THe water intake is in the vertical section of the notch 4" down and about 10" left of the drain plug. Inside the engine room, it comes in right above the bend that makes the notch.

Thanks.

That's where I'm leaning to install mine.

The intake line for the air cond. strainer runs along the floor of the bilge directly into the vertical plane of the notch. The strainer if fastened to the port side of the center stringer.

Is the water exit on the side above the water line?

My ac is under the sink in the cabinet, drains out the side of the boat.

Under the sink? Yours must be higher than mine. A perfect place too, no drilling thru the bulkheads to run the duct. Oh well. Might have to investigate that a bit. Does it sit down in a pocket below the carpeted cabinet bottom? Or is yours cooler/space/sink? Mine is cooler/sink.

Yes, its under the sink to the right of the door. It sits to the right of the drop in cooler. Mine is in a 2001 42 Lightning. Maybe there's a difference, but i doubt it. It has vents in the front of the cabinet and in the pod where the switches are located for the cabinet lights, fresh water pump, gen and shore power. I've seen one installed in a 35' (EX style) under the center cushion at the front of the seating. Vents through the front carpeted area. Dumps directly out the side just above the water line.

Now that you mention it, the bottom of the cabinet may be cut out so that it clears under the sink. I'll have to look at that.
