Source for ST60 paddlewheel plug

[Quickstep192]

It appears that the paddlewheel for my ST60 speedo has bitten the dust. So far, my search for a replacement plug reveals only the paddlewheel plug with the thru-hull. Since I don't need the thru-hull, I wouldn't mind saving a few bucks (and the waste) if I could get just the plug. Any ideas?

Prety much every transducer out there is made by a company called Airmar, try them directly. Good luck.
