A method and an assembly are provided for mounting a pair of hydrofoils to an outboard engine without drilling holes or otherwise defacing the anticavitation plate of the engine. The assembly includes a mounting plate, an adaptor, and a pair of hydrofoils. The hydrofoils are mountable to the outer edge portions of the mounting plate. In use, the counter-rotation tab of the engine is removed and then replaced by the adaptor. The mounting plate, if not already secured to the adaptor, is coupled to the adaptor. The hydrofoils are then mounted to the opposing edges of the mounting plate. A pair of reinforcing brackets may be secured to the mounting plate such that they extend over the edge portions of the cavitation plate. The forces generated upon the mounting plate will accordingly be distributed to the anti-cavitation plate as well as the adaptor. The hydrofoils employed in the assembly preferably include rudders, which obviate the need for the counter-rotation tab replaced by the adaptor.

A hydrofoil for watercraft is provided. The hydrofoil includes a generally flat body including an upwardly extending wing for providing low speed torque control and rudders extending from the bottom surface of the body to provide high speed torque control. The hydrofoil is adapted for mounting to an anti-cavitation plate. The depth of the hydrofoil can be controlled through the use of shims or a bracket including an offset arm to which the hydrofoil is mounted. The angular position of the hydrofoil is adjustable in the horizontal plane, thereby allowing the rudders to compensate for the lateral torque produced by a propeller.
