  • The original hydrofoil developed by an aeronautical engineer to improve overall performance on all boats with outboard motors or outdrive units.
  • Molded 2 piece construction guaranteed unbreakable.
  • The positive effects include greater stability, consistent planing at lower RPM, faster out-of-the-hole performance, steadier turns, higher top-end speeds, better fuel economy and lower bow rise at all speeds.
  • Attaches to the cavitation plate: slides on then you drill holes to attach.
