Black Senior XRIII Hydrofoil

The revolutionary New XRIII StingRay™ Hydrofoils apply the laws of physics to provide the extra performance every boat needs. Its 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.
Improves Thrust:  These Hydrofoils actually harness the propeller’s thrust cone. How? By converting
prop-wash that is normally thrown back and above the waterline (lost kinetic energy) back into useable thrust. No other product improves performance so dramatically.
Unlike other so called foils, the XRIII StingRay™ keeps on improving performance once the boat is up and running. In addition to providing a superior hole shot, the XRIII StingRay™ lets the boat cruise at lower speeds, can stop porpoising, and chinewalking, stabilises handling, increases top end speed and improves fuel economy. 
One piece design. 
Made in USA.
Attractive blister packaging.
Easy NO-DRILL installation takes about 5 minutes. That’s right, no holes drilled through your cavitation plate. Takes just a socket wrench and Phillips screw driver to install.
