Performance Benefits

Once you get this prop spinning, you’ll notice how smooth it feels through the throttle range. The Extra Cup blades grab the water with confidence, giving your boat strong mid-range lift and crisp acceleration out of the hole. It’s the kind of control that makes docking, turning, and cruising in chop feel easy.

Durability is another reason boaters swear by the Black Max. The Mercalloy aluminum handles small impacts without cracking, and the Phantom Black finish keeps corrosion at bay season after season. Maintenance is simple—rinse it, check the hub, and you’re good to go. Whether you’re running freshwater lakes or brackish coastal water, this prop takes the everyday beating of real boating life and keeps performing.

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

If you’ve ever compared props, you know stainless steel is great—but it’s not always practical. The Black Max 16436CP1 delivers a similar sense of grip and thrust without the extra weight or cost. It’s OEM Mercury quality, meaning it fits perfectly and runs true out of the box. And because it’s designed by the same engineers who build Mercury engines, it just feels balanced—no vibrations, no guesswork, no surprises.

For boaters who want real-world reliability and solid performance without overspending, this prop hits the sweet spot. You’ll get the confidence of Mercury engineering and the ease of aluminum maintenance, all in one dependable package.
