• 1 x Hydrofoil Stabilizer (HS001-White)
• 4 x Sets of SS316 bolts, nuts, and gaskets

Installation Guide

Follow these general steps for installation. Professional installation is recommended for optimal performance and safety.

1. Center the hydrofoil on the anti-cavitation plate of your outboard or sterndrive motor. Ensure it is positioned correctly for your specific engine model.
2. With the hydrofoil held firmly in place, use a marker to mark the locations for the four mounting holes.
3. Remove the hydrofoil and carefully drill the four marked holes through the cavitation plate. Start with a smaller pilot bit if necessary.
4. Place the rubber gaskets between the hydrofoil and the cavitation plate to reduce vibration.
5. Align the hydrofoil with the drilled holes and insert the SS316 bolts from the top.
6. From underneath, secure the bolts with the provided nuts and washers, tightening them evenly until the hydrofoil is firmly attached. Do not overtighten.

Troubleshooting & FAQ

How do I confirm this fits my engine?
This hydrofoil offers a universal fit for most outboard and sterndrive motors in the 5-150 HP range. It is confirmed to work with major brands like Yamaha, Mercury, Honda, Suzuki, and Tohatsu. Please check the compatibility table and ensure your engine's cavitation plate has sufficient space for mounting (each wing is 10-1/4" × 8-1/4").

What are the main performance benefits?
Installing this hydrofoil helps your boat get on plane faster, reduces or eliminates porpoising (bow bounce), and improves overall stability at speed. Its design avoids the drag associated with older, cupped hydrofoils. It's especially effective for improving the performance of aluminum boats, jon boats, and inflatable boats.

Is this effective for any size motor in the 5-150 HP range?
While it is designed for the broad 5-150 HP range, performance gains are often most noticeable on smaller motors. Some sources indicate the optimal range is 5-40 HP, where it provides a significant lift for lighter boats.
