I was given a 9.9 Evinrude today. The previous owner had seen a motor started with a drill and decided to try it himself. Probably would have worked fine but he used an impact driver and stripped the threads on the crankshaft. So, what can be done? Can the crank be re-threaded? Or would something else work better? I don't know if he spread the taper out on the flywheel. I will have to check that out.
