Product Details
Get on plane faster and improve stability with the Whale Tail Hydrofoil Stabilizer FO2002 – Fits 8–40 HP Outboard Motors & Stern Drives. This marine hydrofoil stabilizer is engineered for smaller outboard motors and stern drives, significantly reducing porpoising and cavitation. It fits most engines in the 8 to 40 HP range, with specific exceptions noted for certain Mercury, Volvo, Honda, and Yamaha models.
This part is a direct replacement for SupremeMarine FO2002, UanofCn FO2002, and NorthBoat FO2002.
- Installation: Securely mounts to the anti-cavitation plate (drilling is required).
- Material: Constructed from premium reinforced, marine-grade Nylon-PA66 plastic for durability in harsh saltwater and freshwater environments.
- Performance Gains: Enhances fuel efficiency, provides quicker planing at lower speeds, and improves low-speed maneuverability, especially for aluminum boats, jon boats, and inflatables.

Troubleshooting & FAQ
Will this hydrofoil fit my specific motor?
This stabilizer is designed for a universal fit on most outboard and stern drive motors rated from 8 to 40 horsepower. However, it is not compatible with certain models, including Mercury 40-60 HP 4-strokes, specific Volvo Penta drives, Mercury Bravo II/III drives, and high-horsepower Honda (200+) and Yamaha (350) motors. Always check the exceptions list.
Is drilling into my cavitation plate required?
Yes, installation requires drilling four holes into your motor's anti-cavitation plate. This ensures a secure, rigid mount necessary for withstanding water pressure and providing the intended performance benefits. All mounting hardware and a drill bit are included.
What is the primary benefit of installing this hydrofoil?
The main advantage is improved planing performance. The hydrofoil provides hydrodynamic lift at the stern, allowing your boat to get on plane at lower speeds and stay on plane with less throttle. This also enhances stability, reduces bow rise, and can increase fuel efficiency.
How will I know if the hydrofoil is working correctly?
You should notice a distinct improvement in your boat's performance. Key indicators include faster hole shot (getting on plane), reduced minimum planing speed, better handling and stability, and a significant reduction or elimination of issues like porpoising (bow bouncing) and cavitation.
Can this hydrofoil be painted to match my motor?
Yes, the reinforced nylon material can be painted. For best results, lightly sand the surface, apply a plastic adhesion promoter, and use a high-quality marine-grade paint and clear coat to ensure a durable, long-lasting finish.
What are signs of a failing or improperly installed hydrofoil?
Signs of an issue include excessive vibration from the engine, the hydrofoil feeling loose, or a lack of any noticeable performance improvement. If you experience these, immediately inspect the mounting hardware to ensure it is secure. Cracks in the hydrofoil material also indicate a need for replacement.
