Attwood 3876-3 Boat Self-Bailing Cockpit Mounted Scupper Valve Kit

i tried the fancy scuppers, and in the end they just don't last. i heard the ball ones can get clogged easy, are loud, and need to be at right level to work right. so i skipped trying that one. i did try the duckbill. it worked great at sealing and keeping water out. but due to the design, it didn't drain very fast. i didn't really like that. it would also clog at the littlest piece of anything. biggest problem was that it warped and deteriorated far too fast. since it's molded in a specific shape, once that shape is compromised it doesn't work very well. on this type, the flap is thick and doesn't warp very much(and is easily replaceable), it opens fully to drain at max flow, and it seals enough to keep water out. they may be low tech, but the standard flapper scupper is my preference.

Flappers get deformed over time and let water flow back into boat. These high quality replacements are very easy to install (4 screws) and are exact OEM parts. I would recommend. First photo is replaced flapper and second photo is original deformed flapper.

Good

Outside diameter 2 3/4”, the holes are 2 3/8” center to center. Ideally this would be for a scupper that measures 1 3/8” inside diameter or smaller, that is the size of the rubber “seat” that the flap will seal against. Product looked fine but returned it because it was too small for what I needed. Hopefully measurements will prevent more people from ordering just to find out the size .

Works great thanks

Been driving around for the last few years with wet feet and wet everything else that touched the floor. Just sort of ignored it but finally replaced these and now have a perfectly dry boat floor. Been so long I honestly didn’t remember these work almost perfectly to keep every bit of water from flowing back into the hull so figured I’d just have a slight improvement with a little less water sloshing around but now no water at all! Best 15 minutes of boat work I’ve done yet!

This is a direct no-drill replacement for the scuppers on my 1996 Grady White Tournament 192. I compared this to a replacement scupper direct from Grady White, and there are some small cosmetic differences. The Grady White original and OEM replacement are whiter and more opaque. This scupper is more translucent. If anything, this feels slightly higher quality than the OEM from Grady, but it's close. I couldn't find any spec on the material used in the screws, so I ordered 316 replacements to avoid rust.

Product is fine..Just know your only getting one..it is not a pair...I had to order another one...Need to specify ,normally they come in pairs...

Ottimo prodotto

Super, très bon produit. Je recommande

Worked as expected good price

No me ha gustado pense q tenia algún tipo de resorte para realizar la funcion de antiretorno solo retorna por la goma y la veo edeble y poco duradera y perdera la función d cierre pronto. De momento no puedo decir mas la monte en un bote auxiliar del barco, veremos si hace la función
