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 Br***works 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 br*** with machined br*** 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?
