Installation:

XPI and XPII Installation is Quick and Easy.

Both the StingRay™ XPI and XPII Hydrofoil Stabilizers and StingRay Junior™ models are 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 StingRay™ serve as a guide for drilling the four holes. Placing the StingRay™ 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.

In a matter of minutes you’re ready to enjoy unmatched performance.
