Hi all -Getting ready for my winter/wet storage and had a questions about deicers:Has anyone here had any experience re-building the bearing, seal and shaft assembly of a Kasco de-icer? My unit is about 5 years old and when I run the motor, it is making a sound that indicates a worn or damaged motor bearing or seal. A dealer wants about $200 to rebuild the unit and I am sure the parts are a lot less.Thanks - Rob
