Anyone here have pictures of those impeller upgrade kits?? I was checking mine out after the last storm, and looks like I have over half a inch of clearance between the impeller, and the housing. Im thinking of adding some form of rubber belting to take up the slack a little. At least on a few of the impeller blades. Also... so do you realy need to do all the blades? or you think just half of them would be fine? I just hate to overtax the little 5hp engine on mine.
