Thanks for your input

As usual this group as been very helpful. I think I will go with a dedicated thru hull located near the exisitng main raw water intake for the engine, place the unit in the wet locker behind the head, discharge to starboard out of that locker. There is plenty of room for duct work thru the bottom of the head cabinet and to an output around the hanging locker.

The yard here quoated a price of 7400 for the install and a Dometic Cruisair 12K BTU, but I think i can go chepaer than that with local talent and getting a less expensive unit.

Where is Patty Ann in Daytona?

Thanks for all of the replies.

I think I have an excellent idea how the install would look. Now I just need to see how badly I need it..

FirstSightPS31 question for bjung:

How does the ductwork travel through the boat? Where are the intakes and outputs located?

My reply is a little late, but it looks like Larry already answered everything better than I could have. I could take a few pics for you for better visualization, let me know.

lsbrodsky Mine was a Marine Air 16,0000. Nice unit all self contained. The seawater pump was mounted on the floor of the wet locker. There was a problem with those pumps, intenal leakage and failure, about 10 years ago. However, the replacement was still going strong when I sold the boat.

I think Larry is right on that. When installing our cabin heater, I ran the propane line back through there and it seemed to me there was a fair bit of dead space outboard/under the drawers and under the counter behind the sink. I think it would be feasible to put a flexible duct through there.

P.S. A prior post indicated it was a 16000 btu unit.

Also, how many BTU, and what make, did the factory install?

Thanks........If I tried this as a retrofit I guess the difficulty would be running the duct outboard of the head.

lsbrodsky I can answer that as it is Asylum. The air intake is on the stbd bulkhead of the aft berth. The discharge is a duct that runsoutbd the head into the hanging locker fwd of the head. Then a grill was installed on the top of that and blows out into the main cabin. It puts out more than enough air to cool the whole boat. A wood elongated box was installed in the cabin hanging locker to act as the duct and it did remove some of the locker capacity, but only inboard. The outbd portion of the locker was unaffected. This was a factory install and nicely done.
