Outboard jets shows that you sharpen from the top, then the bottom and then smooth out the bottom edge. I've read several times that people say to ONLY sharpen from the top of the impeller. So which one is the right way? I'm going to pull my impeller and sharpen it soon and check the liner and all that good stuff. Also, how do I tell if I need to shim the impeller down? Do I just eyeball it or is there some trick to making sure it's right?
