Does your wakeboat have this???

So, I got underneath the boat at the carwash the other day to scrub, and I notice this spot on the underside of the hull that I've never noticed.

Its on the port (passenger) side, its just about in the center of the boat length wise, and a little in front of one of the thru-hull fittings. Its about the size of a half-dollar coin.

It appears to me like a piece of plastic or fiberglass.


What is this??? Can you check your boat, does it have this????










Thanks in advance for looking and if anyone can identify what this is!
