The SOLAS Concord Impeller 18/22 is designed with SOLAS impeller technology to support acceleration and top-speed tuning through pitch selection. SOLAS impellers are made from ultra high-strength, corrosion-resistant stainless steel and cast in a one-piece mold. This manufacturing process avoids bending the blade edges and is intended to achieve consistent pitch.
The 18/22 pitch configuration provides a specific balance of performance characteristics for applicable watercraft setups. SOLAS explains that smaller pitches improve acceleration while reducing top speed, whereas increased pitch can reduce acceleration and increase top speed. A higher pitch than stock may be used for watercraft with more horsepower than stock.
Depending on the application and desired RPM and speed, limited and modified impeller recommendations may be used. A lower pitch than stock can be used where applicable for watercraft with a reflashed ECU that increases the rev limiter, high-altitude or high-temperature conditions where horsepower is lost, or increased carrying weight where reduced pitch helps limit the volume of water through the pump. The SOLAS Concord Impeller 18/22 is identified by part number YH-CD-18/22.
