Sea-Doo 23-PSI 300 Supercharger

Our Sea-Doo 300 supercharger impeller delivers huge performance gains over stock from it’s 23 PSI of boost at 9200 RPM.

Precision CNC machined from aerospace grade 7075 aluminum alloy and anodized in black.  Included is a laser cut spacer also anodized in black to complete the package.

Note: This charger is not a direct drop in, it requires the back housing to be machined to 143mm.

Equivalent boost and performance to the ET-142 and Riva 300 XXX superchargers.

Installation Notes

Impeller is made to fit tight on the shaft. Using a heat gun on high setting heat up the area around the center of the impeller for 60 – 90 seconds. Once heated it will slide onto the shaft without requiring any force. Do not use a open flame tool like a torch as it can overheat and damage the impeller.
