The SOLAS Concord Impeller 13/20 is engineered by SOLAS, a technology leader in impeller design. It is made from ultra-high-strength, corrosion-resistant stainless steel and cast in a one-piece mold. This construction avoids bending the blade edges and helps achieve the intended pitch for consistent impeller performance.
The 13/20 pitch configuration reflects the relationship between acceleration and top speed. Smaller pitches 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 also provides application guidance for different operating conditions. 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 used with a re-flashed ECU that increases the rev limiter for higher RPM when applicable, or for high-altitude and high-temperature operation where horsepower is lost. Reduced pitch may also be used when carrying more weight to limit the volume of water moving through the pump.
