I have 3 MP 40 and like everything else you have to do the maintenance wich doesn't really take long. I soak the wet side in vinegar for a few minutes while I have a water change, brush off any coralline and make sure the propeller moves freely after cleaning. Since then no problems... Dang, I think I just jinxed myself! haha hope this helps. Al
