StingRay Classic 2 Senior Hydrofoil

The StingRay Classic 2, Senior Hydrofoil is engineered to lift all boat types out of the hole quicker than ever before and keep boats on plane at lower speeds. Ideal for boats pulling tubers, skiers, or wake boarders the Classic 2 increases driver visibility by getting the bow of the boat down earlier. The drag-reducing wing texture ensures the boat reaches it maximum top-end speed.

The 4-Bolt Installation method is the industry’s most secure yet simple installation giving you confidence and peace of mind while on the water

Horsepower Range: 40-300

INSTALLATION STEPS:

1. Place the StingRay Classic 2, Senior Hydrofoil on top of the cavitation plate as far forward as possible while keeping the underside of the hydrofoil flush with the cavitation plate.

2. Using an Electric Drill and 1/4” Drill Bit, drill through the cavitation plate using the four holes on the top side of the hydrofoil as a guide. Make sure to keep the drill perpendicular to the cavitation plate while drilling. Be sure to drill through each of the four holes in the hydrofoil.

3. After drilling, remove the hydrofoil. Place the (4) Rubber Washers around the holes on the bottom side of the hydrofoil. These fit snugly around the raised rings surrounding each hole.

4. With all (4) Rubber Washers attached, place the hydrofoil back onto the top of the cavitation plate so that it lines up with the four drilled holes from STEP 2.

5. Place the (4) Nylon Hex Nuts into the hex pockets that surround the holes on the top side of the hydrofoil. Make sure the smaller openings on each of the Nylon Hex Nuts are facing upwards and the larger openings on the Nylon Hex Nuts are facing downwards.

6. Insert the (2) ¼-20 x 1.5” Stainless Steel Bolts (back holes) and the (2) ¼-20 x 1.0” Stainless Steel Bolts (front holes) from the bottom of the hydrofoil, through the holes that were drilled in STEP 2, up through the holes in the top side of the hydrofoil, and into the Nylon Hex Nuts.

PRO TIP: Place a finger on top of the Nylon Hex Nuts to keep them in place while inserting the Stainless Steel Bolts from the bottom side.

7. Tighten the Stainless Steel Bolts with a Phillips Head Screwdriver until the hydrofoil is secure.

8. Check for propeller clearance by slowly turning the propeller by hand making sure that there is no interference between the StingRay Classic 2, Senior Hydrofoil and the propeller before operating!
