Installation Guide
- Disconnect the battery and ensure the engine is fully tilted up and secured.
- Position the hydrofoil on the cavitation plate, ensuring it is centered and does not interfere with the propeller's movement.
- Mark the drilling locations on the cavitation plate using the holes in the hydrofoil as a template.
- Remove the hydrofoil and carefully drill the marked holes using the included 6.5mm drill bit.
- Place the hydrofoil back onto the cavitation plate, aligning the holes.
- Insert the stainless steel bolts from the top and secure them with washers and nuts from the bottom.
- Tighten the hardware evenly until the hydrofoil is firmly secured. Do not overtighten, as this can damage the cavitation plate.
- Lower the engine and visually inspect for proper clearance before reconnecting the battery.
Troubleshooting & FAQ
Q: How do I know if this hydrofoil will fit my engine?
A: This hydrofoil is a universal fit for most outboard motors and stern drives from 5 to 150 HP. It is not compatible with specific models like Volvo Penta 280/290 outdrives or BMW outdrives on engines over 50 HP. Always measure your cavitation plate and compare it to the product dimensions (10-1/4" H x 8-1/4" W) to ensure proper clearance.
Q: Will I need to drill holes in my engine's cavitation plate?
A: Yes, this is a bolt-on installation that requires drilling four holes in the cavitation plate. The kit includes the necessary stainless steel hardware and a 6.5mm drill bit for your convenience.
Q: What are the signs my boat could benefit from a hydrofoil?
A: If your boat struggles with slow planing, porpoising (the bow bouncing up and down), or cavitation (propeller losing its grip on the water), a hydrofoil can often improve performance. It helps lift the stern, allowing the boat to get on plane faster at lower speeds and improving stability.
Q: What is the difference between an OEM and an aftermarket part?
A: This listing is an aftermarket replacement part (not an OEM component). We build to OEM specifications using comparable-grade materials. Production is done in an ISO9002-certified facility, and each batch is inspected for consistent performance.
Q: How fast do you ship and how much does it cost?
A: We offer fast global shipping—typically 5–15 days worldwide—and standard shipping is free. Expedited options are available at checkout depending on your location.
Q: What is your warranty and return policy?
A: This product includes a 1-year warranty against manufacturing defects under normal use. If something goes wrong, contact our support team with your order details. Returns are accepted within our standard return window (unused & in original condition); please see our policy page or reach out for instructions.
