STINGRAY HYDROFOILS XPI Hydrofoils

The StingRay Performance System is designed to get your boat on plane faster, eliminate chinewalking and porpoising, and improve stability and fuel efficiency. The system is based on the Hydrofoil Stabilizer, now made with SPEED-XP™, an extreme performance hydrophilic material that increases the speed that can be achieved over previous models. SPEED-XP™ binds a thin layer of water to the foil, dramatically reducing hydrodynamic drag and improving overall performance. Unlike simple curved or flat planing aids, the StingRay actually creates lift, improving cornering ability. The StingRay’s ability to get on plane more quickly not only benefits waterskiers, powerboat racers and others looking for quicker acceleration, it also improves safety by keeping the bow down and improving your field of vision. StingRay is easy to install and includes all necessary hardware; the XRIII features no-drill installation.

  • Put your boat on plane faster, eliminate chinewalking and porpoising and improve stability
  • Reduce hydrodynamic drag and improve fuel efficiency and overall performance
  • Easy installation, hardware included
  • StingRay Jr. is for smaller engines (from 1 1/2-40hp)
  • StingRay Torque Equalizers minimize steering torque, improving boat control

            This hydrofoil really works! I have a small 15' boat that had issues planing and maintaining a plane at lower speeds. Also had stability issues in mild wind chop. With the hydrofoil all those problems have vanished. The boat handles perfectly and handles wind chop easily. I can trim the outboard to optimize performance in smooth water. This is a great product and installs easily. I prefer the "old school" drill holes type so this improvement was very affordable versus the clip on new styles. Good Luck and Safe Boating.

                Comments about XPI Hydrofoils:

                Im on my third boat now and I installed each and every one of my boat with this Hydrofoil. Had it on my first boat, a Bayliner 1952 with 135 HP Alpha 1, , my second boat SeaRay 215 with 260 HP Alpha 1, and now My Parker 2320 with Yamaha F250 Outboard. It will get me out of the hole much faster and allows me to plane at a lower speed. Top speed is the same tho. There is no need to use my trim tabs with these on. Just remember to drill the hole correctly, sometimes removing the prop will get you a better shot at drilling it.
                It takes me a few minutes and all of the screws rubber washer is included. Great product.

                  Very Easy Installation. Make yourself a template before drilling your holes. The improvement in performance was significant immediately. 20' V Hull boat. No trimming of the sterndrive required any longer. Boat planes quickly and effortlessly. Very inexpensive improvement. Great Product.

                    I placed this hydrofoil on a 40 hp Yamaha mounted on a 13 foot Whaler. The improvement in handling was remarkable. According to my GPS I lost about two mph on the top end, but the improvement in stability and handling was well worth it.

                    overall its the best money I could have spent...product did loosen slightly during first use because of rubber washers supplied but in no way affected results when installed on 165HP outboard
