Not that I can add much about the V-drive itself, but what are you looking for?
It's a vintage v-drive gear box out of a pretty neat looking vintages flat bottom. In the right hands that would be a fun little restoration project and would be neat to restore " old school". Love the small exhausts! Do you have any more pics of the boat?
I would guess the boat is 1960's with that style plate on the transom.
