I have a 1964 Evinrude Sportfour 60 hp motor with NON electric shift. I know a handful of outboards shared similar lower units. Does anyone know what years, hps, and manufacturers may have also used this same lower unit?
I haven’t checked Phil’s list, but he probably is correct. In short, the V4-60 never had electric shift, so you can eliminate all electric shift lower units. That leaves all the rest of the V-4 OMC outboards that do NOT have thru-the-prop exhaust. Exceptions would be the 50hp and the later ones that used the "Heavy Duty" lower unit, the heavy duty one actually being the old 50hp. However the heavy duty will fit if you prefer one.
