Installation Guide
- Ensure the engine is off and the boat is securely trailered or docked. Disconnect the engine's negative battery cable for safety.
- Center the hydrofoil on the anti-cavitation plate of your outboard or sterndrive. Ensure it is positioned for optimal water flow and does not interfere with the propeller.
- Use a marker to carefully mark the four drilling locations on the plate through the mounting holes of the hydrofoil.
- Remove the hydrofoil and use the provided 6.5mm drill bit to drill the four marked holes through the anti-cavitation plate.
- Place the hydrofoil back onto the plate, aligning it with the newly drilled holes.
- Insert the provided stainless steel screws and nuts and tighten them securely. Do not overtighten, as this could damage the plate.
Troubleshooting & FAQ
How do I know if this hydrofoil will fit my engine?
This hydrofoil is designed for universal fitment on most outboard and sterndrive motors from 8 to 40 HP. It also fits many larger engines, with the specific exception of Mercury 4-Stroke 40HP, 50HP, and 60HP models. Always measure your anti-cavitation plate and compare it to the hydrofoil's dimensions (H: 13.39" × W: 13.7") to ensure a proper fit.
What is the main benefit of installing a hydrofoil?
A hydrofoil helps your boat get on plane faster, reduces porpoising and cavitation, and can improve stability and fuel efficiency at lower speeds. The crescent-shaped design of this model is engineered to channel water for maximum lift and control.
What tools are required for installation?
The package includes the necessary stainless steel mounting hardware (screws and nuts) and a 6.5mm drill bit. You will need a power drill and basic hand tools to tighten the fasteners.
