Product Details
This dorsal fin style Hydrofoil Stabilizer – Fits Outboard Motors & Stern Drives 5-150 HP (Improves Performance & Stability) is designed to enhance your boat's handling, stability, and fuel efficiency. It fits a wide range of Mercury, Yamaha, Honda, Suzuki, and Tohatsu outboard motors and stern drives with horsepower ratings from 5 to 150 HP, supporting both 2-stroke and 4-stroke engines. By getting your boat on plane faster and reducing bow rise, it provides a smoother, more controlled ride, especially in choppy water.
It serves as a direct interchange for Uanofcn FO2001, SeaSierra 19HS, and QuickMariner HS001.
- Installation is a straightforward bolt-on process, though it requires drilling into the anti-cavitation plate.
- Constructed from marine-grade, UV-resistant reinforced Nylon PA66 plastic for durability in harsh marine environments.
- The kit includes all necessary stainless steel mounting hardware for a complete installation.

Installation Notes
- Temporarily place the hydrofoil wings on the engine's anti-cavitation plate to find the optimal position. Ensure they do not interfere with the propeller's movement.
- Once positioned, use a marker to mark the drilling points through the mounting holes on the hydrofoil.
- Remove the hydrofoil and carefully drill the marked holes using the included drill bit.
- Place the gaskets (if included) and hydrofoil back onto the plate, aligning the holes.
- Insert the stainless steel bolts and securely fasten them with the provided nuts. Do not overtighten, as this can damage the cavitation plate.
- Check for tightness and ensure there is no movement or play in the installed hydrofoil before operating your boat.
Troubleshooting & FAQ
What are the main performance benefits of this hydrofoil?
This hydrofoil improves boat handling and stability, gets the boat on plane faster at lower speeds, reduces bow rise and porpoising (bow bouncing), minimizes cavitation, and can improve overall fuel efficiency.
Will this stabilizer fit my specific engine model?
It offers universal compatibility for most outboard and stern drive engines from 5-150 HP. However, it is not compatible with Volvo Penta 280/290 outdrives or BMW outdrives on engines over 50 HP. Always check the compatibility table and verify against your equipment.
Is drilling required for installation?
Yes, this is a bolt-on hydrofoil that requires drilling four holes into your engine's anti-cavitation plate. All necessary mounting hardware is included.
What can I expect in terms of improved handling?
You should experience better overall control, especially in rough water. The hydrofoil provides lift at the stern, which helps keep the bow down for better visibility and reduces the tendency of the boat to bounce or wander.
How can I tell if the hydrofoil is correctly installed and working?
A correctly installed hydrofoil will result in your boat achieving a plane at a-lower-RPM, reduced bow rise on acceleration, and less porpoising at speed. If you don't notice these improvements, re-check the installation for tightness and proper positioning.
