What is this piece of plastic I vacuumed in my bilge
Hello Trawler Friends,
I keep a clean bilge and know this was not in there a few months ago. Does anyone have an idea what it is?

A backing plate from a sander? Leftover scrap from construction? A holesaw cutout?

Hi, it’s transparent plastic, approximately 1.5”. Thank you. As long as it’s not part of my bilge pump, I think I’m happy

Is your bilge pump switch an ultra safety switch or an aqualarm switch? It looks like the bottom of the transparent case that contains the float

I know it! I was curious as to what the part was too & knew if I just sat back & waited, someone would recognize it!

I’ll confirm with photographic evidence when I get back to the boat. I was thinking the same thing about forensics. If that in fact is the part, that’ll be so satisfying.

It's a "finarasis" that bleeds excess air off a horn compressor. Usually found on the fly bridge inside a brow locker.

Probably a piece from your fiberglass deck.
