[C320-list] Through hull for new AC unit

[Jack Brennan]

I probably won’t do it because I need to haul out in the fall or early winter for a bottom job and can get the through hull installed then.

But what I was wondering about was a Y valve at the engine intake through hull. Considering I wouldn’t use AC underway, the flow could be shifted to one direction the AC and the other for motoring.

The biggest danger, I suppose, would be forgetfulness. But sometimes there are other downsides you don’t discover until you implement your “great” idea.

Now that I think about it, you definitely should not tee off the engine through-hull because the suction of the engine pump could pull air through the AC water line and cause your engine to overheat.
