The Pitch Components 155/75 6-vane pump is a CNC machined, 2 part, set back pump ("set back" meaning: the entire stator section is moved 2" backwards, which results in more water inside the pump at all times, in front of the impellers - which is extremely useful when doing tricks).
This pump is well suited for engines up to roughly 900cc.
This pump is highly recommended for engines like the Yamaha 701cc and 760cc.
