I googled around a little bit and found others who have had similar problems with other breeds. One of the obvious questions was, "Is he neutered?"

One response that made sense to me was to pick up the food and water dishes immediately after eating. If the marking is too quick, try cutting the meals in half. If there's no marking, give the second half, then remove the dishes.

And keep up with the vinegar cleaning. That should help.
