It is designed for inflatables, smaller tenders, and jon boats that run engines too small for Stingray's larger hydrofoil models. The high-tech wing shape directs water flow over its surface to generate the right amount of lift for a small engine, helping the boat get on plane quicker and stay on plane at lower speeds.\u003c\/p\u003e\u003cp\u003eBeyond lift, the wings on the Stingray Junior also stabilize the boat side-to-side, cutting down on rocking. This reduces chinewalking, porpoising, cavitation, and ventilation, which in turn improves fuel economy, control, and overall ride quality. It also increases visibility at low speeds, which adds a margin of safety.\u003c\/p\u003e\u003cp\u003eThe Stingray Junior comes pre-assembled as a single black unit and includes all mounting hardware: four bolts, four self-locking nuts, and four rubber washers. Installation requires drilling four holes through the cavitation plate, using the pre-drilled holes in the hydrofoil as a guide. For boats with narrower cavitation plates, the hydrofoil can be separated into two pieces at a rear screw and shortened in 1\/4 inch increments on each side to achieve a proper fit; both sides must be cut the same number of times.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Stingray Hydrofoils\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e JR2-1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHP Range:\u003c\/strong\u003e 9.9 to 40 HP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLift Level:\u003c\/strong\u003e Average\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Polypropylene (PP)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 18 inches long x 16 inches wide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 1.75 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation Type:\u003c\/strong\u003e 4-Hole Drill Installation\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Hardware:\u003c\/strong\u003e 4 bolts, 4 self-locking nuts, 4 rubber washers\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdjustable Width:\u003c\/strong\u003e Yes, in 1\/4 inch increments per side\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 096144006206\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat engine sizes does the Stingray Junior Hydrofoil fit?\u003c\/strong\u003e The Stingray Junior Hydrofoil (JR2-1) is designed for outboard and outdrive engines from 9.9 to 40 HP, making it suited to inflatables, smaller tenders, and jon boats.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the JR2-1 hydrofoil black or another color?\u003c\/strong\u003e This Stingray Junior Hydrofoil is black.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow is the Stingray Junior Hydrofoil installed?\u003c\/strong\u003e Installation requires drilling four 1\/4 inch holes through the cavitation plate, using the pre-drilled holes in the JR2-1 hydrofoil as a guide, then bolting it on with the included four bolts, four self-locking nuts, and four rubber washers.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the Stingray Junior Hydrofoil come with mounting hardware?\u003c\/strong\u003e Yes, the JR2-1 includes four bolts, four self-locking nuts, and four rubber washers, so no separate hardware purchase is needed.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan the hydrofoil be resized for a smaller cavitation plate?\u003c\/strong\u003e The Stingray Junior can be separated into two pieces at a rear screw and shortened in 1\/4 inch increments to better fit smaller cavitation plate widths; both pieces should be cut the same number of times for a proper fit.
