The Williams 285, 325 & 385 Jet tenders require a different 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 available as a separate component. For the impeller, please look here: https://www.weberpower.com/parts-williams-jet-tender-impeller.html

The Solas jet-pump assembly will not work in any other Weber equipped tenders or watercraft.

Fits 2007-2013 model years only!
