The Williams Jet tenders require a different impeller & jet-pump assembly than the other Weber powered marine tenders & watercraft. The special 140mm jet-pump assembly is sold without an impeller, and the impeller is a separate component. For the Jet-pump, please look here https://www.weberpower.com/parts-williams-jet-pump-assembly.html. The jet-pump assembly will not work in any other Weber equipped tenders or watercraft.

Please select between the Turbocharged (TC) or naturally aspirated (NA) impellers.
