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 2 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, steadier turns, higher top-end speeds and lower bow rise at all speeds.
• Doel-Fin® improves overall performance - even on boats with well designed hulls • Save up to 30% on fuel comsumption • Faster out-of-the-hole for happier water skiers • Maintain lower planing speeds without constant throttle adjustment
for wakeboarding, tubing or beginner skiers • Less bow rise for better visibility and increased safety • Simple 15-minute installation; hardware included

Once you’re on plane, most of the Attwood Hydro-Stabilizer is out of the water. Drag is reduced resulting in higher speed.
Ordinary, flat hydrofoils ride on or below the surface of the water, causing speed robbing drag.
* Will not fit Volvo Penta 280/290 outdrives and BMW drives however, it will fit Volvo Penta 270 outdrive ** Will not fit Mariner 20 HP engines where the cavitational plate is too small for installation
