  • Patent number: 7421771
    Abstract: A tool comprising a handle, a shaft, and a pair of spaced-apart projections for use in removing the propeller from a watercraft. The projections are generally arranged at a distal end of the shaft so as to extend therefrom in a generally perpendicular direction. The projections may be placed over the rim of a propeller hub, rim of an exhaust port, or the lower portion of the trailing edge of the propeller blade generally close to the hub. The tool is then rotated to pinch the object placed therein between the two projections. The user can then utilize the handle and the shaft to have a lever arm with which they can use the pinch point as a grip on the propeller and manually prevent the propeller from rotating while attempting to rotate a nut holding the propeller to the watercraft with their other hand.
