A line cutter in the form of an apertured disk or plate mounts onto the housing of a propeller drive or screw drive. The line cutter mounts over the propeller shaft, and covers the propeller shaft seal. The line cutter opening has a small clearance over the shaft which is smaller than a standard fish line gauge, i.e., about 0.002 inches. Fishline or other debris encountered by the screw drive winds around the shaft and winds back until it is torn, ground, or cut when it encounters the circular cutting edge at the small clearance. This line cutter is useful on a trash skimmer work boat.
