I bought a 1999 TS770 on eBay. The impeller binds so tight against against the bottom of the wear ring that I can't turn the engine over. The impeller does not rub against the upper 2/3 of the wear ring therefore the impeller is okay. (I pulled the wear ring off and now the impeller unit turns freely). I suspect salt water corrosion on the wear ring. Two questions: Can I just lightly mill the inner bottom of the wear ring on a lathe to get some clearance? Second question: I want to pull the impeller to have it sent in and checked. It's just hanging on the end of the shaft in the fiberglass tunnel (all other pump components are removed). I can pull it back and forth along the shaft about 1/4" but it will not come off even with fierce hammering at it. Is the impeller splined on the shaft? The end nut at the back has been removed with the short shaft so I don't see what is holding it back, especially since it moves up/down on the long shaft about 1/4".
:( Any advice?
