Davis Doel 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.

  • Increase performance and safety
  • Increases fuel efficiency and reduce bow rise
  • Promotes fast out-of-the-hole times
  • Designed by an aeronautical engineer, Doel Fin is a true hydrofoil
  • Simple 15-minute installation, hardware included
  • Doel-Fin fits all newer outboard and stern drive motors from 5 horsepower, except Volvo Penta outdrives
  • Doel-Fin improves overall performance - even on boats with well designed hulls
  • Save up to 30% on fuel consumption
  • Faster out-of-the-hole for happier water skiers and wake boarders.
  • Maintain lower planning speeds
  • Simple 15 minute installation (hardware included)
