Doel-Fin Black Hydrofoil usually available 2-5 business days upon ordering.

Doel-Fin Stabilizer/Hydrofoil Fin, black


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, 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.

The Volvo 280 and 290 outdrives use the Volvo adapter kit #445.

The Volvo 280DP and 290DP (duo-prop) outdrives use the #446 adapter kit
