Abstract
A propeller attached to an output shaft of a boat motor is provided. The propeller may have a plurality of blades which define a leading edge. The leading edge may define leading edge angles which increase in a logarithmic manner from a base of the blade to a tip of the blade. This allows the blades of the propeller to cut and shed seaweed and/or kelp off of the blades when the boat is maneuvered into waters containing seaweed and/or kelp. Additionally, boats that employ the propeller of the present invention are quieter compared to boats that utilize prior art propellers.
