Did mine last week. Same issue. Looked identical and the impeller blades appeared to be designed similarly. As long as the rotation moves the impeller in the same way ie. blades appear to move fluid in the same direction you should be good. Everything I read said the same thing, but my new one had no visible "R" or "rev".
