Performance Benefits

The Quicksilver Q4 8M0055560 isn’t just about getting your boat from point A to point B — it’s about how it feels along the way. From the moment you throttle up, the Q4 digs into the water with purpose, giving you that immediate lift and acceleration that makes the start of every run feel powerful and controlled. The four-blade design generates exceptional lift, helping the boat plane faster while keeping it balanced and predictable at speed.

Once you’re moving, the Q4 keeps things steady. Its high-lift blades hold firm in tight turns, keeping your boat planted even in chop or crosswind. Midrange performance is where it really shines — smooth, efficient, and responsive, giving you better control whether you’re cruising or towing. Unlike most 4-blade designs, the Q4 doesn’t trade speed for grip; it runs at top-end speeds comparable to 3-blade props, offering the perfect blend of acceleration and performance.

Durability is built in. The stainless-steel construction resists flexing under load, maintaining consistent performance even after seasons of hard use. It’s corrosion-resistant, easy to maintain, and designed to keep its shape and shine no matter where you run — saltwater or freshwater.

Why Is This Prop a Strong Choice vs. Alternatives?

The Quicksilver Q4 stands out because it’s made for real-world boaters — the kind who know the difference between good and great performance. It delivers explosive holeshot power, steady midrange grip, and reliable handling without compromise. If you’ve been running an aluminum prop, you’ll feel the difference right away.

This prop gives you the same kind of acceleration and lift you’d expect from a high-end stainless model, but with the refinement and control that makes every outing feel smoother. It’s engineered by Mercury to meet OEM-quality standards, ensuring perfect fit and consistent results across a wide range of boats. Whether you’re chasing fish, towing skiers, or cruising with family, the Q4 adapts seamlessly. It’s a prop built to perform, season after season.
