The problem, as I see it, is that putting in a deck pumpout fitting means
another hole in the boat. And holes in boats are VERY BAD.

The deck core is exposed, the fitting needs to be sealed ,, and who knows

Not at all a big deal if you do the job right. Get the West System
manual and they will show you how to remove some of the deck core and
replace it with a high density filler that will prevent water from
getting into the core. Sealing the fitting is also no big deal at all.
