Performance Benefits

The Quicksilver Q3 3-Blade Stainless Steel Propeller isn’t just a prop — it’s a performance enhancer. When you hit the throttle, the high-rake blades bite into the water, giving you instant lift and powerful forward thrust. The design helps your boat plane faster, even under heavier loads, and keeps it steady as speed builds. The result? Smooth, predictable handling from idle to wide-open throttle.

At cruising speeds, you’ll notice how effortlessly the Q3 maintains grip and stability. The 18-inch pitch gives you the muscle to push for top-end speed without sacrificing acceleration. It’s built for efficiency, translating more of your engine’s torque into thrust — meaning less strain, better fuel economy, and a ride that feels balanced no matter the conditions.

Because it’s made from premium stainless steel, the Q3 doesn’t flex under pressure. You’ll get consistent performance season after season, with blades that hold their edge and a finish that resists corrosion in both saltwater and freshwater. Whether you’re running across open bays or carving through coastal chop, this prop makes every trip feel controlled, responsive, and rewarding.
