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

If you’ve been running a standard prop and think you’ve seen what your engine can do, the Quicksilver Q4 Stainless Steel Propeller might surprise you. It combines the lift, grip, and acceleration of a four-blade with the speed and efficiency of a three-blade, giving you the best of both worlds.

Backed by Mercury OEM engineering, the Q4 is precision-built for boaters who care about real-world performance — not just numbers on a spec sheet. It’s as versatile as it is reliable, performing just as well on a calm lake as it does in choppy offshore conditions. Whether you’re powering through a tight corner or running full throttle across open water, this prop feels responsive, balanced, and ready for whatever’s next.
