The Shim Foil Drive Gen2 is a small tuning part that matters when your Foil Drive Gen2 doesn’t naturally sit “just right” on the board. This can happen on step-bottom shapes, boards with a specific bottom contour, or setups where the mounting area creates an unwanted angle.

Placed under the Foil Drive Gen2 base (around the battery/motor housing area depending on how your unit is positioned), the shim helps correct the unit’s alignment relative to the board and foil axis. In practice, that can translate into:

• reduced drag and cleaner water flow
• a more stable, predictable feel while foiling
• easier takeoff when the setup previously felt inefficient or unsettled

It’s a good add-on for riders who like to tune their gear, especially for e-foil use, downwind foiling, or more performance-oriented setups where small alignment changes make a noticeable difference.

Key features:

• adjustment shim for Foil Drive Gen2
• helps optimize alignment on step-bottom or non-flat mount areas
• improves stability and overall efficiency
• built for long-term marine use
