Performance Benefits
What makes the Q4 stand out is how natural it feels in motion. You’ll feel the lift as soon as you throttle up — that smooth, assertive rise that gets your hull on plane fast. The acceleration is crisp without being harsh, and once you’re cruising, the prop stays locked in like it’s reading the water’s mind. Four blades give you that extra bit of grip when cornering or running through chop, while the stainless-steel build keeps vibrations low and control high.

Midrange response is where the Q4 really shines. It’s steady, confident, and balanced — no wandering, no hesitation. You’ll notice a cleaner transition between power bands, making it easier to hold a consistent speed or fine-tune your trim for comfort. And when it’s time to open up, the top-end speed rivals that of a 3-blade propeller, giving you the best of both worlds: control and velocity.

Maintenance-wise, stainless steel means fewer worries. It’s tough enough to handle debris and consistent use without losing its edge. That means more weekends on the water and fewer afternoons spent wrenching in the driveway.

Why is this prop is a strong choice vs. alternatives?
If you’re the kind of boater who values feel as much as speed, this Mercury propeller is worth every spin. You’re getting genuine Mercury OEM engineering — the same quality trusted by seasoned anglers and performance boaters alike. The Q4’s design isn’t just about brute force; it’s about refinement. It gives you reliable holeshot, smooth midrange cruising, and handling that feels intuitive in your hands.

Compared to many stainless options, it’s easier to maintain and works beautifully across a wide range of boats and conditions. Whether you’re swapping out from aluminum or upgrading from a 3-blade, you’ll notice the difference instantly. It’s a propeller built for real-world boaters who want more than numbers on paper — they want the kind of performance that feels right every time they push the throttle forward.
