This ProWatercraft Racing pump shoe should fit Kawasaki 650sx, 750, 800, and X2 models with 140mm pump.
The opening fits 140-145 mm to fit the stock Kawi pump that is similar to the 750/800. Another advantage is the deeper shoe shape, which will scoop more water and create an even flow to most intake grates available.
On top of all that our product has a hydrophobic surface, which speeds up water. You will gain acceleration and top speed with all of these advantages.
Some modification to the pump shoe and/or your ski may need to be done for this product to fit properly.
