Gemlux Thruhull Duckbill Scupper

[joshmon71]

I have the exact setup as Capt Chuck. same gemlux flapper same hole locale. deck not raised, armstrong bracket full float type not the skinny minny (made for twins with a single i think). cut that hole height exactly like Chuck. if was me, id move the hole cut in earlier pic to what chuck pic has. drain out transom gravity works nicer.

now with a 200lb guy in the corner a little water. fill the livewell tank behind the leaning post, same dude in corner, yeah water comes in corner a bit more. the key is it self drains at rest.

personally draining into the bilge for the deck is a no go. i have dual pumps, and occasionally can get clogged when scales get in there or a piece of potter putty knocks loose. then its a battery question when pump runs, and how long pump will run... and say a rain storm hits and boats on a mooring...for me its peace of mind i want to know that self bails at rest is all.

i may grab a duck scupper just to see, its cheap. not sure the effort to get out my existing gemlux flapper scapper is worth it, but for 15 bucks why not look.
