Awhile ago I was cleaning the garage and came upon my old divers snorkel.

I was just about to toss it when I looked at the mechanism on the very bottom of the purger.

Instantly, I thought of my Tsunami's scupper problem ( currently I use nothing, or the Vortex ).

The way the purge of a snorkel works is very effective as a one way valve ! I don't have the time to design something, ( this and my DIY (2) stroke gas trimmer / drink mixer are back-burner items ) but maybe someone can take the idea and make it work. The flexible scuba material makes a perfect seal. And, if a larger pc of that material could be had, then a larger scupper hole could be installed ( which these boats desperately need )

Just an idea...
