This ProWatercraft pump shoe was created from the OEM Yamaha Superjet pump shoe. ProWatercraft cut back the “shoe shape” to open up the intake to improve cavitation and hook up. Because one of the more noticeable issues with the older Yamaha Super Jet and Yamaha WaveBlaster is cavitation in the turns when the ski is really leaned over. The pump shoe is the best way to adjust this issue.

The opening is 144mm to fit the stock Yamaha pump. The strong inserts used exceed stock expectations. Another advantage is the deeper shoe shape, which will scoop more water and create an even flow to most intake grates available. ProWatercraft Yamaha Pump Shoe also has a hydrophobic surface, which speeds up water, you will gain acceleration and top speed with all of these advantages.

NOTE: Shown for reference in one of the images is the Jet Dynamics intakegrate which is not included. 

IMPORTANT NOTE: Pump shoes may need to be modified to fit properly. This is the case with all aftermarket aluminum pump shoes.
