This fin will help improve overall performance on all boats with Outboard Motors or Outdrive Units. Even on boats with well-designed hulls this can help improve performance by providing stern lift which compensates for motor weight. It can also help decrease fuel consumption by as much as 30%. This Hydrofoil fin gives you faster out-of-the-hole performance for better water skiing along with reater stability, steadier turns and higher top-end speeds. At the same time, it allows for consistent planning at lower speeds for wakeboarding, tubing and beginning waterskiers. The lower bow rise at all speeds means better visibility and increased safety. Doel-Fin is designed for use with small and large motors, as well as inflatable dinghies. It is molded in two pieces of guaranteed unbreakable, high-strength plastic; each foil is designed to flex independently to absorb shock. It is a simple 15 minute installation and all hardware included. White in color. (Picture does not show actual color of product.)
