16 to 20 in Adjustable Height 1.77 Snap-Lock Power Post with Seat Mount - Swivl-Eze

The diameter was 1.77. The original Swivl-eze was 1.77 this was more like 2" and since I needed this for my trip I had to grind and sand it down to get it to fit. The original seemed to be better made it came with my 2005 Champion boat. Since I had to make it fit and it's not perfect it's a little lose fitting and I made a shim to keep it from wobbling. Please look into your inspection process. I know I could have sent it back, but like I said I needed it ASAP. Lenny

I have bought many of these swivel eze pedestals and decided to try the adjusting ones. I bought the ones that were too big but they seem to work well. The only negative part is that they are too tight going in. I figure they will loosen up once you ride on them a few times.

This Swivl-Eze product fits the used Nitro Boat I just purchased and is a replacement for two seats pedestals that came with the boat, but were broken. The product is exactly what I was hoping for, and works as advertised.
