I just purchased a ac/heat unit for my 28 mariner. I was wondering where the factory location is.

Does anyone have any suggestions on how to do this. I've been told to cut a hole in the salon floor and remove most of the engine. I've also been told to cut a hole in the hull and slide the tank out laterally. Which is the best way to do this; personally I don't have a clue. By the way, I'm not going to do the work myself. This is beyond my capability. Any ideas on this will be greatly appreciated.

My wife and I have a 42' Aft Cabin Carver. Our homeport is Smithfield Station, VA. We like to cruise the James River and tribs as well as the ICW.

how do you remove the fridge on a 1987 carver mariner, i don;t see the hold down fasteners

On my 81 3007 aft cabin, there are two water tanks, one port and one starboard. My starboard tank was disconnected at some point for some work on that engine. The question is, how are these tanks plumbed and connected together? It almost looks like the inlet Ys off to fill both tanks, and the draw from the pump also is Y'd to draw from both tanks???? Am I wrong? Any help in how this is supposed to be plumbed would be helpful.
