A cutting apparatus for cutting debris from a propeller includes a spool securable to the propeller or a propeller shaft so as to rotate with the propeller. The cutting apparatus further includes a cutter oriented to pare debris from the spool. In use, debris snagged by the propeller is wound onto the spool, whereupon the debris is cut away from the spool by the cutter.
