The SOLAS Concord Impeller Pol PA-CD-15/21 is designed with SOLAS impeller technology focused on performance and precise pitch. SOLAS manufactures its impellers from ultra-high-strength, corrosion-resistant stainless steel and casts them in a one-piece mold. This construction avoids bending the blade edges and helps maintain the intended pitch profile.
Impeller pitch affects the balance between acceleration and top speed. 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 suitable for watercraft with more horsepower than stock, while a lower-than-stock pitch may be used for certain applications requiring additional RPM.
Depending on the application, lower pitch options may be used with a re-flashed ECU that increases the rev limiter, at high altitude or high temperatures where horsepower is reduced, or when carrying additional weight. SOLAS also notes that limited and modified impeller recommendations can be used in either application based on the desired RPM and speed.
