I don't think you have to run it overboard.  It just has to get above the
water line on all angles of heel.  I didn't install mine so it isn't a
fresh memory but I believe mine runs into the engine compartment, through
the compartment roof and into the HVAC compartment under the companion way
stairs.  I can't recall how it is terminated.

I have a PYI (PSS) dripless seal now and generally like the engineering of
PYI products but I suggest that you consider the sailor sams last drop
seal.  I was quite impressed by the display at the boat show.  Of
particular interest as I recall was that instead of a rubber bellows which
could weaken the last drop seal uses ridged hose and a spring pack.  As I
recall, the carbon rings can also be replaced without having to pull the
prop shaft.
