I am having a diver clean my 2007 320 sundancer for the first time. It is has 2 350 mercs with a v drive. From what I have researched I think there is a bar on the transom and one on each of the trip tabs. Are those the only ones on the outside of the boat? I don't see anywhere that there is anything on the props or anywhere else outside of tthe ones in the bilge. thx
