Position the Hydrofoil: Place the two halves of the hydrofoil on each side of the engine's anti-cavitation plate. Ensure it is centered and level.

-
Drill the Holes: Remove the hydrofoil. Carefully drill the marked holes through the anti-cavitation plate using the included drill bit.
-
Mount the Hydrofoil: Re-position the hydrofoil halves. Insert the screws with washers through the top piece, the cavitation plate, and the bottom piece.

Secure the Hardware: Attach the remaining washers and nuts to the screws from underneath. Tighten all four nuts securely.

Final Check: Verify that the hydrofoil is firmly attached and does not move. Re-tighten hardware if necessary before operating the vessel.
Troubleshooting & FAQ
Q: How do I know if this hydrofoil will fit my motor?
A: This hydrofoil is designed for a broad range of outboard motors from 8 to 40 HP, including models from Yamaha, Mercury, Johnson/Evinrude, and more. Check the compatible models table for details. Most importantly, ensure your engine's anti-cavitation plate can accommodate the bolt-on installation.
Q: The product notes say it is not compatible with Mercury 40/50/60 HP 4-Strokes. Is that correct?
A: Yes, that is correct. While the general horsepower range is 8-40 HP, there is a known incompatibility with Mercury 4-Stroke engines in the 40, 50, and 60 HP range. Do not purchase this for those specific models.
Q: What tools are required for installation?
A: The package includes the necessary screws, nuts, washers, and even an installation drill bit. You will need a drill and a wrench to tighten the nuts securely.
