Built tougher than the harshest marine conditions, the Bass Pro Shops Outdoor World Marine Power Pedestal combines smooth movement and rugged craftsmanship. This sleek boat seat pedestal swivels 360 to keep up with the big bite or win a debate happening in stereo. A 3 tilting design prevents premature breaking like on more rigid boat power pedestals, and the lever handle allows smooth operation when you adjust the height. The Bass Pro Shops Outdoor World Marine Power Pedestal sports a 2-3/8 keyed pipe and complies with ABYC Standard H-31 Type B seating. Imported. Sizes: 14.25-21, 22.25-28.25.
