ABSTRACT A device mounted in encircling relation to a propeller shaft. The device cuts lines, nets and weeds, thus preventing entanglement of the propeller and preventing entanglement damage which may result to the parts of the driven assembly of the outboard, inboard/outboard or trolling motor vessels. The device includes a non-rotatable, annular cutting ring member having one or more double-edged cutting blades, that is disposed in sandwiched relation to two rotatable annular members. One of the rotatable members carries no cutting blades, and the second rotatable member carries a plurality of double-edged, circumferentially spaced blades that individually cooperate with the non-rotatable blade in a shearing action. The non-rotatable member includes a protruding, forwardly expanding, wedge member, the wedge member being configured to define a forwardly opening wedge-shaped cavity. The wedge-shaped cavity is adapted to receive, and interact with, the propeller shaft housing. The rotatably mounted annular bolt ring is disposed intermediate the non-rotatable cutting ring and the propeller shaft housing. The rotatably mounted annular cutter ring is mounted rearwardly of the non-rotatably mounted cutting ring so that the non-rotating cutter ring is disposed in sandwiched relation to the bolt ring and the rotatable cutter ring. The protruding wedge members cavity enters into abutting engagement with the propeller shaft housing attendant rotation of the propeller shaft, the propeller shaft housing entering into fine engagement with the forwardly opening wedge-shaped cavity substantially instantaneously upon the introduction of a load on the apparatus
