Installation Guide

1. Safety First: Before starting, ensure the engine is off, disconnected from power, and the boat is securely trailered.
2. Position the Hydrofoil: Place the hydrofoil onto the anti-ventilation plate of your outboard motor. Center it side-to-side and position it fore-and-aft according to the included instructions.
3. Mark the Holes: Once positioned correctly, use a marker to carefully mark the four drill hole locations through the mounting holes of the hydrofoil onto the plate.
4. Drill the Holes: Remove the hydrofoil. Using the included 6.5mm drill bit, carefully drill the four marked holes through the anti-ventilation plate.
5. Mount the Hydrofoil: Realign the hydrofoil with the newly drilled holes. Insert the provided 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 over-tighten, as this could damage the plate or hydrofoil. Periodically check tightness after use.

Troubleshooting & FAQ

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

A: This hydrofoil has a universal design intended for most outboard and stern drive motors from 5 to 150 HP, including major brands like Yamaha, Mercury, Honda, and Suzuki. The key requirement is a suitable anti-ventilation plate with enough flat surface area to drill into for mounting. Please check your motor's horsepower and plate dimensions before ordering.

Q: Does installation require any special tools or extra hardware?

A: No. The package includes all necessary mounting hardware, including four sets of stainless steel screws and nuts. We also provide a 6.5mm drill bit, so you will only need a power drill and basic hand tools to complete the installation.

Q: What is the main benefit of installing this type of hydrofoil?

A: This dorsal fin style hydrofoil provides hydrodynamic lift at the stern, helping your boat get on plane much faster and at lower speeds. This can significantly reduce bow rise, stop porpoising, prevent propeller cavitation, and often improves overall stability and fuel efficiency.

Q: Is the plastic material strong enough for regular use in saltwater?

A: Absolutely. It is manufactured from Marine Grade Nylon PA66 plastic, which is specifically chosen for its high strength, impact resistance, and excellent resistance to UV rays and saltwater corrosion, ensuring long-lasting performance.
