I am looking for manuals for my ancient Onan 4MCCK -1A/1A I think it dates from the late sixties, my boat is a 1966 Viking.
I have found some links to manuals from 1983 but these are too new and my gen is physically somewhat different from these.
Cummin Onan has nothing this old.
Can anybody direct me?
Thanks,
TRD
