I was given this outboard engine. It is a Simpson Sears Elgin 2 outboard engine. It is a Canadian model, thus getting very difficult to find related info.
Engine is a Tecumseh, according to sticker on starter cover. Tag on carburettor has: T636 08A serial number 450 7232. Tecumseh shop manual deals with engines models starting at 638-670. Looking for parts, IPL, shop manual, owner's manual. Pictures available here:
