What pulley is needed?
 

I am replacing the Mercury sea water pump on my 454/Bravo with a Jabsco pump.

The Jabsco pump has a flange with 4 mounting holes for the pulley. My stock sea water pump mounts with one nut directly on the shaft of the pump.

The Jabsco pump is the newer style that uses 4/5 nuts to hold the pump to the bracket, not the older "clamp" style.

What pulley do I need and where can I find one for this application with a serpentine belt?

Any help is appreciated.
