Troubleshooting & FAQ

Q: How do I know if this hydrofoil will fit my motor?
A: This stabilizer is designed for most outboard motors in the 8-40 HP range. Review the compatibility table to confirm fitment for your brand. While it can fit some smaller (down to 4 HP) and larger (over 40 HP) motors, you must measure your anti-cavitation plate to ensure it can accommodate the hydrofoil's dimensions of 13.39" × 13.7". Important: It will not fit Mercury 40, 50, or 60 HP four-stroke models.

Q: What tools are required for installation?
A: Installation requires drilling into your motor's anti-cavitation plate. The package conveniently includes all necessary mounting hardware: four sets of stainless steel screws and nuts, and a 6.5mm drill bit.

Q: What are the main benefits of installing a hydrofoil?
A: A hydrofoil gets your boat on plane faster, keeps it on plane at lower speeds (saving fuel), and improves overall stability and maneuverability. It reduces porpoising and chinewalking for a smoother, safer ride.
