3/4 in Boat Seat Pin Post 6 in Height - Lock-In Swivel Replacement

In this review of the 3/4 in boat seat pin post, the bottom line is simple: it is a practical, corrosion-resistant replacement post for anglers and boat owners who need a dependable seat mounting solution. The reviewer found the 6 in height and 1.5 in exterior diameter match most standard 7 in x 7 in marine seat pedestal bases, and the lock-in 360 degree swivel design is the single biggest reason to buy because it prevents accidental detachment while allowing smooth rotation during fishing or cruising.

Key Features

• 3/4 in diameter: Provides a standard fit for many marine seat pedestal bases so swapping seats or adding an extra seat is straightforward.
• 6 in height: Gives a convenient seating elevation for comfort and better control when operating foot pedal trolling motors or casting from the helm.
• Lock-in 360 degree swivel: Keeps the seat securely attached to the pedestal base while permitting full rotation for easy repositioning without accidental release.
• Aluminum alloy construction: Delivers a lightweight but sturdy post that resists corrosion in marine environments for long service life.
• Non-threaded steel pin: Adds solid mechanical strength at the connection point to withstand regular use and repeated mounting cycles.
• Multiple sizes available: Offers 6, 11, and 16 options so buyers can choose the height that best suits their boat and seating arrangement.

Who It's For

The 3/4 in boat seat post is best for pontoon, bass, jon, and fishing boat owners who need a simple, durable replacement or want to add an extra seat on deck or dock. It fits most standard 7 in x 7 in marine boat seat base pedestals and is well suited to anglers who need a secure swivel seat while working with a trolling motor or casting.

Those who should look elsewhere include owners of nonstandard or proprietary pedestal systems that do not match a 3/4 in pin or 7 in x 7 in base, and buyers seeking a fully adjustable telescoping pedestal with integrated mounting hardware and cushioning features.
