Pirjeco 13" Boat Seat Pin Post Pedestal Kit — 3/4" Lock-In Pin, 7x7 Aluminum Base, 360° Swivel

Pirjeco's 13" boat seat pin post kit is a complete 3/4" pedestal base solution that replaces or adds a secure, 360° swivel seat mount for bass boats, pontoons, jon boats and other small craft.

Whether you're retrofitting an older boat or adding a new seating position, this kit supplies a 7" x 7" base plate, a 3/4" lock-in pin mount and a 13" tall pin post socket engineered for marine conditions. Built from aluminum and reinforced alloy steel, the assembly balances strength with corrosion resistance so you can use it in fresh or saltwater without bulky, time-consuming fabrication.

How does this kit fit different boat seats?

The Pirjeco pedestal base is designed for standard non-threaded 3/4" pin post seats and most common marine seat footprints. The 7" x 7" plate aligns with typical bolt patterns, and the open-top socket accepts a wide range of pin posts up to 1.5" diameter.

• Fits standard non-threaded 3/4" pin posts and most marine seat models
• 7" x 7" base plate matches common mounting patterns
• Socket tolerates pin posts up to 1.5" diameter for compatibility

What materials and construction make it boat-ready?

This kit uses marine-grade aluminum for the base plate and reinforced alloy steel in high-stress areas, combining light weight with durability. Reinforced ribs and a solid-steel locking pin reduce flex and prevent accidental detachment in choppy conditions.

• Aluminum base minimizes corrosion and weight
• Alloy-steel reinforcement on load points increases strength
• Solid-steel locking pin secures the seat under movement

Will it swivel and how smooth is the rotation?

The seat mount provides full 360° rotation for easy access and improved ergonomics during long trips. The mechanism is engineered for smooth motion to help when operating trolling motors, casting, or turning to communicate with passengers.

• Full 360° swivel for unrestricted movement
• Smooth operation reduces wear on seat and hardware
• Improves safety when changing direction or using controls

How straightforward is installation and what’s included?

Installation is simple for anyone with basic tools: the kit includes the base plate, the lock-in 3/4" pin seat mount, and a 13" tall pin post socket so there’s no need to source extra parts. Pre-drilled holes on the plate match standard bolt patterns; sealant and marine-grade fasteners are recommended for a watertight installation.

• Complete kit: 7" x 7" base plate, 3/4" pin mount, 13" pin post socket
• Pre-drilled mounting holes align with common decks
• Requires basic hand tools and marine fasteners for installation

Who is this for? Anglers, boat owners and DIYers who need a dependable, corrosion-resistant seat mount will find this Pirjeco kit ideal for replacing worn hardware or adding a new seating position. It's well suited to bass boats, jon boats, pontoons and small cruisers where a stable, swiveling seat improves comfort and function without expensive custom work.
