    Can anyone help me with finding out where my ac manifold is located? Any ideas would be greatly appreciated.

    Can you rephrase the question? Are you saying air cond. manifold?

    Not sure what happened, I replied yesterday am. You don't have a manifold. The AC water enters the cabin under the salon couch (rear center). Remove cushion and rear wood panel. You will find a T fitting, which separates port and starboard run. Pull hoses off fittings, connect dock water hose, you will need 2 connectors 1/2 " and 3/4 ". Turn dock water on, let run about half hour, you will not believe the crap that will blow out. If you still don't get a good flow to the forward AC, there is another T under guest room lower bed. You should also check the hoses from the thru hull fitting all the way to the first T. I get growth in those lines also. We run our AC 24/7, I have to do this every 2 or 3 weeks in the summer.
