The clear plastic part sight glass part is where the restriction part comes in with USCG.

Supposed to be above deck with inboard engines. Below deck with outboards.

With all metal separators it does not matter ehre mounted.

Although I've seen 100's of plastic see thru separatros mounted in the splashwell next to the O/B.

The plastic bowl drain is useless if you can't get to it, or put a drain cup under it. Go figure. YOu'd dont want some to stand on it, but you don't want it buried and useless either.
