I did just find a PDF copy of the manual, on the Dometic site. Looks to have been scanned from paper, likely sometime after Dometic acquired Marine Air. Looks like it does show a bit more than I remembered about the AC units itself. Probably same info as what's on the link given above, but at least it's PDF.

I think ours functions down to 42°F water temps, but I can't just now find the ref that makes me think that.

In any case, it should work just fine at 50°F water temps; that's what ours was at over this last weekend, and the boat was toasty.
