SOLAS, the technology leader in the impeller design, creates lots of outstanding advantages built into its products. All SOLAS impellers are made of an ultra high strength, corrosion resistant stainless steel, and are cast in a one-piece mold without bending the edges of the blades to achieve the perfect pitch.
The SOLAS Dynafly 155mm Impeller is designed with SOLAS engineering expertise and manufactured from ultra-high-strength, corrosion-resistant stainless steel. Its one-piece molded construction eliminates the need to bend the blade edges, helping achieve the intended pitch profile.
Pitch selection influences watercraft performance. A smaller pitch can improve acceleration while reducing top speed, whereas a higher pitch can reduce acceleration while increasing top speed. A higher-than-stock pitch may be used for watercraft with more horsepower than stock, while a lower-than-stock pitch may be suitable for certain re-flashed ECU, high-altitude, or high-temperature applications where additional RPM or compensating performance is desired.
SOLAS also provides pitch considerations for limited and modified impeller applications, depending on the desired RPM and speed. Reduced pitch can help accommodate higher carried weight by limiting the volume of water moving through the pump. The SOLAS Dynafly 155mm Impeller is identified by part number YS-DF-14/21.
