The SOLAS Concord Impeller Yamaha 650 YB-CD-14/18 is designed with SOLAS impeller technology to support tailored acceleration, top-speed, and operating performance. SOLAS manufactures its impellers from high-strength, corrosion-resistant stainless steel and casts them in a one-piece mold without bending the blade edges, helping achieve the intended blade pitch.
Impeller pitch affects watercraft performance. A smaller pitch can improve acceleration while reducing top speed, whereas increasing pitch can reduce acceleration and increase top speed. A higher-than-stock pitch may be used for watercraft with more horsepower than stock. SOLAS limited and modified impeller recommendations may be used in either application, depending on the desired RPM and speed.
A lower-than-stock pitch may be suitable for watercraft with a re-flashed ECU that increases the rev limiter for additional RPM, when applicable. It may also be used for high-altitude or high-temperature applications where horsepower is reduced. Reduced pitch can support applications carrying greater weight by limiting the volume of water through the pump.
