Ideas?

I thought of getting a dedicated wet vac, and putting a through the hull
fitting on it that would drain the water out of the tank, putting a 90 ball
valve on there, and opening it when the tank got close to full.

Ideas?

Why do you need to pump out this pipe?

Can you use a cap with a hose fitting and let it fill to capacity and
then drain out on it's own?

You'd need to "permanently" install the 200' of hose (or PVC pipe) but
you'd be one and done instead of "occasionally" having to set up your
pump system for short term use.
