Before i get started i have wrote lavro an email, and may have to give them a call. But thought i would try for an answer here. I have a 1980 16-R Lavro db and it only has one drain hole on the right hand side just behind the front bench seat. This makes it kind of a pain to drain when i do happen to get water in the boat. Any how, it looks as though lavro may have made a spot in the right rear to have another drain hole drilled as it has been built up with fiberglass. But i am not sure. nor do i want to start punching holes in my boat. take a look. and give me your opinion.
thanks
