Designed for maximum lift, which means that the StingRay™ XR4 Senior Hydrofoil has the design strength needed to pop your boat up out of the hole quicker and smoother than ever before. Plus, with the XR4 Senior installed, you'll notice that your boat's porpoising, chine walking, cavitation, and ventilation problems will all be virtually eliminated and replaced with a safer, smoother ride. In fact, this hydrofoil's downturned wings pack the water down and around the prop to ensure that cavitation problems – especially with pontoon boats – become a thing of the past. Your water skiers, wake boarders, and tubers will notice how quickly and smoothly they go from zero to up and skimming across the water. StingRay XR4 Senior Hydrofoil also features great graphics and colors that go along with the style of most modern outboard motors. Its 2-drill installation is among the industry's quickest and most secure. Designed for maximum lift and a smoother ride. Pops boat up out of the hole quicker than ever. Reduces porpoising, chine walking, cavitation, and ventilation. Downturned wings pack water down, around the prop. Quick and easy installation. Great graphics and colors.
