Hi All- This is what my impeller looks like now- It was new when it went into the pump, along with a lipped bronze wear ring, and had .030 clearance between the front of the impeller and the edge of the wear ring lip. Any idea as to why it looks like this now? The wear ring is still fully seated, and I have no front or back movement in the shaft, but I haven't pulled the pump to check the thrust bearing yet. The bearing was also new at the same time. Any help is greatly appreciated. Thanks in advance, Stan[IMG]http://www2.***boat.com/image_center/data/500/68DSC00003-med.jpg
