Troubleshooting & FAQ

Q: How do I know if this hydrofoil will fit my motor?

A: This hydrofoil features a universal design intended for most outboard and stern drive motors from 40 to 300 HP. It mounts directly to the anti-cavitation plate. To ensure a proper fit, we recommend measuring your plate and comparing it to the hydrofoil's dimensions of 16.93 × 14.17 inches.

Q: What are the main benefits of installing this hydrofoil?

A: The whale tail design improves performance by getting your boat on plane faster, reducing or eliminating porpoising (bow bouncing), and enhancing stability at both low and high speeds. Its control tips are engineered to improve thrust and reduce drag.

Q: What tools are needed for installation?

A: The package is comprehensive and includes all necessary mounting hardware (4 sets of screws and nuts) and a drill bit. You will only need a drill to create the mounting holes on your engine's anti-cavitation plate.
