The RSR 155-160mm pump upgrade enables you to utilize your existing 155 stator section but get all the benefits from the 160mm Inducer prop and housing. The upgrade kit dramatically reduces prop spin and cavitation as well increasing top speed performance. This affordable kit eliminates the expensive of a 160mm complete pump set-up.
The combination of the custom pitch inducer prop with the additional 160mm housing is a must for anyone wanting to maximize their jet boat performance in all types of water conditions.
* The custom pitched Inducer prop is designed to work with Yamaha supercharged engines. For Naturally Aspirated Engines call for details.
