Bob, I am in the middle of putting ac in my E40. When purchased it had a 16500btu flagship
marine unit that was poorly installed by a PO. It would not run for more than 15 min wtihout freezing up.
I, after a lot of
research, purchased 2 marine air vector turbo units. I am just now getting them installed. It is a bear to do. Not because the units are difficult to install. But the duct
work is.
The 16500 unit did a piss poor job of cooling, and I believe even if installed properly, would have been inadequate as well. I have a
center cockpit boat, so 2 units were needed. I put a 10k btu unit to mainly
service the aft stateroom with a small duct to the
salon, and aft
head. And a 12K btu unit to service the salon and forward
head and vberth. for a total of 22K btu. It is not operational as yet so I can not tell of it performance, but I believe the vector turbo is the best on the market at this time.
I purchased it from

I am in no way connected to Wright marine except as a satisfied customer. He has been very professional in all aspects, and his prices were good.
The units run thru a relay that controlls the march
pump, thru a
single strainer. The units are a lot smaller than the flagship unit. They have reverse cycle
heating. I upgraded the
shore power to 50 amp 120/240, but it would be a lot cheaper to just add another 30 amp
shore power to run them. If I can be of any further assistance let me know and good luck.
