That's a Rudder Zinc. With the wires and alligator clip the owner probably used it in marina's that had a lot of stay electricity in the water, it would have helped reduce the sacrificial load on his installed zincs.
still puzzling why two wires, black and red connected together. Only one wire would be needed for anything.

Ok I'll bite... what is AED?
We bought our boat with all the tools and spares the original owner had on the boat when he was running it up and down the east coast and he spent a lot of time in the Bahamas. Found this in a tool box the PO left in the engine room. Can anyone tell me what this is and it's likely purpose?

Only the original owner would know what it is supposed to do. It's an ordinary sacrificial anode with two wires attached.
If it's supposed to be an auxiliary anode, the proper wire color would be green but electricity doesn't really care about the color of the insulation.
As for two wires attached to the same place, that's a mystery as well. I'll bet there's a good story behind this. Just don't laugh until he's out of sight.
BTW: It's interesting how he put the red clip on the black wire and the black clip on the red wire. Maybe a sign that you should get your boat's electrical system checked out by a pro.
Also
If you are in a marina with a lot of freshwater inflows that cause a thermocline of sorts you can lower this over the side down to the saltwater. In other words your boat floats in freshwater on the surface but say 6-8' below is saltwater.
