Description
Impeller – Dynafly – 14/21 – Yamaha
The SOLAS Dynafly Impeller YS-DF-14/21 is engineered specifically for high compression ratio jet-pump systems, providing optimized performance and reliability. Crafted from ultra high-strength, corrosion-resistant stainless steel, this impeller features a mirror-smooth finish and polished hub that effectively resist cavitation, ensuring durability and consistent performance in demanding marine environments. Its unique blade geometry enhances both acceleration and top-end speed, helping to eliminate performance holes often encountered in standard setups. The impeller’s pitch is determined by casting rather than bending, offering precise control over its aerodynamic properties for tailored performance. A lower pitch angle is recommended for stock motors to maximize efficiency, while higher pitch angles suit modified motors for improved acceleration. Additionally, the exclusive hub-end water seal prevents contaminants from entering critical components, further extending the lifespan of your pump system. Designed for easy installation and long-lasting operation, this impeller is an excellent choice for boaters seeking to upgrade their jet propulsion system with a reliable, high-performance component.
