Package Contents

• 1 x Hydrofoil stabilizer (FO2001)
• 4 x Sets of stainless steel screws and nuts

Installation Guide

Follow these steps for a secure installation. Ensure the engine is off and the boat is safely trailered or secured.

1. Position the Hydrofoil: Place the two hydrofoil pieces on each side of the anti-ventilation plate on your outboard's lower unit.
2. Check Alignment: Adjust the hydrofoil so it is centered and sits level on the plate. Ensure it does not interfere with the propeller's movement.
3. Mark Holes: With the hydrofoil held firmly in place, use a marker to mark the four drill points through the mounting holes.
4. Drill the Holes: Remove the hydrofoil. Using the included 6.5mm drill bit, carefully drill the four marked holes through the anti-ventilation plate.
5. Mount the Hydrofoil: Re-position the hydrofoil pieces and align them with the drilled holes.
6. Secure the Hardware: Insert the stainless steel screws from the top and fasten them securely with the nuts from the bottom. Tighten until snug, being careful not to overtighten and crack the plate or hydrofoil.
7. Final Check: Once installed, confirm that the hydrofoil is rigid and does not wobble. Re-check for propeller clearance.

Troubleshooting & FAQ

Q: How do I know if this hydrofoil will fit my motor?
A: This hydrofoil has a universal design that fits most outboard and sterndrive motors from 5 to 150 HP. To confirm fit, check that your motor has an anti-ventilation plate wide enough for mounting and that the part is listed as compatible with your brand in our table.

Q: What is the benefit of the flexible design?
A: The flexible PA66 plastic allows each side of the foil to flex independently. This feature helps absorb shock from wave impacts, reduces stress on the transom, and contributes to a smoother, more stable ride compared to rigid designs.

Q: How difficult is the installation?
A: Installation is straightforward for those with basic mechanical skills. It is a bolt-on process that requires drilling four holes in your engine's anti-ventilation plate. All necessary stainless steel mounting hardware and a drill bit are included.

Q: Is this a replacement for an OEM part?
A: This is an aftermarket accessory designed to improve performance on engines that may not have a factory-installed hydrofoil. It also serves as a direct replacement for similar aftermarket stabilizers like the NorthBoat HS001 and Davis 440 Doel-Fin.
