Davis Instruments Doel Fin Hydrofoil

Davis Doel-Fin Boat Stabilizer Fin

Doel-Fin is the original hydrofoil developed by an aeronautical engineer to improve overall performance on all boats with outboard motors or outdrive units. Molded in two pieces of guaranteed unbreakable, high-strength plastic, each foil is designed to flex independently to absorb shock. The positive effects include greater stability, consistent planing at lower RPM, faster out-of-the hole performance, better gas mileage, steadier turns, higher top-end speeds and lower bow rise at all speeds. Doel-Fin is designed for use with small motors, big motors and inflatable dingies. Boats with small motors no longer porpoise with the bow-up when the throttle is applied, and they can achieve planing at lower engine speeds. Big motors benefit from less stern suction, faster planing times, and steadier turns. All of these features add up to increased fuel efficiency.

Fits all motors except Volvo Penta 280 and 290 outdrives.
