When I bought the boat back in 2003, it had fairly recent Ocean Breeze condensers. They worked really good and seemed well built. I had to call them a couple of times over the years and got good phone support.
Another great AC manufacturer is Flagship. I installed two of their chillers and 5 air handlers about 3 years ago. Solid construction, all SS pans with good drainage unlike cruisair. They make splits and self contained as well.
Anything but cruisair. Getting parts is terrible. Right now I have a bad blower on a air handler on the 84 I run and it s back ordered till mid July. Boat is for sale... doesn’t look good when showing.
I had the original three knobs when I bought my 53... what a difference electronic controls make!!!
