Now, why didn't I think of that?

It's great when someone who actually knows what they are talking about
shows up.

I just went through Calder's section on head plumbing and it sounds
like a lot of the greater odor of salt water flush over fresh is not
the salt but all the plant and animal stuff that comes in. A strainer
in the intake line sounds important.

There's a much easier way. Tee the head sink drain into the head
intake line. To flush the sea water out of the head intake line--the
whole syststm, in fact--close the head intake seacock...fill the
sink with clean fresh water...flush the toilet. Because the seacock
is closed, the toilet will pull the water out of the sink. In fact,
if you have the fresh water to spare, you could just keep the intake
seacock closed and use this method to flush the toilet all the time.
