A low speed water driven turbine having a housing to be erected vertically in a water course, a water intake and a water outlet, a drive shaft rotatably mounted along a central vertical axis of the housing, a shaft sleeve non-rotatably mounted in the housing and supporting and enclosing the shaft, a guide casing of generally bell-like shape and defining a lower edge, the casing being connected to the shaft sleeve within the housing and extending outwardly from the sleeve to define a reduced cross-sectional area within the housing in the region of the guide casing, a turbine blade mounting hub driveably mounted at the lower end of the shaft, a plurality of turbine blades mounted around the hub and extending outwardly therefrom the turbine blades being mounted at angles with respect to the vertical axis of the housing, and being located to receive water from the reduced cross-sectional portion of the casing, so that water passing down through the housing will flow onto and past the turbine blades and cause rotation of the shaft.
