I saw several boats, including the 5 man with foot operated bilge systems.  seemed very simple and worked well.  Can someone tell me where to get these?

I was in that boat and I was in one of the seats that these were located, I found it very easy to operate and kept most of the water out with little effort, we also had battery operated pumps incase we took on alot of water.  Anyway we rented this boat from Spencer canoes in Texas and it was already fitted with these pumps so you might give them a call, I don't think he installed them but could sure put you on the right path.

Any info on these?

These pumps are pretty popular in safari boats, and here is where I have gotten them:
