Agreed Joe. It is far better to plumber it through the bilge and out
the back and loose some efficiency than go under.
But if a guy is heading down that path I feel compelled to offer the
best solution I can. (And saving a hundred bucks or more on install
costs is a bonus.)
Cheers, Russ

I would never want an underwater bilge pump discharge. I know this
from waking up to knee-deep water in Rock Hall one night. Just Say
No and run it out a normal above-the-waterline fitting!

Hi Joel,
That's not a bad idea if you can fit a float type cockpit drain in
the heads basin drain. This is from a UK supply but you get the idea.

Two details of importance:
- the bilge pump goes to the large port of the Groco manifold as the
(large) primary user, the heads basin then has to go to a smaller
port and should have a screen at the basin to minimize fouling at
the manifold (shavings & other hair are very real plugging concerns
with an elbow transition to outlet.
- the bilge pump will REQUIRE a vented discharge loop to prevent
siphon when idle and the internal check valve leaks-by.
Another idea:
My toilet intake passes under the heads basin. So I teed the basin
drain into the toilet raw water supply. It works like a charm, basin
drains out the intake trough-hull and when the toilet gets used
there is good agitation to clear the basin drain.
As an added bonus, being a salt water high organics boat area,
before I leave the boat for any length of time I close toilet supply
through-hull, half fill the basin with fresh water and pump through
the toilet. When I get back and use the boat there is no sulphur
smell in initial uses of toilet, sweet :)
