Performance Benefits

The Quicksilver Q4 14.6" x 23" Left-Hand propeller brings a rare mix of muscle and finesse. You’ll feel that punch the second you roll into the throttle — a solid, confident holeshot that lifts the hull quickly and cleanly onto plane. The four-blade design holds tight through turns and stays composed even when the water gets choppy. Every push of power feels smooth and deliberate, never rushed or uneven.

At cruising speeds, this Mercury propeller settles in beautifully. It hums along with quiet confidence, offering steady midrange performance that makes long runs comfortable and controlled. The balance is so natural, you’ll find yourself trimming less and enjoying the ride more. When it’s time to open it up, the Q4 doesn’t hold back — it runs with top-end speed that rivals most 3-blade props while giving you superior handling and grip.

Built from premium stainless steel, this prop isn’t just strong — it’s dependable. It shrugs off debris, resists corrosion, and keeps its edge season after season. Less maintenance means more weekends on the water, and that’s what it’s all about.

Why is this prop is a strong choice vs. alternatives?

This isn’t a prop that just checks boxes; it’s one that changes how your boat feels on the water. With genuine Mercury engineering behind it, the Quicksilver Q4 offers that hard-to-find mix of speed, lift, and control that every boater wants but few props deliver consistently. You’ll get reliable performance from the moment you launch to the last mile of the day.

If you’re stepping up from aluminum or even an older stainless model, the difference is immediate. The Q4 grabs the water harder, planes faster, and tracks straighter — especially in turns or when running through chop. It’s forgiving when you need it to be and fierce when you want it to be. Whether you’re running solo or loaded down with gear, this prop feels tuned for real-world boating — not just perfect test conditions.
