I have an old thru hull. Paddle wheel plastic transducer that I would love to hook up to something that can just show me speed. Anything out there?

The old, unpowered ones, basicly took a volt meter. Try hooking up your VOM to it and try the various voltage scales. Then you could look for a similar analog VM or something on ebay with the same voltages.

Looking at this reading vs: your GPS speed reading should give you the prevailing current.
