Our raw water intake for the AC used to share the engine raw water intake. We now have a separate thru hull for the AC. The AC Raw Water pump and strainer are located just above the transmission, just inside the rear access door in the aft cabin, easy access. There is a nice teak enclosure surrounding the AC unit, under the stairs, with vents forward to the galley area and aft to the stern berth. The air intake is a teak louvre on the side facing the galley. There is a shelf created as a result just under the top step with a fiddle surrounding, a handy place for small stuff just inside the companionway. Doesn't look like an add on at all, looks like it had been there when the boat was built.
The discharge hose runs under the fuel tank to a thru hull next to the others in the stern.
