Correction on the lable...it says, "remove cover when boat is in transport"...so that's a clue. I lifted the back bench seat and there a well, but not close in size to this and the seat wouldn't go back into place if I put it there.
Here are some pics.....I don't currently have one from the inside looking back.
Does not look like it came off your boat at all. Previous owner may have had it there for whatever reason and not removed it. Are they 2 vent holes in the middle of it ??? could be a stowage box or live well cover that should be removed when transporting so it does not bounce out.
Just guessing though.
It's the stuff that increases suicide rates in Canada...some call it snow..I call it little fluffs of hell.
That said, perhaps the previous owner found it floating on the water one day, and grabbed it to prevent damage to other boats. Tossed it in the engine compartment and forgot all about. Looks like a ski locker cover to me.
No idea on the cover, looks like it's from a different boat. You don't drive on the left side of the road up there do you? Maybe just parked weird. I'd look into some trailer tires. Those radial TA's are really not safe on a boat trailer. Boat looks very nice.
