What is inside diameter of this. shaft size. Also outside diameter of entire impeller. thx?
Unfortunately Sierra does not have sizes on impellers. We can only cross reference it by the OEM number. So if you need more assistance call us at 1-800-914-1123. We will either need a model number or engine and year.
