Our PWR Yamaha SuperJet & WaveBlaster pump shoe was created from the OEM Yamaha Superjet pump shoe. We 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 Wave blaster 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. We have strong inserts that will exceed stock expectations. Another advantage is the deeper shoe shape, which will scoop more water and create a even flow to most intake grates available. The Jet Dynamics intake grate can work with our pump shoe like you can see in one of our attached pictures.
On top of all that our product has a hydrophobic surface. This surface allows the water to speed up. You will gain acceleration and top speed with all of these advantages.
