The Quicksilver QA381OR Diamond Propeller is a high-performance propeller designed specifically for Mercury and Yamaha outboard engines. This propeller is crafted with precision and care, using Quicksilver's proprietary Diamondcoat finish, which provides superior protection against corrosion and wear. The Diamondcoat finish is a result of a multi-step process that applies a layer of ceramic micro-beads to the propeller's surface, creating a tough, abrasion-resistant coating that is both durable and attractive.
The Quicksilver QA381OR propeller is a 3-blade design, which is ideal for a wide range of applications. The 3-blade configuration provides excellent thrust and acceleration, making it an excellent choice for both freshwater and saltwater use. The blades are made of high-grade stainless steel, which is both strong and lightweight, ensuring optimal performance and fuel efficiency.
The propeller's pitch is 38 inches, which is suitable for medium to large outboard engines. The pitch is measured from the leading edge of the blade to the propeller hub, and it affects the engine's RPM and the boat's speed. The 38-inch pitch provides a good balance between acceleration and cruising speed, making it an excellent choice for recreational boating, fishing, and water sports.
The Quicksilver QA381OR propeller is also designed with a cupped blade design, which provides better lift and thrust, improving the boat's performance and efficiency. The cupped blade design also reduces cavitation, which can cause vibration and noise, providing a smoother and quieter ride.
In summary, the Quicksilver QA381OR Diamond Propeller is a high-quality, durable, and performance-driven propeller that is ideal for Mercury and Yamaha outboard engines. Its Diamondcoat finish provides superior protection against corrosion and wear, while its 3-blade design provides excellent thrust, acceleration, and fuel efficiency. Its 38-inch pitch provides a good balance between acceleration and cruising speed, making it an excellent choice for recreational boating, fishing, and water sports. With its cupped blade design, the propeller also reduces cavitation, providing a smoother and quieter ride.
