Not Attwood, perhaps Gemlux.
You need a screen of some sort in the deck drains, unless you don't care what does doen home, like a sinker or something like that.
I bought the 1.5 in. Perko deck drains, plastic threaded, that have the cross hairs screen. Slight mod otherwise perfit fit to original. I reused the original 90 deg adapter from threaded to hose. The original deck drains did not erode, had to chiesel crack them out of there, so went back with plastic.
When I checked Gemlux catalog, the 1.5 inch stainless drains had a flange ID much bigger than originals for my boat. Not workable. But may fit in yours. The Gemlux came with built in 90 deg takeoffs for hose, which avoids the adapter, I would have gone this way.
