John,

Could you post your 1600BTU Turbo unit model?

Steve, thanks for the site. It's a good starting point. After getting details on the a/c unit I think I'll be on the right track in getting all the right parts. I hope that a/c unit has installation guide with all proper lines and dock work recommendations. I'm picking up good tips from you guys.

Alex,

I'll be on the boat for the next 4 days at the Apalachicola Sea Food Festival. I'll get you the answer tomorrow.

Update for all those the folks helping out with information on this subject. First off thanks for all the replies and help. I rechecked the flows this weekend and made some abustments. The 1,800 unit on Bridge now gets 307 gals per hour specs call for 375 gals. The forward unit gets 272 gals per hour specs call for 300 and the cabin gets 295 gals per hours specs call for 300. Here is some more data. The boat has a 1,500 gal pump as stated before. Total flow is 874 gals and the units at 100 % would need 925 gals. So you can see the total output is 51 gals less than what the units need and 626 gals below the 1,500 gallon starting pressure. Again, all the folks that know much more about this and responded describe why this happens. Hose sizes, curves, bends, dead rise and so on. I could make some more changes to increase flows. Think I will rest for a bit. Thanks to all.

Regardless of whether your unit is keeping the cockpit cool or not, the only thing that you unit is supposed to be able to do is reduce the temperature of a specified CFM of air a specified number of degrees. My first test would be to make sure you have the proper amount of air flow threw the coil. Check the temperature of the air entering the coil against the temperature of the air leaving the coil. For instance, maybe the fan is not turning max speed. Maybe the squirel cage is loose. Just throwing out ideas. Maybe check your air flow against a nother 16000 BTU in the marina. Measuring air flow is tough sometimes. Next you need to compare the temperature of the inlet cooling water to the outlet cooling water. This is just a hunch, have you tried forcing high pressure(dock water) thru the unit and see what comes out. I did this to one unit and a big chunck of green grassy goo plopped out. Have you had the Freon charged checked? Just because the unit is or isn't freezing up, doesn't mean the charge is correct. I have seen stranger things. Have you had someone put a set of AC gauges on it to see what the pressures are during operation? Just some thoughts.
