(first post!) I'm working on a new-to-me, 2000 Aquasport 275, and I'm having trouble identifying a replacement for the existing thru-hull anchor locker drain covers because one is missing. It's a type of clamshell cover, but is not just half the clamshell. It's a complete fitting with a small 3/4 inch tube that fits into and is just glued in a 3/4 inch hole. See the photos of the fitting I have on the port side, and the hole where a fitting is supposed to go on starboard.
Anybody have any clue what I could find as a direct replacement for this or something similar? Alternatively, would placing a 1/2 inch (which fits a 3/4 inch hole) regular straight thru hull with no clamshell be a problem here? Or would that allow a lot of water into the anchor locker in rough seas? It's probably 3 feet above the water line.
