Installation Guide

1. Position one hydrofoil wing on the engine's anti-cavitation plate to find the optimal placement.
2. Use a marker to indicate where to drill through the mounting holes in the hydrofoil.
3. Remove the wing and carefully drill the marked holes using the included drill bit.
4. Place the provided gasket (if included) between the hydrofoil wing and the plate to ensure a snug fit.
5. Align the hydrofoil wing with the drilled holes and insert the stainless steel bolts.

Troubleshooting & FAQ

Q: How do I know if this hydrofoil will fit my engine?
A: This hydrofoil is designed for a universal fit on most outboard motors and stern drives from 5 to 150 HP. It is not compatible with Volvo Penta 280/290 outdrives or BMW outdrives on engines over 50 HP. Please check your anti-cavitation plate dimensions against the hydrofoil's size (Each Wing: 260 mm × 210 mm) to ensure proper clearance and fit.

Q: Does this require drilling to install?
A: Yes, installation is bolt-on and requires drilling four holes in your engine's anti-cavitation plate. All necessary stainless steel mounting hardware and a drill bit are included in the package to simplify the process.

Q: What is the main benefit of installing a hydrofoil?
A: A hydrofoil significantly improves boat handling and stability. Its primary benefits include getting the boat on plane faster at lower speeds, reducing or eliminating bow rise and porpoising (bouncing), and improving fuel efficiency by minimizing drag and cavitation.
