Re: Lower Units that are compatible with my '67 Johnson 80hp?
Need to know if you have an electric shift or a manual shift gear case. If it is a manual shift, any 1960 t0 1968 60, threw 85 HP manual gear case will work. If it is electric then any 1960 75 to 90 HP electric shift gear case will work. I believe, if it is manual even the 1958 &59 50 HP heave duty gear case will bolt on. If it is electric, I believe you can use the 66-68 100 HP gear case if you use the intermediate adaptor a long with the gear case.
