    I have a Post Marine Convertible and I can not find the a/c drain lines nor can I find any information for them in my manual. Can anyone help me and tell where they may be and how I can get to them to clean them out. Thanks guys. I am new to the forum so any help would be great.

    What year is your Post and what is the layout of the AC units? Where are the intake or return vents?

    Find your return a/c vents in each room. The a/c unit will not be very far from the return vents.

    I have the same boat\year. In the forward cabin, open the starboard smaller closet door. The AC unit is in the top of this cabinet and the drain line goes down the corner of the cabinet, into the bilge PVC connector tube, and into the shower sump under the galley floor.
    For the salon unit, remove the small ceiling panel above the side room upper bunk. You will see the drain hose with a "T" to the side room AC unit. This hose goes into the engine room and connects to the seawater outlet for the AC pump.

    Cleaning the actual AC drip pan is pretty much not possible. I blew backwards in the drain line and poured some water into the coil area. This gets most of the debris out.
