The Mercury 47-20945 Kiekhaefer QuickSilver three-blade stainless steel propeller is a high-performance marine propeller designed to deliver exceptional thrust and efficiency for outboard motors. This propeller is specifically engineered for use with Mercury outboard motors and is identified by the Mercury part number 47-20945.
The QuickSilver propeller is constructed from corrosion-resistant stainless steel. Its three-blade design, with a pitch size of 20 inches, delivers superior power transfer from the engine to the water. It is precisely balanced to provide smooth, quiet operation and reduce vibration. The blade design has a slight pitch rise, which enhances hole shot, top end speed and reduces cavitation.
The propeller's three blades are carefully engineered to provide a balanced and efficient power transfer to the water, reducing the amount of work the engine needs to do, which translates into improved fuel efficiency and greater overall performance. The propeller's design also helps to minimize the amount of bow rise during acceleration, providing a smoother, more stable ride.
Additionally, the Mercury 47-20945 QuickSilver propeller features a durable, electro-galvanized hub, which further enhances its corrosion resistance and ensures long-lasting performance. The propeller also comes with a stainless steel shaft, which is strong and resilient to the corrosive marine environment.
Overall, the Mercury 47-20945 Kiekhaefer QuickSilver three-blade stainless steel propeller is an excellent choice for boaters looking to maximize the performance of their outboard motor. Its high-quality construction, durable materials, and efficient design make it a top performer in the marine environment.
