StingRay Stinger Hydrofoil, installation on I/O, non drill method.

Use the screws with the blue locktight on then when follow non drill method....The StingRay Stinger Hydrofoil is designed specifically for speed and versatility. Its contoured delta-wing profile reduces drag, while the extended tips deliver increased stabilization. This Stingray hydrofoil was designed with a patented No-Drill Technology that allows for installation on a wide range of engines; anywhere from 40hp to 300hp. It requires just two set screws to attach to your craft. Smaller engines with less horsepower still reap the benefits of this device by using only half the drill holes other designs require on a tough-to-plane boat. This black hydrofoil stabilizer is one of the fastest in the industry, and improves both the speed and function of your craft. It comes complete with the necessary hardware for bolt-on installation. Plane faster, eliminate chine walking, wipe out cavitation, stop porpoising and experience a swifter, smoother ride with this particular hydrofoil.
