• Compatibility and upgrade-friendly: Fits standard 2-7/8″ marine posts, making it a direct upgrade for many existing seat pedestals—no complicated re-engineering required.

Recommended Applications:

• Ideal for fishing boats (bass boats, flats boats, center consoles) where the operator or passenger needs to adjust fore/aft and rotate easily.
• Perfect for pontoon helm chairs where comfort, flexibility and durability matter.
• A solid upgrade for any vessel looking to modernize seating hardware and enhance ergonomics.

Installation Tips:

• Confirm your pedestal post diameter is 2-7/8″ before ordering—this mount is specifically designed for that size.
• Use quality marine-grade fasteners when mounting the platform to your seat to ensure secure and corrosion-resistant installation.
• After installation, rotate the swivel and slide the seat through its full range to verify smooth movement and proper lock engagement.
• Periodically inspect the self-lubricated pads and swivel base for wear or corrosion, especially in saltwater applications, and rinse with fresh water after exposure.

User Experience Summary:
Once installed, users appreciate how the seat glides smoothly forward and backward under fingertip control, without catching or grinding.

The 360° swivel is often cited as a “game-changer” when casting or maneuvering in tight quarters. The high-strength aluminum platform gives confidence even during rough chop, and the powder-coating resists corrosion for years of reliable use.
