Review: Excellent high quality replacement option... - I purchased this seat pedestal for my 2001 StarCraft Aurora 21 foot deck boat. It installed very easily in approximately 20 minutes. Be sure you have a REALLY good, large, Phillips screw driver and then a good electric drill with Phillips bit. The screws that go into the deck are substantial and mine were in very solid. They are also quite long. The base and the pedestal are one piece. The piece that mounts onto the seat is a separate piece. When installation is complete the seat just sits down on the pedestal. You can remove the seat for winter storage by simply loosening the rotation knob and lifting straight up. The seat rotates 360 degree, height is adjustable, rotation can be slowed or locked down with a knob and height is locked down with a pull out knob. The unit is solid and quality is excellent. The design is simple and all moving parts are visible and easily accessible for inspection, lubrication, etc. The design was far superior to the broken OEM pedestal I was replacing.
Review: Taller than advertised - I have not installed these in the boat I'm restoring yet, with that said here are my observations. Well made, all screws, knobs, slides, locks, and hardware seem like they will work properly. I do not think there will be a problem with the adjustable pin coming out and seat dropping to the lowest setting like another reviewer posted. If used correctly and knobs are tightened properly it appears like it will hold tight. My complaint is that although the adjustable seat post is 12" to 18"...when you add the seat mount/swivel it adds another 2" to the overall height...14"-20" before adding the seat. In my application that was too high, my feet barely reached the floor (no I do not have short legs) and my girlfriend's feet did not reach the floor. I solved this problem by removing 2-3/4" from both seat post shafts, drilling four new holes, and retapping the knob screws and the inner limit screw. This requires some mechanical skill and took about 3 hours. The first picture is original and revised in the lowest setting. The second picture is original in the lowest and revised in the highest setting. the third picture is material that was removed (note: 4 outer holes did not need to be duplicated in revision). No mounting screws included, but I did not expect any since everyone's application is different and stainless screws are expensive. All in all, I think these will work fine now that the height is proper for my application.

### ⭐⭐⭐⭐ Very Sturdy
*by C***. on May 22, 2024*

This pedestal is very sturdy and works really well. I have this on the drivers captains chair of a pontoon and it works great. It is really hard to lift when I want it to be raised. My only wish is that it would have a spring assist in it so it would raise you up automatically. Then if you put pressure on it you could lower it.
