I wanted to upgrade to suspension seats for my boat this year. I have 2 pedestal seats up front that I want to change to a shock absorber system. I'm running a Duckworth Advantage, so I called Dewey's Marine (the Duckworth dealer here) and he quoted me over $1,200 plus $400 shipping per seat. The seats are in good condition, so I don't need to replace them, I was just looking for a little cushion on those choppy days. I've done a google search, but didn't come up with much. If you have any sources or have fabricated your own, let me know.
