Offbeat water pumps

Let's see some pictures of different water pumps that everyone has used.
I just found a real cool looking marine pump, it's a Sherwood Brassworks pump, made in Detroit. The pump came off of some old wooden cruise boat and I was thinking of adapting it to use. The pump is a gear style and completely made cast brass with machined brass gears and shafts.
Anyone ever tried something out of the box when it came to wp's?
let's see some pics and hear some ideas......

 

Here's a picture of the pump I found on the boat, and a pic of what it might go on.
Any thoughts?
