Troubleshooting & FAQ

Q: How will this hydrofoil improve my boat's performance?

A: This stabilizer is designed to get your boat on plane faster, reduce or eliminate porpoising (bouncing) and cavitation, and provide a smoother ride in rough water. By improving stability and lift, it can also increase fuel efficiency and allow you to maintain a plane at lower speeds.

Q: How do I know if this will fit my specific engine model?

A: This hydrofoil offers a universal fit for most outboard and sterndrive motors between 5 and 40 HP. Check the compatibility table above to confirm your brand is listed. Installation involves drilling into the anti-cavitation plate, which allows for flexible mounting on various models.

Q: What is the benefit of the dorsal fin style design?

A: The dorsal fin design helps to improve tracking and stability, reducing side-to-side slipping during turns and providing more precise handling, especially at higher speeds.
