<p>A propeller guard (10) including a cylindrically shaped ring (11) which includes a plurality of evenly spaced ports (36) therethrough. The ports (36) in the ring (11) are formed so as to allow water to pass therethrough during operation so as to improve the performance characteristics, specifically acceleration, planing, speed and steering, of the motor (13). The ring (11) is attached to the motor (13) by an attachment bracket (12) which is designed to inhibit fatigue and cyclical loading failure caused by vibrations of the ring (11) during use. The ring (11) is formed in a generally tapered rectangular cross section in order to minimize the drag and vibration characteristics thereof during use. The ring (11) is formed so as to be attachable to an outboard motor (13) to surround the propeller (14) thereof to protect the propeller (14) from underwater objects.</p> |
