Bennett Marine's new Sport Tab System is designed specifically for trailered boats and the limited transom space on boats 20' - 23' in length. They provide all the benefits of traditional trim tabs - improved planing, fuel efficiency, speed, safety, and overall boat performance, as well as correction for uneven weight distribution. The bat-wing design with drop fins provides 30% more lift for its span. The taper in the trim tabs provides variable lift, a great deal of lift at slower speeds and less lift at faster speeds. The result is a trim tab system that provides precise control. Includes rocker switch. Five-year warranty.
