Loose impeller story..My boat was another one of those "lake ready" boats that has ultimately needed everything replaced and re-engineered. I had miserable flat performance when I got the boat. Lots of RPM and little speed. Upon rebuilding the jet pump, the wear ring was long gone and a rock had wedged itself in the bowl and machined a huge groove in the impeller (as if on a lathe). One more run would have cut in half like slices of bologna and trashed everything. Ha. I can laugh now. Wasn't funny then.
