Unidentified floating object stumps museum

[Still Waters]

A Dutch museum devoted to beachcombing, of all things, recently  discovered an odd object in their archive that has left them scratching  their heads. According to a local media report,  officials at the delightfully-named Strandvondstenmuseum, which roughly  translates to 'Beachfinds Museum,' found the puzzling piece in a  storage area among more easily-identifiable pieces of fishing equipment  as part of what is believed to have been a collection that had been  donated to the facility.

Looks like a part that came off a trolling motor.
