That's it, the Boat Inn, Bumblehole, Netherton, right in front of the canal boatyard and approx 1/2 mile from the Netherton tunnel. Doug Matthews was the Landlord and when he went to the Saltwells, his daughter Lesley and her husband took over. We still occasionally meet up with them and our old next-door neighbours.
Unfortunately the Boat, which was a proper Black-country pub, closed in the 1990's.
PS Sorry Nathan, forgot to thank you for finding and posting the photo.
