Stingray Hydrofoils

Torque Equalizer attaches to any Sting Ray and Sting Ray Junior Hydrofoil Stabilizer to neutralize propeller steering torque. Performs like miniature rudders helping boat track straight & minimizing propeller's natural pull to the right. Reduces steering effort for the driver.

All boats react to propeller rotation causing a dangerous pull to one direction of the other. Fighting it can be very tiring to the boat’s driver. StingRay provides the solution with Torque Equalizers.

StingRay Torque Equalizers, when placed on a StingRay Classic Senior or Junior, will reduce or completely eliminate dangerous steering torque on all boats. With a StingRay Hydrofoil Stabilizer and Torque Equalizers, boats track straight, are easier to control, safer to handle, and the driver’s arm won’t tire out after a day on the water.

By adjusting in 10 degree increments on the underside of the wings, Torque Equalizers provide superior leverage over auxiliary wedges or center mounted sacrificial anode torque tabs. In comparison, other solutions don’t work nearly as well.

After one ride you’ll know why Torque Equalizers are the premier solution for correcting bothersome steering torque.

How to Install a Stringray Junior Hydrofoil

WARNING: WITH ALL ENGINE INSTALLATIONS, ENSURE BOAT ENGINE IS OFF, KILL SWITCH IS DISENGAGED, AND GEAR SHIFT IS IN NEUTRAL POSITION.

The StingRay Classic Junior can be reduced in width to provide a better fit to smaller cavitation plates. To reduce the hydrofoil width, use a Phillips screwdriver to remove the screw in the back of the hydrofoil, separating the StingRay Classic Junior into two parts. The hydrofoil is designed to be shortened in ¼ inch increments. Both pieces should be cut the same amount of times to ensure the proper fit. After the width is reduced, use a Phillips screwdriver to reattach both pieces together with the included screw.

*Not all StingRay Classic Juniors need to be cut and reduced in width. This process is only necessary for boats with smaller cavitation plate widths.

Make sure all installation hardware installation hardware is included: four (4) bolts, four (4) self-locking nuts, and four (4) rubber washers.

Place the StingRay Classic Junior on cavitation plate as far forward as possible while keeping the underside of the hydrofoil flush with the cavitation plate.

Drill four (4) quarter-inch holes in the cavitation plate on the lower drive unit and bolt the StingRay on.

The pre-drilled holes in the StingRay serve as a guide for drilling the four holes.

After drilling the four holes, remove the hydrofoil and place the four (4) rubber washers around the pre-drilled holes on the underneath side of the hydrofoil.

With all four (4) rubber washers attached, place the StingRay Classic Junior back onto the cavitation plate and line up with the four (4) drilled holes from step 3.

Place the four (4) self-locking nuts in the pre-drilled holes in the StingRay Classic Junior. The white side of the nuts should be facing upwards.

Insert the four (4) bolts from the bottom up, with the shorter bolts inserted in the two holes in the front of the hydrofoil.

Use a Phillips screwdriver to tighten the bolts. In a matter of minutes you’re ready to enjoy unmatched performance!
