Performance Benefits

From the moment you ease into the throttle, the Quicksilver Q4 8M0055562 makes its presence known. It grabs the water instantly, lifting the hull with purpose and getting you on plane faster than you’d expect from a prop this smooth. Its four stainless blades work together to create exceptional lift and steady thrust, giving you the confidence to push your boat harder through acceleration and turns.

Once you’re running, the difference becomes even clearer. The Q4’s high-lift blade design keeps your boat level and stable, even in chop or while cornering under power. You’ll feel the grip — solid and reassuring — as it holds tight through turns, keeping your boat planted and predictable. It’s smooth in midrange cruising and impressively composed at high speed, giving you a sense of control that few props can match.

Unlike most 4-blade designs, the Q4 doesn’t compromise top-end speed for stability. It matches the performance of 3-blade props while delivering far better handling and lift. And with its stainless-steel construction, it’s tough enough to take on real-world boating — resisting flex, corrosion, and wear through every season. A quick rinse and polish is all it takes to keep it ready for the next run.

Why Is This Prop a Strong Choice vs. Alternatives?

The Quicksilver Q4 8M0055562 is built for boaters who expect more from their gear — those who know the difference between “good enough” and “just right.” It’s the kind of prop that makes your boat feel tuned perfectly to you. The Q4 offers the fast lift, tight grip, and smooth control of a performance prop, but without sacrificing comfort or top speed.

If you’re upgrading from aluminum, you’ll notice the difference immediately. Acceleration feels crisper, handling becomes more precise, and the boat feels steadier in all conditions. Its stainless construction means lasting strength and consistency — no flex, no surprises. Whether you’re chasing fish, cruising with family, or towing skiers, this prop keeps your setup balanced and ready for anything.

Designed by Mercury engineers to meet strict OEM standards, the Q4 is the real deal — refined performance, dependable fit, and quality that speaks for itself.
