The SOLAS Concord Impeller (Part YQ-CD-12/18) is engineered to enhance the performance and durability of Yamaha SJ watercraft. Crafted from ultra high strength, corrosion-resistant stainless steel, this impeller is cast in a one-piece mold to ensure optimal blade integrity and pitch accuracy. Its design facilitates improved acceleration, top speed, and overall efficiency, making it an excellent choice for seasoned boaters and performance enthusiasts alike. The impeller’s features include a smaller pitch that boosts acceleration and reduces top speed for more responsive handling, while a higher pitch can be used to increase top speed at the expense of acceleration. For boats with higher horsepower, selecting an impeller with a higher pitch than stock can provide additional performance gains. The SOLAS Concord Impeller is versatile, with recommendations for limited and modified configurations tailored to specific engine modifications or operating conditions. For high altitude or high temperature environments where engine power may be compromised, a lower pitch impeller helps maintain performance. Additionally, this impeller can be used with re-flashed ECUs that increase RPM limits, ensuring consistent power output. Designed to carry higher loads, the impeller’s reduced pitch helps limit water volume through the pump, optimizing fuel efficiency and reducing strain on the engine during heavy-duty operations. Built with quality and precision, the SOLAS Concord Impeller is a reliable upgrade for Yamaha SJ owners seeking improved boat handling, speed, and durability in demanding conditions.
