Well, after many years of getting my back pounded on my boat on those rough days, I finally got some seat suspension. I've been looking for a long time and finally found something that looks like it will suit my needs. Most of the stuff out there was too bulky for my application. This actually just replaces my existing seat posts and all the holes lined up perfectly. It's basically a seat post with suspension inside. Now, I'm sure there is a lot more involved, but that is the basic design. The company is called Seaspension. I own a Parker 2310 and although she rides great, she can jar your back bone on any given day. I figured this will save me alot of pain, and alot of chiropractor money in the long run! Here's some pics of the install. The install was so simple on my Parker that it took me about an hour start to finish. For both seats! A plug and play install. I'm taking it out today for a test spin and will post my final thoughts.
