    Did you remove the pump from the resivoir? If it has been removed there is a rubber o-ring on the bottom of the pump that may have been lost or torn with out this o-ring the pump cannot build enough pressure to lift the blade off the ground but it will still turn the blade.
    Hope this helps:confused:
