Doel-Fin® Stabilizer Fins - Black
The Original Hydrofoil
Doel-Fin was developed by an aeronautical engineer to improve overall performance on all outboard motors and stern drive units from 5 horsepower and up (Volvo Penta outdrives excepted).
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.
