Hydrofoil Stabilizer – Fits Outboard Motors 5-150 HP (Replaces SeaSierra FO2001, QuickMarine HS001)

Hydrofoil Stabilizer – Fits Outboard Motors 5-150 HP

This hydrofoil stabilizer is engineered for outboard motors and stern drives ranging from 5 to 150 HP. It mounts directly to the anti-ventilation plate to enhance performance by improving handling, reducing bow rise, increasing fuel efficiency, and helping the boat get on plane faster. Its dorsal fin style design provides an enhanced wing surface area for maximum lift and stability.

This part is a direct replacement for SeaSierra FO2001, QuickMarine HS001, UanofCn FO2001, Xingrong HS001, and NorthBoat HS001.

• Installation: Mounts to the anti-ventilation plate with the included stainless steel hardware.
• Material: Constructed from high-strength, marine-grade UV-resistant Reinforced Nylon PA66 plastic for durability in harsh marine environments.
• Compatibility: Universal design fits most 5-150 HP outboard motors and stern drives, including 2-stroke and 4-stroke engines.

Installation Guide

1. Safety First: Ensure the outboard motor is turned off and the battery is disconnected before starting the installation.
2. Position the Hydrofoil: Place the hydrofoil onto the anti-ventilation plate, ensuring it is centered and sits flush against the surface.
3. Mark Drill Holes: Use a marker to carefully mark the four drill points through the mounting holes of the hydrofoil onto the plate.
4. Drill the Holes: Remove the hydrofoil and drill the marked holes using the included 6.5mm drill bit. Ensure you drill straight through the plate.
5. Mount the Hydrofoil: Align the hydrofoil with the newly drilled holes and insert the stainless steel screws from the top.
6. Secure the Hardware: Attach the nuts to the screws from the underside and tighten them securely. Do not overtighten, as this could damage the plate.

Troubleshooting & FAQ

Q: How do I confirm this fits my engine?

A: This hydrofoil offers a universal fit for most outboard motors and stern drives in the 5-150 HP range. To ensure compatibility, we recommend measuring your engine's anti-ventilation plate and comparing it to the hydrofoil's dimensions of 10-1/4" × 8-1/4".

Q: What benefits can I expect after installation?

A: A properly installed hydrofoil helps your boat get on plane faster, reduces bow rise for better visibility, minimizes porpoising and cavitation, and can improve fuel economy at planing speeds.

Q: Is drilling into my engine's cavitation plate safe?

A: Yes, this is the standard installation method for bolt-on hydrofoils. The anti-ventilation (cavitation) plate is designed to accommodate such accessories. Use the included hardware and follow the instructions carefully.
