn the prop by hand although it is a bit stiff. Suggestions? My local Evinrude dealer is too busy to return my calls about this. Thanks for your responses ahead of time.
