The StingRay XPI™ creates lift to bring the stern up and the bow down.
Its patented high-tech shape causes water to flow over its surface, thus hydrodynamically creating upward thrust pressure on the underside surface.
Upward pressure lifts the hull, resulting in less drag.
The StingRay's XPI™ wings then stabilise the water pressure, stopping porpoising and chine walking.
Improves fuel performance as much as 40%. Will fit any outboard or sterndrive 40 to unlimited HP
