Installation Guide
- 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.
- Mark Drill Holes: With the hydrofoil held firmly in place, use a marker to mark the four drilling locations through the mounting holes.
- 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.

- Final Check: Verify that the hydrofoil is firmly attached and does not move. Re-tighten hardware if necessary before operating the vessel.
Troubleshooting & FAQ

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.
