Aggreed,If you haven’t already changed it, the shift rod seal [o ring] is most likely the culprit…. very common to leak on most 50’s and 60’s OMC outboards. Easy to change with the correct tools. When you have the lowerunit pressurized, try wiggling the shift shaft around a bit to see if it leaks while shifting in and out of gear.
