Attwood Lock’n-Pin 3/4″ Base, Stainless Steel
The Attwood base uses a 4″ x 8″ stainless-steel top plate reinforced with a lip tube for added strength. It fits 3/4-inch non-threaded pedestal pins and includes an acetal bushing to ensure smooth engagement and lasting durability. Best for boaters needing a secure, corrosion-resistant base for standard 3/4″ pins. Caution: compatibility is limited to non-threaded 3/4″ pedestal pins; verify deck clearance before mounting.
CLLOMAGY Pedestal Base Mount Kit (7″ x 7″ Plate)
This CLLOMAGY kit pairs a 7″ x 7″ base with a standard non-threaded 3/4″ pin post socket. It emphasizes corrosion resistance with premium aluminum construction and reinforced ribs for higher load-bearing capacity. Best for pontoon, bass, and jon boats needing robust base support. Choose this if you want a solid base that resists marine corrosion in challenging conditions. Limitation: assembly relies on adjacent deck space for the 7″ x 7″ footprint.
CLLOMAGY 7″ x 7″ Base Plate – 3/4″ Socket
Designed for pontoon, fishing, and bass boats, this base plate provides a smooth installation by drilling six screw holes into the deck and securing the pedestal firmly. Made of stainless steel with a reinforced lip tube for corrosion resistance and strength. Best for boats needing a flush, sturdy seat base with minimal deck intrusion. Limitation: screws are not included, so plan for appropriate fasteners.
marinexplore 7″ x 7″ Base Plate (2 Pack)
Marinexplore offers a two-pack of 7″ x 7″ bases in premium stainless steel, designed for universal 3/4″ pin posts. It emphasizes precise interface with 3/4″ sockets to minimize movement and vibrations. Best for users upgrading multiple stations or adding seats across a deck. Caution: screws not included; verify deck thickness and hole clearance before drilling.
Buying Guide
What to consider when choosing a flush mount boat seat base:
- Pin compatibility: Most options use a standard non-threaded 3/4″ pin post socket. Confirm your seat post matches this size to avoid fit issues.
- Plate size and deck space: A 7″ x 7″ plate offers broad support but requires more deck clearance. A smaller 4″ x 8″ base saves space but may offer less load distribution.
- Material and corrosion resistance: Stainless steel bases resist saltwater better than aluminum in many conditions. For high-abrasion environments, reinforced lips and ribs add lasting strength.
- Installation effort: Bases with drilled screw holes demand precise deck measurements. Pre-assembly and marking can streamline installation.
- Load-bearing needs: Heavier boats or frequent seat swiveling benefit from reinforced rib structures and solid post sockets.
How to choose among the top picks
- If you need maximum corrosion resistance and a proven track record, start with the Attwood base for a 4″ x 8″ footprint and a stainless top plate.
- For marine decks with multiple seats, consider the 7″ x 7″ CLLOMAGY and marinexplore kits to cover several mounting points with sturdy aluminum or stainless baselines.
- Choose Pirjeco’s universal 7″ x 7″ aluminum base if you require a low-profile option with direct OEM-style compatibility.
