ABSTRACT:
A hydrofoil for mounting on the lower unit of a marine outboard engine/marine outdrive which improves the performance and stability of a boat driven by the lower unit. Each hydrofoil includes an upwardly angled wing segment and a wingtip fin at the outer end of the wing segment. The hydrofoils are preferably mounted in a pair on the lower unit and form a V-shaped assembly. Alternately, the hydrofoils may be formed as a single unit in which they are joined near their trailing edges. When mounted on the lower unit on a boat with a V-shaped hull bottom, the hydrofoil assembly generally matches the hull bottom shape to lower drag and water resistance during operation and to prevent interference with the forks of a fork lift truck when the boat is lifted.
