Performance Benefits

The instant you push the throttle, the Quicksilver Q4 8M0055561 makes itself known. It grabs the water instantly, lifting the hull with confident power and getting your boat on plane fast. The aggressive 4-blade design isn’t just for looks — it’s tuned for balance and precision. Each blade works together to generate exceptional lift, giving you smoother acceleration and sharper response when you need it most.

Once you’re cruising, the Q4 really shines. Its high-lift geometry keeps your boat steady, even in crosswinds or choppy conditions. It delivers a firm, planted feel through turns, helping you hold tight lines without losing bite or speed. You’ll notice it most in the midrange — smooth, predictable, and responsive, whether you’re towing, fishing, or chasing open water.

Unlike many 4-blade props, the Q4 doesn’t trade off top speed for stability. It matches the best-in-class performance of 3-blade props, giving you the speed you want with the handling you need. And thanks to its stainless-steel construction, it holds its shape under load, ensuring consistent performance season after season. It is strong, corrosion-resistant, and easy to maintain — a quick rinse and polish, and you’re ready for the next trip.

Why Is This Prop a Strong Choice vs. Alternatives?

The Quicksilver Q4 is built for real boaters — people who spend weekends on the water, not just talking about it. It’s made to handle the kind of conditions you actually face: rough wakes, quick throttle bursts, and long runs between spots. Compared to standard aluminum props, it offers a stronger holeshot, better grip through turns, and smoother handling at all speeds.

It’s also incredibly versatile. Whether you’re running a fishing setup, towing skiers, or cruising with the family, the Q4 adapts easily. It gives you that stainless-steel strength and precision without the noise or vibration you’d expect from something this aggressive. Engineered by Mercury’s own team, it meets OEM standards for fit, finish, and balance — so you know it’ll perform exactly as promised. If you want a prop that feels solid, sharp, and ready for anything, this is the one.
