I pulled my impeller yesterday so I can clean it up. I plan on buying a new one and keeping this one as a spare (figured I should always have one). Question I have is how to get this back in to shape? The diagram on outboardjets website seems to show the bottom side of the blade has a bevel (gentle curve in their words) to it, whereas my impeller certainly seems to be beveled on the topside of the blade (tapering down to the leading edge) and flat on the bottom. I don't want to screw it up any more than I have but I want to fix it. Any good tips? BTW this is a aluminum 6 1/8" impeller used on a 50/35 jet.
