Spent a second day contortioning in the aft berth of Lady Kay. Have installed shore power receptacle next to the outboard, made a cutout for the AC distribution panel next to the DC panel and roughed in all wiring to supply AC, outlets and battery charger. I am planning to put the outlet in the galley cabinet. Couldn't find my way sraight down there though. The stainless tube holds the gas line, and there was not enough room for an electrical wire. There is no room between the liner and the hull. I finally ended up going back to the aft area, and through my (now enlarged) drain hole mod under the aft berth over the ballast tank to the galley cabinet. A little extra wire, but it worked.

I've fabricated a U-shaped shelf that stradles the battery box, which by the way was installed so crooked that I think that the $6.00/hr yo-yo that did it threw it in place from 6 feet away.... Anyway, the shelf will hold the Marine Air 5200 Reverse Cycle AC unit, electrical control box for same, and the battery charger. Under the access door to what little bilge the WB has I've fabricated a shelf that holds the cooling water pump and strainer. Both shelves have been epoxied on the back, and are still to be glassed in place. I installed the through hulls for the cooling water intake and exhaust. The intake is solid brass with a nice brass ballcock shutoff. I must say that the installation kit Marine Air sent me is complete, and with decent quality materials. The instruction manual is very well written, and most helpfull. So far I am impressed with them.

This is a big project, especially if you want to do it right. I shudder to think what a yard would charge. Plus, they wouldn't care as much as I do, and that always shows. Still I feel it's worth doing.

I'm taking pictures along the way. At the end I'll do a comprehensive report for Tech Section/Mainsheet...stay tuned

It's done.....THIS IS NOT A SMALL JOB......It took longer than I thought it would, but it came out very well. As mentioned I will produce a comprehensive report. Here's a few pictures though.

As mentioned before, and as is known to those who have tried, snaking anything on the 250 is a challenge, especially something as large as 4" ducting. Also, throughout this entire project my aim was not to use space that was otherwise in use. Delivering the conditioned air forward is thus difficult. Let me say that the "squirrel fan" on the Mermaid M-5200 houses one big mean squirrel. This thing puts out serious airflow. So after some testing I decided that one register, which is adjustable for direction btw, next to the companion way steps, aimed into the cabin is more than adequate.Standard the unit comes with flexible hose for ducting. With people contorting around in the MRI chamber, this stuff would get damaged quickly. So I opted for 4"pvc thinwall pipe. If you look carefully on the picture you will see a "T" that shoots down into the aft berth area, again with a directional register so you can aim it at the wall and let it diffuse, instead of freeze your face. The whole setup blends in quite nicely with the surroundings, takes up little otherwise usable space and is most effective.

Finally, here's a shot of the cooling intake, strainer and pump. As the pump is not self priming and has to be below sea level, there is really only one place to put this.

Lady K. Is pleased. I'm looking forward to enjoying this setup.

Impressive Oscar. I am continuously amazed at the ingenuity and craftsmanship of sailors. I hope to be able to do the same types of things on my boat.
