Fizzle R7 Supercharger Impeller (24+ PSI) with Shaft for Sea-Doo 325

Increase top speed, acceleration and throttle response with the Fizzle R7 Supercharger Impeller for Sea-Doo 325 watercraft!

This lightweight, precision machined billet aluminum supercharger packs a big punch!

Typical gains are 5-6+ PSI more boost pressure and 350-400 more RPMs over the OEM supercharger wheel. Maximum boost output is 24+ PSI.

Our supercharger impeller design features aggressive blade geometry for the ultimate experience in acceleration, boost, and top speed gains! This design maximizes efficiency in order to produce major performance benefits without causing a spike in intake air temperatures compared to the OEM supercharger impeller.Patent Pending # 30/035,450

Includes required matching supercharger shaft. This supercharger impeller is a drop-in fit to the OEM Sea-Doo 325 supercharger housing, meaning there is no machining needed for the front or rear housing.

While the new supercharger shaft material has been optimized for increased torsional strength compared to the OEM shaft, the shaft is not indestructible. For this reason, we recommend this impeller upgrade only for competition use, with the understanding that there is no warranty expressed or implied on the impeller, shaft, or any other supercharger or engine components related to the watercraft.
