My new boat comes with a suction type head and uses fresh water to flush. I do not want to flush with freshwater so I need to install a raw water pump. I plan to Tee the pump into the AC raw water line after it's filter (has a very large filter) but before the AC pump ( will rarely be running the AC once I get my projects done and can get off this dock).

-- Will turn the pump on with a switch at the head, so no need for internal pressure switch.
-- needs to handle salt water of course, but filtered so don't think diaphragm pump is required.
-- would be nice if self priming.
-- run on 12 volts
-- very little distance and head (may even be below water line).
-- nice if quiet....the flushing pump is very quiet.

What exactly is the brand/model of your toilet? Based on your description of it as a "suction" toilet, it could be a Lavac or a VacuFlush. It matters because one is an electric fresh water toilet that CAN be plumbed to use sea water and the other is a sea water toilet available as both manual and electric version that a PO may have connected to fresh water but shouldn't have.
