New to this forum and to the Evinrude Lightwin. Mine is a 1960 model, it seems in good condition and in terms of design is light-years in advance of the Seagull I have, and I want to keep it that way! I am confused as to the correct fuel/oil mix. I contacted Evinrude and was told 50:1 was correct, but the engine was made at a time when 25:1 was current lubrication technology, and others have suggested 16:1 might be appropriate. Is there any definitive advice out there?
By the way, is there any salt neutraliser I might use for flushing? I will be using the engine in the sea.
