Without StingRay

With StingRay

Eliminates Chinewalking

By their very design, "V" bottom boats are susceptible to chinewalking.
This dangerous side-to-side rocking lessens control and performance.

Again the StingRays wings go to work.
The stabilizing action balances the boat to keep it upright and moving forward without a hassel.

StingRay XRII works while you play.


Eliminates Porpoising

Porpoising is the name given to the forward and back motion some boats make while riding on the water. Picture a porpoise leaping through the water and you get the idea.
It may be fine for them, but its murder on a boat's performance, comfort and safety.
This pounding causes many people to ride only in the very back of the boat.
After all, who wants to get bounced around all day?

StingRay corrects this action, providing you with more comfort, safety and performance.

Quick and easy installation all the hardware you need is included: four bolts, four self-locking nuts, 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 the top of the cavitation plate insert the bolts from the bottom up.
Place the rubber washers on the bottom side.
Use a phillips screwdriver to tighten the bolts.
In a matter of minutes your ready to enjoy unmatched performance.
