We're looking for the trash fence

Last night after about 2.5 hours in the sewer I finished mounting the Spectra Capehorn Extreme membrane and clark pump unit. The unit is mounted on a piece of 3/4" marine grade plywood with 1/4"-20 machine screws and tee-nuts on the back, or in this case the top of the board. I took the unit into the sewer and propped it up on tupperware containers to get it roughly into place. As I laid on my side in the sewer I marked the final location.

The board itself is mounted to two cross-beams supporting the salon floor. I originally had planned to mark the location, pull the unit out, remove the board, then mount the board alone and then screw the unit back to the board. As I had everything in place, I realized getting to the machine screws was going to be a lot harder than getting to the lag bolts so I decided to mount it en masse, with the unit attached to the board.

Putting in the aft bolts (the ones you see in the pic) was fairly easy as the sewer is deep and there is a decent amount of room between the rear edge of the watermaker and the refrigerator compressor which sits aft (and out of frame) of the watermaker. Because the sewer is not as deep as you go forward and the mast and maststep impede access, the forward lag bolts are not as easy to reach. Given the impinged space I was only able to get 5 bolts into the board. The forward outer most corner is not bolted. However, the frame of the unit is wedged between the joists and the hull so it's not going anywhere and there is not room for it to wiggle.

I have some concerns that the fact the unit is wedged will cause a lot of noise to be transferred to the boat, but I won't know about that until we turn it on. If it needs to be moved I think the only option will be to angle it more or to find a completely different location. Hopefully it will be fine where it is.

This project isn't done yet, but this was a big step. The membrane is about 40" long and it either takes up an entire settee or the entire workbench in the aft cabin, so just getting it out of the way makes the boat tremendously more pleasurable to liveaboard especially since the other settee is covered with the contents of the hanging locker where all the pumps and controls for the watermaker are installed.

Next steps are to finish all the plumbing and then setup a test run with Emerald Harbor Marine who will come out and look things over before we power it on for the first time. Sooo clooooose to done... ;-)
