Intro to Hydrofoil Attachments

Why Install a Hydrofoil on Your Outboard?

Adding a hydrofoil to your outboard can address common performance issues, such as excessive bow rise, sluggish hole shots, or porpoising. By improving planing efficiency, hydrofoils are particularly beneficial for small to mid-sized boats. Users on /r/boating frequently share how this affordable upgrade has transformed their ride, enhancing fuel economy and creating a smoother experience overall.

How Does Someone Pick and Install a Hydrofoil?

• Select the Right Model: Ensure the hydrofoil is compatible with your engine’s horsepower range and cavitation plate dimensions.
• Installation Process: Most hydrofoils bolt onto the cavitation plate using pre-drilled holes. Slip-on models are also available for easier installation without drilling.
• Follow Manufacturer Guidelines: Use proper torque specifications during installation to secure the hydrofoil firmly.
• Test and Adjust: After installation, test the hydrofoil in calm water. Fine-tune your trim settings to optimize ride height and angle for best results.

Performance Boost Realized

Scenario: A 17-foot runabout with a 90HP outboard struggled with slow planing when fully loaded. After installing a hydrofoil, the boat jumped onto plane faster, maintained lower-planing speeds, and consumed less fuel. Passengers immediately noticed a reduction in bow rise and drag, leading to a more comfortable and economical ride.
