US Patent:
7270584, Sep 18, 2007
Filed:
Mar 2, 2006
Appl. No.:
11/366703
Inventors:
Mark Judd Mitchell - Cowdrey CO, US
International Classification:
B63H 5/16
US Classification:
440 71
Abstract:
Disclosed is a device that protects inboard/outboard motors (up to 250 horsepower) from damage and simultaneously provides an underwater hydrofoil that both helps prevent inboard/outboard motor damage and is specifically designed to improve the efficiency of an outboard motor and the speed and ride of a boat. In one embodiment, an underwater hydrofoil, skeg enclosure, skeg protector and lower-unit protector are combined into a single unit that protects the skeg, the propeller and the lower unit of an inboard/outboard motor while simultaneously improving the efficiency of an inboard/outboard motor and the speed and riding qualities of a boat using that inboard/outboard motor.
