Performance Benefits

The Quicksilver Q3 15.3" x 14" propeller is all about balance — that rare mix of power and smoothness that turns an ordinary ride into something exceptional. When you push the throttle, the Q3 bites instantly. There’s no lag, no searching for grip. You’ll feel the lift right away — clean, decisive, and steady as the boat surges onto plane.

Once you’re running, the Q3 holds its line beautifully. The thin, high-rake blades carve through the water with minimal drag, giving you speed without the strain. It feels nimble yet controlled, with a smooth pull that keeps your momentum strong through turns and chop. Cruising feels almost effortless — the vibration is low, the response is crisp, and the sound is clean. It’s the kind of setup that makes you forget about your prop because everything just works.

When it’s time to open up, this Mercury propeller shows what it’s made of. The top-end speed competes with the fastest 3-blade props out there, but you’ll still get dependable grip and stability even when running light or heavy. And because it’s stainless steel, it’s tough — built to handle unexpected debris, long days on the water, and whatever conditions come your way. Season after season, it keeps its polish and its edge, so you can keep chasing those perfect runs.

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

If you want a prop that feels as refined as it is fast, the Q3 is a strong choice. Built with Mercury’s proven OEM precision, it offers the performance of a racing prop without the temperamental handling that often comes with one. You’ll get acceleration that feels instant, cruising that’s smooth and steady, and handling that’s responsive but forgiving.

Compared to other stainless options, the Q3 strikes a rare balance between power and efficiency. It’s not just for speed junkies — it’s for boaters who love control, comfort, and reliability in every condition. Whether you’re launching at dawn with a full load or stretching out for a long afternoon run, this prop delivers that confident, connected feel that makes boating a joy. Simply put, it’s one of those upgrades that makes a great boat even better.
