Performance Benefits

The Mercury Quicksilver Black Diamond 11" Pitch Propeller strikes that perfect balance of power, precision, and comfort. The moment you ease into the throttle, you’ll feel how smoothly it grips the water, no chatter, no slip, just a confident surge that pushes your boat forward with ease.

Once you’re underway, the prop shines in its consistency. It delivers steady acceleration through the range and holds a smooth line in turns, even when conditions change. The three-blade configuration offers balanced lift and thrust, giving your boat the agility to respond quickly while maintaining a calm, predictable ride.

Because it’s crafted from durable aluminum, this prop is both tough and forgiving. It resists corrosion and wear, yet remains lightweight enough to keep your engine efficient and responsive. If you happen to hit a sandbar or debris, aluminum is far easier and more affordable to repair than stainless steel, an advantage every boater appreciates sooner or later.

The high-gloss Phantom Black finish adds not only a clean, professional look but also another layer of protection against the elements. From salt and sand to freshwater grit, it keeps your prop performing like new, season after season.

The Quicksilver Black Diamond QA3114R isn’t built for flash — it’s built for reliability. It’s Mercury-engineered for people who simply want their prop to perform without fuss. It provides dependable thrust, smooth handling, and lasting value at a price that makes sense.

Compared to stainless steel options, it’s lighter, easier to maintain, and far more forgiving. It’s the perfect all-around prop for small- to mid-size boats that need clean takeoffs, steady midrange cruising, and reliable performance every time you hit the water.

For weekend anglers, family boaters, or anyone who values simplicity and confidence, this prop delivers exactly what you need — and nothing you don’t. It’s the kind of gear that just works, letting you focus on the journey, not the hardware.
