Had to change the ones out of my boat. And these worked great.

Diagram shown screw holes top bottom left right but the scuppers I received have diagonal holes. I had to rotate the scupper 45 to make screws line up. And to top it off, they leak like crazy...

Inside diameter 1 13/16”, outside diameter 2 13/16”, the holes are on a 2 5/16” 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.

I do like the clean look they give, and they do keep most of the water out and from flowing back in, but they ste bit 100%. They need to be installed completely vertical. Any angle at all and they don't stay sealed. Also they ate subject to debris. Even a small pine needle causes them to stay open.

This product is pretty much self explanatory. It’s a plastic circle with rubber circle rings. The problem is there is holes that comes with no screws. For like $15, this thing should have came with the four tiny screws. The company is lazy. I used this as a cover for my washer drain hole. So I just used #6 drywall screws but still. It should have came with screws.

Good quality, but not for ATTWOOD scuppers used on Boston whaler. Looks like right size but not quite. So look for ATTWOOD if your OEM scupper is ATTWOOD
