Re: omc pre 77 stringer manual non clymer
There is no comparison for an OEM manual for the model year of an OMC outdrive if you need closeups and detail information. There are some suttle differences in the model years 1968-1977. You would be better off if you narrow down the model year and then PURCHASE an OEM manual for the specific model year you have. Pictures of the complete outdrive, the boot and the boat hull serial # will help greatly. By using the above criteria, I was able to narrow mine down to 1 of 2 model years and then I used the BRP website to determine that the two model years were VIRTUALLY identical.
