Performance Benefits

The Black Diamond 9.3" x 11" isn’t just a prop — it’s that dependable companion that quietly does its job trip after trip. From the moment you open the throttle, it grips the water cleanly, giving you strong acceleration without hesitation. You’ll feel the boat lift naturally onto plane, staying smooth and predictable whether you’re cutting across open water or easing through a winding channel.

Its three-blade design provides the right mix of power and efficiency — quick response at low speeds and steady thrust when cruising. When you’re navigating tight areas near the dock or trolling through quiet coves, it remains composed and responsive, giving you confidence in every maneuver.

The Phantom Black finish not only gives it a sleek look but also works hard to resist corrosion, salt buildup, and nicks from everyday use. Maintenance is simple — a quick rinse and wipe after a day on the water keeps it looking sharp. The aluminum construction provides flexibility that stainless props don’t — if you scrape a sandbar or graze a submerged log, it’s more forgiving and easier to repair.

Why is this prop a strong choice vs. alternatives?

• Mercury OEM quality: Built with the same engineering standards trusted by Mercury’s own production teams.
• Durable and affordable: Aluminum design offers the right mix of strength, performance, and value.
• Low-maintenance finish: The Phantom Black coating protects against corrosion and wear, keeping the prop looking new season after season.
• Smooth, quiet handling: Balanced design minimizes vibration and ensures consistent grip in the water.
• Versatile fit: Works across multiple small-engine setups thanks to the included rubber hub system.

The Black Diamond 9.3" x 11" is ideal for boaters who value reliability over complication. It’s not about chasing speed records — it’s about knowing your prop will deliver steady, worry-free performance every time you launch.
