Impeller Seal #7 | 20mm Driveshaft Rubber Nose Seal (SK-07)
The Impeller Seal #7 is a high-quality replacement rubber nose seal designed for Impros Hooker and select Skat-Trak performance impellers used in 140mm and larger jet pump systems. This seal installs in the front of the impeller and helps optimize water flow through the pump, reduce turbulence, and maintain maximum pump efficiency.
A properly fitted impeller seal is critical for achieving optimal acceleration, hook-up, throttle response, and overall jet pump performance. The #7 seal is designed to fit the common 20mm driveshaft found in many Yamaha and Kawasaki personal watercraft applications utilizing aftermarket performance impellers.
Manufactured from durable marine-grade rubber, the #7 seal provides excellent resistance to water, heat, and harsh marine environments. While included with many new impellers, it is also available separately as a replacement for worn, damaged, or missing seals.
Features
The #7 Impeller Seal is designed for performance impellers utilizing a 20mm driveshaft. Durable rubber construction helps improve water flow characteristics while maintaining proper pump efficiency and reliability.
Benefits
Improves pump efficiency, reduces turbulence around the impeller hub, enhances water flow, and helps maintain maximum acceleration and hook-up. Direct replacement for damaged or missing impeller nose seals.
Compatible Impellers
- Impros Hooker Impellers
- Select Skat-Trak Performance Impellers
- Various 140mm and Larger Pump Applications
Applications
Designed for use on 140mm and larger pump systems utilizing a 20mm driveshaft, including many performance-oriented Yamaha and Kawasaki personal watercraft applications.
Important Fitment Note
The #7 seal should be used with Impros Hooker and compatible Skat-Trak impellers installed in most 140mm and larger pump systems.
If you are installing a Hooker or Skat-Trak 144mm impeller into:
- Yamaha SuperJet
- Yamaha FX-1
You must use the #6 Impeller Seal for proper fitment.
Why Replace an Impeller Seal?
A worn, damaged, or missing impeller seal can negatively impact pump efficiency and water flow. Replacing the seal helps maintain proper impeller performance, reduce turbulence, and ensure maximum pump efficiency.
