MB I see the same as you do on those 3 links - first two the member deleted his gallery, so no pics left.The 3rd everything looks fine. I see all the pics in the bunch of links CB posted first.I don't know which threads you are seeing Xs in. One thing you might want to do is reset your browser back to factory to clear out everything. Google how to do it.Self Bailing is just what Capt Bob explained. My '71 170 was just that, the top was sealed from the bilge and there were 2 1" scuppers in the well right below the engine.As motors got bigger starting in the 70s and the clamp standard changed the boats were weighed down in the aft putting the scuppers under water - no more self bailing.The garboard is the plug at the bottom of the "v" in the aft, to drain the bilge.As for the seats, I think if you want the exact same type of seats you may have to make them yourself unless you stumble onto some at a surplus place from a different brand boat. Making them would not be hard and there are a couple examples of people making their own here.
Now my question is why did they run the gas line and the electrical for the sending unit above the deck floor. I believe I have read that the spray foam is sealed and is a pain to run the original route, am I correct on this and what is the fix I don't want this above the deck.
