Installation Guide

  1. Position the Hydrofoil: Center the hydrofoil on top of the cavitation plate of your outboard motor or stern drive. Ensure it is placed correctly for optimal performance.
  2. Mark Drill Holes: With the hydrofoil held firmly in position, use a marker to mark the four mounting hole locations on the cavitation plate.
  3. Drill the Holes: Remove the hydrofoil and carefully drill the four marked holes using the included 6.5mm drill bit.
  4. Mount the Hydrofoil: Place the hydrofoil back onto the cavitation plate, aligning the holes. Insert the provided stainless steel screws from the top.
  5. Secure the Hardware: Attach the nuts to the screws from underneath the cavitation plate and tighten them securely. Check that the hydrofoil is firm and does not move.

Troubleshooting & FAQ

Q: Will this fit my Mercury 50 HP 4-Stroke engine?

A: No, this hydrofoil is not compatible with Mercury 40, 50, or 60 HP 4-stroke outboard models. Please check the compatibility list carefully.

Q: Can I install this on a Volvo Penta sterndrive?

A: Yes, it fits many Volvo Penta models. However, certain series like the SX-A, DPS, 280, and 290 require longer bolts and 1" fender washers (not included). It is not recommended for the Ocean Series XDP or models with exhaust through the cavitation plate.

Q: How does this hydrofoil improve the boat's performance?

A: It provides hydrodynamic lift at the stern, which helps the boat get on plane faster, reduces bow rise during acceleration, and minimizes porpoising. This often results in a smoother ride, improved handling, and better fuel economy by enabling stable cruising at lower RPMs.

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.
