A water flow guide (10, 60) stationarily mounted in the water box of (20) an underwater pelletizer (12) to selectively direct the pressurized water flowing through the water box in order to more efficiently cool and rigidify the extruded polymer strands and enable the rotary cutter blades (37) to more effectively shear the strands into pellets and to convey the sheared pellets away from the die face (18) and rotary cutter blades (37) of the pelletizer (12) to the water box outlet (26). The water flow guide (10, 60) provides an accurately guided pressurized water flow which enables pelletization of polymers of various diameters and a wide range of specific gravity and rheological characteristics.
