- Remove the hydrofoil and carefully drill the marked holes using the included 6.5mm drill bit.
- Place the hydrofoil back onto the plate, align the holes, and insert the stainless steel bolts.
- Securely tighten the nuts, ensuring the hydrofoil is firmly attached. Do not overtighten to avoid damaging the plate or hydrofoil.
- Double-check all hardware for tightness before operating your boat.
Troubleshooting & FAQ
How do I know if this hydrofoil will fit my motor?
This hydrofoil is designed for universal fit on most outboard and stern drive motors from 5 to 150 HP. Please check the dimensions (H: 10.25", W: 8.25") and ensure your anti-ventilation plate can accommodate the bolt-on installation before purchasing.
What tools are required for installation?
Installation requires a drill. The kit conveniently includes a 6.5mm drill bit and all necessary stainless steel screws and nuts.
Will this hydrofoil improve hole shot and reduce cavitation?
Yes, a properly installed hydrofoil is designed to help the boat get on plane faster (improving hole shot), maintain planing at lower speeds, and reduce or eliminate propeller ventilation and cavitation, leading to a smoother ride and better fuel economy.
What are the signs that a hydrofoil needs to be replaced?
Inspect the hydrofoil regularly for signs of stress cracks, chips, or fractures, especially around the mounting points. Any visible damage can compromise performance and safety, indicating it's time for a replacement.
How is this aftermarket hydrofoil different from an OEM version?
While many motor brands don't offer hydrofoils as standard OEM parts, our aftermarket stabilizer is engineered to meet or exceed industry standards for performance and durability. It provides a cost-effective solution for improving your boat's handling characteristics.
