I have seen two different impellers on ebay for the Ted Williams 7.5Hp. For the 217.58881 model, does it take the long impeller (approx 1 1/2") with the pin for the standard short one.
From the parts diagram over at www3.sears.com, it looks like the long version impeller. The picture's not a good one, but it's definitely the long one. There's some guy on ebay selling those.
