Performance Benefits

You can feel this prop working for you the moment the throttle moves forward. The 9.8" x 9.5" pitch delivers quick lift without strain, giving smaller engines a strong, confident push through the water. It’s perfect for lighter boats that need responsiveness more than raw speed. Acceleration feels clean and steady — you’ll notice the smooth grip as the blades dig in and get you moving without hesitation.

At cruising speeds, handling is predictable and effortless. The balanced design keeps vibration low, so your ride feels calm even when the current shifts or the wind picks up. Docking and slow maneuvers are easier too — there’s no jerky pull or lag when changing direction. This is the kind of prop that lets you focus on the moment, not the mechanics.

The durable aluminum build offers long-lasting strength while staying light enough to protect your lower unit if you hit debris or shallow bottom. That sleek Phantom Black finish doesn’t just look sharp — it resists corrosion and wipes clean with minimal effort, making post-trip maintenance quick and easy.

This Mercury propeller (part number QA2192R) keeps that reputation alive with its smart, balanced design and OEM-level precision. It’s strong enough to handle the torque of everyday boating but light and forgiving enough to make maintenance simple.

Compared to stainless steel options, this aluminum prop is more affordable and easier to service, making it a smart investment for casual and frequent boaters alike. It also fits a wide range of outboards through Mercury’s versatile hub system, so it’s as practical as it is dependable. If you’re looking for something that just works — trip after trip, season after season — this is that prop.
