Installation Guide
- Safety First: Before starting, disconnect the engine's negative battery cable to prevent accidental starting.
- Position the Hydrofoil: Place the hydrofoil onto the anti-cavitation plate of your lower unit. Ensure it is properly centered.
- Mark Holes: Use a marker to mark the four drilling locations on the plate, using the hydrofoil's mounting holes as a guide.
- Drill the Plate: Remove the hydrofoil. Carefully drill the four marked holes using the included drill bit.
- Mount the Hydrofoil: Place the hydrofoil back onto the plate, aligning it with the newly drilled holes.
- Secure the Hardware: Insert the four included stainless steel bolts from the top and fasten them with the corresponding nuts from below.
- Tighten Securely: Tighten the nuts evenly until the hydrofoil is firm. Do not overtighten, as this can damage the cavitation plate or hydrofoil.
- Final Check: Reconnect the battery cable and perform a test run on the water to check for proper performance.
Troubleshooting & FAQ
Q: How do I confirm this fits my engine?
A: This hydrofoil is designed for a wide range of outboard and stern drive engines from 8 to 40 HP. Please review the compatibility tables on this page. Pay close attention to the specific exceptions noted for brands like Mercury, Honda, MerCruiser, and Volvo Penta to ensure it fits your model.
Q: Will this hydrofoil really improve my boat's performance?
A: Yes, it is designed to improve performance in several ways. The whale tail shape helps lift the stern, reducing bow rise and allowing the boat to plane at lower speeds. This also improves stability, fuel efficiency, and can reduce or eliminate porpoising.
Q: What is involved in the installation? Is drilling always required?
A: Yes, installation requires drilling four holes into your engine's cavitation plate. The package includes a drill bit and all necessary stainless steel mounting hardware. While it is a straightforward process, professional installation is recommended if you are not comfortable with the procedure.
Q: Can I install this on a Volvo Penta stern drive?
A: Yes, it is compatible with several Volvo Penta series, including the SX-A, DPS, and 290 series. However, you will need to source longer bolts and fender washers, as the included hardware may not be sufficient. It is not compatible with the Volvo Ocean Series XDP.
