[C320-list] Through hull for new AC unit

[Bruce Hunter]

I tee'd off the engine cooling seacock after the sea strainer. I also put a ball valve before the A/C cooling pump and another on the hose going to the engine's water pump. We keep our ignition key in the area of these valves.

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.
