I talked to Scott a couple years ago about an SS raw water pump. They had suddenly stopped carrying the version I wanted which uses a pressed-on pulley. Scott told me that they still had them, but they didn't list them anymore because amateurs were hammering the pulleys on and destroying the bearings, which of course resulted in unnecessary warranty claims. He sold me one after I told him I wasn't a mechanically challenged moron.
BTW, their pumps are far superior to the OEM ones and only slightly more $$.
