Thanks to both responses. I spoke with a cruisair Tech yesterday. He also said there is a power relay box and that that is a good place to power check.  Since early 2000's he said the fuse requirement in the system was removed. I'm a 2010 build but i'll look behind the panel anyways. OEM (Queen Long) may have still used them.  I doubt 3 of them blew simultaneously but you never know..... it's a boat. I suspect the pump may be original and it may be time for a new one. Fortunately, it is very accessible in the top part of the bilge. Again, thanks for both suggestions and i'll post my findings/solution when I get to fixing it.

There is no fuse that I know of.  However, when multiple AC units share a pump there is a relay box that takes the signals from the units and turns the pump on/off.  Find that box, mine is behind the instrument panel at the Nav-station, and look for possible problems there.

Our a/c circulation pump is fused right below the breakers for each A/c unit on the main breaker panel.

Does anyone know if the air conditioner cooling water pump is fuse protected?  If so, any idea where that fuse is located? Hoping its a fuse and not the entire pump that is inop. Unfortunately, that one pump supplies all 3 A/C units, so no pump, no A/C.
