Performance Benefits.

The Mercury Quicksilver Black Diamond 13" Pitch Propeller delivers a ride that feels confident from the first turn of the key. As soon as you throttle up, you’ll notice how smoothly it grips the water no slip, no hesitation, just clean, steady power. It’s quick to plane and holds its line with confidence, even when conditions change.

Once on the move, the three-blade design comes into its own. It delivers a blend of lift and control that keeps your boat stable, responsive, and efficient. The acceleration feels natural and linear, making it easy to maintain cruising speed or glide through turns without losing balance. Even at lower speeds, this prop provides smooth tracking and easy maneuverability around docks or shallow waters.

Durability is built in. The aluminum construction makes it tough enough for everyday use yet light enough to reduce engine strain and improve fuel efficiency. And because aluminum can flex slightly on impact, it’s far more forgiving (and affordable to repair) than stainless steel something every weekend boater can appreciate.

The high-gloss Phantom Black finish adds a protective layer that resists corrosion, sand, and salt buildup while maintaining that polished look season after season. It’s a prop that works as hard as you do and keeps performing, whether you’re in calm freshwater or salty coastal conditions.

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

The Quicksilver Black Diamond QA3118R isn’t about flash it’s about dependability. It’s Mercury-engineered for real boaters, the kind who value consistency, simplicity, and performance they can feel. If you’re running a smaller outboard and want a prop that gives you reliable lift, smooth cruising, and easy control, this one’s a no-brainer.

Compared to stainless steel props, it’s lighter, more affordable, and easier to maintain. It’s the practical choice for anyone who wants to spend more time on the water and less time thinking about maintenance. It’s not a prop you have to “break in” it’s one that just feels right from the start.

For everyday anglers, family cruisers, or anyone who wants a prop that works quietly in the background while delivering dependable power, the Black Diamond 10" x 13" is exactly that a solid, trustworthy partner beneath the surface.
