I have a problem with the cooling (no tell tale and motor heats up and shuts down). I have checked the tstat and it is okay. I tried running without the tstat and no water. Anyway I think I need to replace the impeller but I need some help here. I have tried to remove the L/U but it will not disengage. I have removed the three bolts and it will drop down about 1" but that's all. Can someone help me out here? I am trying to get it running so I can sell it. It has less than 100 hours on it and is in beautiful shape but I do not want to sell it in this condition.<br /><br />Thanks so much,<br />Dan
