 The stateroom Mermaid Marine Air 5200 btu AC\Heat got some work done on it. I We had a little time and wanted to do something that we did not need to tear up the boat to do. This fit the bill. This really would not take all that much time to do but we just do not have all that much time considering all the projects.

  We started with the March LC-3CP-MD pump. It and the Sherwood Sea strainer should be on an incline towards the AC unit. This is to prevent air locks. Of course like everything else this meant engineering the system. This is a system in itself.

 We left enough room at the top of the March pump for some sound insulation under the floor board hatch if we decide we want some later for noise dampening.

You can imagine wanting to turn on the AC after being in the heat all day and it not working because of an air lock. Then spending time while dripping sweat trying to bleed the system. This prevents that.

 So we first tried mounting the pump by drilling the top hole and screwing in the screw. No deal as the bottom screw is barley visible and the hole cannot be drilled after the fact. No access. So the top hole had to or we decide to fill with the easiest thing at hand 3M 4000 UV so water would not penetrate the rib of the boat in the hole. The marked a hole for the bottom screw and drilled it in. Mounted the bottom and then was able to drill the top hole and get it mounted. There is a110 volt 10/3 wire coming off that we snaked to the hanging locker.

The bronze hose fitting will come out. We use plastic to plastic and bronze to bronze fittings if at all possible.

 The shower sump is the yellow piece, we had to move it.

 We then chose a little lower location for the strainer where we would have access to clean it and drilled the holes for the mounting bracket.

 As a side note this through hull and valve we may decide to try to also use for the anchor wash down pump. And that pump could also be used for a stern wash down. We may not get the stern wash down completed before we leave but we can get it setup for one.

 This means installing a “T” on the through hull valve for later use.

 Now the basic little system is in place and the real plumbing is ready to be installed here.

 We stopped at Marine Exchange and picked up some more plastic fitting (for the plastic pump and strainer fittings) and some ¾ inch water hose for these connections. Now to plumber tape them up and heat gun the hose to fit it all together.
