Described, in general, is an apparatus and related methods for removing debris from the leading edge of drive shaft housing of a sailboat. In a preferred embodiment, the apparatus comprises: a sleeve in the shape of a leading edge of a drive shaft housing, the sleeve featuring first and second line guides; a blade track along said first line guide; a first section of line; a second section of line; and a slug with a blade; wherein first and second lines are spliced with the slug and positioned in the two line guides so that (a) the slug is in the first line guide with the blade exposed at the line track and (b) pulling the first or second line guide moves the slug within the first line guide and the blade along the blade track. In a preferred mode of operation, the sleeve may be installed at the leading edge of a drive shaft housing of a sail boat, the lines run through the hull, through the motor mount inside the boat and too the upper surface, whereby manipulating the unspliced ends of either the first or second lines results in movement of the blade along the blade track. |
