If you're going to re-plumb the head... this is what I'd recommend:
Plumb the head discharge into the holding tank. Then add a diverter valve to the holding-tank's pumpout line. Have one side go to the pumpout fitting on deck, and have the other go to manual diaphragm pump, like a Whale Mk V, and then to the seacock and through hull. This allows you the ability to dump the holding tank when out past the three-mile limit and minimizes the number of hoses and the length of hose needed for the system. Simplicity is a good thing when it comes to the head plumbing.
Another common modification, if your head sink drains through a through-hull with a seacock that is below the waterline, is to add a t-fitting and have the head's water intake come from the head sink drain line. This allows you to flush the head with freshwater or saltwater. To flush with saltwater, plug the sink drain and open the seacock. To flush with fresh water, close the seacock and fill the sink with water. This makes winterizing the head very simple.
While this is a pretty good place for general information, you might want to check the Oday sailors forum at Sailboatowners.com as well as the various O'Day specific websites.

I don't yet know whether the flush water is coming from a throughhull connection or not, but at least I know what to be looking for now.
Haven't tried drikning the water yet--maybe I'll just go ahead and shock the system first to be safe!
Thanks for the system description, SailingDog!
One more followup question, other than these boards, is there a good source for info on this specific model? I could have a million questions, and not sure if this is the right place to post repeated questions (a different Sailnet forum, or this one?) Books, catalogs, etc.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.
