Years ago I remember seeing a little suction bubble device that attaches to the AC inlet to allow running the AC when out of the water with a garden hose attached. But I am unable to find this device. Thought it would be great to flush the AC after use in saltwater.

No you do not need to flush the A/C. The condenser coils on most marine A/C units use titaniuim tubes which is not effected by the salt water. Just keep the sea strainer clean and you should be Ok.

Great! And thanks, at least one item that I won't have to worry about in salt water!!

Very few marine condensers are made from titanium. Indeed some are, but most are made from Cupronickel for the following reasons:
1.) Up to 350% enhancement in BTU/hr transfer
2.) Increased internal burst pressure and compression strength
3.) Lower cost compared to other specialized tubing (ie. titanium)

Regardless, there is no need to flush your system, it will handle the salt water.

From Wikipedia:

Cupronickel or copper-nickel (sometimes incorrectly referred to as "cupernickel") is an alloy of copper that contains nickel and strengthening elements, such as iron and manganese. Cupronickel is highly resistant to corrosion in seawater, because its electrode potential is adjusted to be neutral with regard to seawater. Because of this, it is used for piping, heat exchangers and condensers in seawater systems as well as marine hardware, and sometimes for the propellers, crankshafts and hulls of premium tugboats, fishing boats and other working boats.


I wonder, does it still retain the natural biocide properties of copper? If so that would mean marine growth would not be an issue. Just keep the strainer clean.
