Yes below water line. There is a cut out like a pocket under hull the tabs are tucked in probably for trim tab ram. Trim tabs are set back because of euro transom. There are some type of drains in there also.Below the water line? Possibly for a raw water washdown/livewell/etc.
I found what they go to. Motor splash well has 4 drains 2 go out back of transom and 2 for some reason go out the bottom of boat next to trim tabs. Never really paid attention to them as they are hidden. Was in bit of panic, headed out in morning and they don’t look great and are plastic. Dumb design I’m getting rid of them glassing it in.Here's a picture of the same year, make and model boat as what you've got. Are you referring to the black/white plastic drain to the right of the motor? If so, to me it looks like it could be a motor well drain? I wouldn't think that just looking at the position of the drain plug, that it would be underneath the waterline.
Not sure that I'd fiberglass them in, but a lot of the guys on here will upgrade from the cheap plastic to getting something that's stainless steel or similar.I found what they go to.

Thasnk for the pictures. If they are nylon, that's a no-no for under the waterline. Grady shouldn't have done that. However, if they are Marelon (a very special, fiber-inforced plastic), then they are totally OK. Marelon IS allowed below the waterline and is actually an excellent product.The two on the transom are obvious.
The left one connects to the top of the trim tab pocket in the Eurotransom.
