Boat owners, listen up! This 3/4 inch boat seat post is exactly what you need for adding comfortable seating to your vessel. Measuring 13 inches high with a 1.5 inch outer diameter, it fits most standard 7x7 inch marine boat seat bases perfectly. The aluminum alloy construction means no rust worries, and the non-threaded steel pin with tight-fit nylon bushing keeps everything stable and secure. The slotted design prevents accidental separation from the base, which is super important for safety on the water. It's perfect for pontoon boats, bass boats, fishing boats, cruising boats - you name it! Just remember though - this isn't for helm seats and shouldn't be used at speeds over 5 mph. It comes in different heights (6, 11, 13, and 16 inches) so you can choose what works best for your setup. The 360-degree swivel design lets you rotate smoothly while maintaining good load capacity. Whether you're adding extra seats for fishing buddies or just want more comfortable seating options, this post has you covered. Installation is straightforward and it's built to withstand harsh marine conditions season after season.
