Installation Guide

1. Safety First: Ensure the outboard motor is turned off and the battery is disconnected before starting the installation.
2. Position the Hydrofoil: Place the hydrofoil onto the anti-ventilation plate, ensuring it is centered and sits flush against the surface.
3. Mark Drill Holes: Use a marker to carefully mark the four drill points through the mounting holes of the hydrofoil onto the plate.
4. Drill the Holes: Remove the hydrofoil and drill the marked holes using the included 6.5mm drill bit. Ensure you drill straight through the plate.
5. Mount the Hydrofoil: Align the hydrofoil with the newly drilled holes and insert the stainless steel screws from the top.
6. Secure the Hardware: Attach the nuts to the screws from the underside and tighten them securely. Do not overtighten, as this could damage the plate.

Troubleshooting & FAQ

Q: How do I confirm this fits my engine?

A: This hydrofoil offers a universal fit for most outboard motors and stern drives in the 5-150 HP range. To ensure compatibility, we recommend measuring your engine's anti-ventilation plate and comparing it to the hydrofoil's dimensions of 10-1/4" × 8-1/4".

Q: What benefits can I expect after installation?

A: A properly installed hydrofoil helps your boat get on plane faster, reduces bow rise for better visibility, minimizes porpoising and cavitation, and can improve fuel economy at planing speeds.

Q: Is drilling into my engine's cavitation plate safe?

A: Yes, this is the standard installation method for bolt-on hydrofoils. The anti-ventilation (cavitation) plate is designed to accommodate such accessories. Use the included hardware and follow the instructions carefully.
