CLLOMAGY Boat Seat Base Mount for 3/4″ Pin Post Socket

Best for pontoon, fishing, jon, and bass boats needing a sturdy, corrosion-resistant base. The 7″ x 7″ plate accommodates standard non-threaded 3/4″ pin posts, simplifying installation on decks or floors. The base is designed to lock securely after drilling six screw holes and inserting the center post, enabling smooth swiveling and stable seating. Caution: ensure your deck thickness matches the base mounting pattern for a flush fit.
Attwood 1002 Lock’N-Pin 3/4″ Seat Mount

Better for everyday boating with a softer sit, thanks to the 2-3/4″ steel pin and spring. The mount is black E-Coated with a 3-degree tilt and an installed height of 2 inches, offering a compact profile for tighter spaces. Use this when you want a reliable, padded-feel seat anchor in smaller cockpit areas. Limitation: tilt is modest, so extreme swivels may require a larger mounting footprint.
Marinexplore Boat Seat Base 2 Pack

Best for jon boats and small to mid-sized crafts needing stainless steel corrosion resistance. The 7×7″ base plate is designed for 3/4″ pin posts and prevents vibration and noise, delivering a steadier ride. Choose this when longevity and low maintenance are priorities. Caution: screws are not included, so you’ll need compatible fasteners for your deck material.
MATINA Boat Seat Base (2 Pack)

Best for lightweight installations where corrosion resistance matters. The bases are aluminum, cast in one piece with smooth finishes. They are designed for 7″ x 7″ mounting with a 3/4″ pin post, and feature an acetyl bushing for a snug fit that minimizes wobble. They reduce ship weight and simplify upgrades on decks with limited space. Limitation: aluminum bases may show wear if frequently abraded or hammered during maintenance.
CLLOMAGY Boat Seat Pedestal Base Kit

Best for complete installation on pontoon, fishing, jon, or bass boats. This kit includes a 7″ x 7″ base plate and a 3/4″ pin post setup designed for easy replacement of old seats and adding new seating. The kit uses premium aluminum and reinforced ribs for higher load bearing and long-term stability. Caution: ensure pin post compatibility with your existing seat hardware to avoid fit issues.
Boat Seat Base Mount For 3/4″ Pin Post Socket

Best for quick upgrades on many marine seats. The 7×7″ base plate fits standard 3/4″ pin posts and allows flush mounting on decks with a straightforward drilling pattern. The design emphasizes easy installation and solid seating after securing the six screws. Limitation: not all boat models may use the same pin post dimension, so verify compatibility before purchase.
Buying Guide
Key considerations:
- Pin post compatibility: Most bases use a 3/4″ pin post; confirm your seat hardware matches.
- Material and corrosion resistance: Aluminum is light and corrosion-resistant; stainless steel offers superior rust resistance in saltwater.
- Deck mounting: Check hole size (commonly 2.5–3 inches) and screw pattern to ensure a flush, secure fit.
- Weight and load: Heavier bases provide durability but add deck load; balance with boat size and seating needs.
- Height and adjustability: Fixed vs. adjustable pedestals affect comfort and fitting in restricted spaces.
