This ProWatercraft pump shoe was created from the OEM Yamaha Superjet pump shoe. They 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 Superjet 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. This pump shoe has 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.
On top of all that this product has a hydrophobic surface, which speeds up water, so you will gain acceleration and top speed with all of these advantages.
What You Need to Know:
- Silicone is not included. RTV Silicone is recommended. Use of any other type of silicone, adhesive, etc. will void the warranty.
- RTV silicone requires about 24 hours to cure. Using the product before the cure time will void the warranty.
- Some aftermarket intake grates (top loaders specifically) will decrease speed or performance.
