The StingRay Hydrofoil Stabilizer applies the laws of physics to provide the extra performance every boat needs. It's aerodynamic design creates a higher water pressure on the underside of the hydrofoil surface, which creates lift to bring the stern up and force the bow down. No other product improves performance so dramatically. Unlike other so called foils, the StingRay keeps on improving performance once the boat is up and running. In addition to providing a superior hole shot, the StingRayTM lets the boat cruise at lower speeds, stops porpoising, eliminates chinewalking, stabilizes handling, increases top end speed and improves fuel economy Installation is Quick and Easy. The StingRay Hydrofoil Stabilizer easy to install. All the hardware you need is included: four bolts, four self-locking nuts, four stainless steel washers, and four rubber washers. Simply drill four (4) quarter-inch holes in the cavitation plate on the lower drive unit and bolt the StingRay on. Pre-drilled holes in the StingRayTM serve as a guide for drilling the four holes. Placing the StingRayTM on top of the cavitation plate, insert the bolts from the bottom up. Place the rubber washers on the bottom side and the stainless steel washers between the top of the unit and the self-locking nuts. Use a socket wrench to tighten the nuts. Fits most outboards & sterndrives 25 to unlimited hp.
