Thanks for your input.
I know that there is only one intake in the bilge; so after your
advice, I will now set about to re-plumb them separately. I still
may feed them to one thru-hull, however. I would envision making
up a fitting from a "Y" where the single line is connected to the
thru-hull and the two arms of the "Y" are connected to the separate
pumps right at the thru-hull.
Anyone see any problem with that idea?
My bilge sump only holds about 2 gallons of water, if that, so I may
have a space is fitting two pickups in the bilge.......we'll see.
Thanks again for your help,

Hello Ron
It sounds like every boat is different so far.
I've got two pumps, one inside and one in the cockpit. They are
plumbed separately, so two pickups in the bilge and two through-hulls.
The only thing about your setup that might worry me is that a
failure in one pump might defeat the use of the other - the water
could leak back through. But would it worry me enough that I'd
install another through-hull fitting? Depends where I'm going with
the boat.
To your question, air doesn't suck in from the other pump when not
in use because the pump will act like a one way valve.
If I were you I would verify what is going on in the bilge though,
I would hope there are two intakes.

Watching the thread on bilge pumps, I have a related question.
My '77 38MKII has two Whale Gusher manual pumps; one mounted next
to the galley foot pump and one mounted in the side of the port
cockpit coaming between the seat and the rear corner seat.
There is only one exit for both pumps????? It used to be hooked
up when i bought the boat in 1977, however, after several interior
changes and a re-powering project with a saildrive unit 5 years
ago, the original hoses don't make sense.
Do both pumps actually pull on one suction hose from the bilge?
Why doesn't air suck in from the other pump when not in use?
Does anyone else have this arrangement and can you give me a
simple description of how the plumbing goes for these two pumps.
There is a "y" fitting along side the motor???which seems to run
to the thru- hull fitting.
Sorry if this sounds confusing, but I"m confused now as well.
Thanks, Ron Casciato
