Performance Benefits

The Mercury Fury 4 Propeller is all about turning weight into confidence. When you’re loaded down with tackle, fuel, and livewell water, this prop doesn’t bog or fade — it lifts. The four-blade configuration grabs the water with authority, giving you solid traction and clean planing without the slip or drag you’d expect from a prop this strong.

Acceleration feels tight and responsive, not jerky or overworked. You’ll notice the Fury 4’s control most when cornering or trimming — it keeps your boat balanced and predictable even in chop or crosswinds. And that extra blade doesn’t just add stability; it gives you more lift, meaning faster holeshots and better performance when you’re carrying extra weight.

At high speeds, it feels composed and connected. No vibration, no wandering — just smooth, efficient movement that stays locked in. Thanks to the X7 stainless-steel alloy, the Fury 4 stays true under pressure, resisting flex and maintaining blade integrity run after run. And with the Performance Vent System (PVS), you can easily fine-tune your setup to your load, adjusting vent plugs for sharper acceleration or smoother transitions.

This is a prop designed to give you the edge when others slow down — a perfect balance of muscle, finesse, and dependability.

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

If you run a loaded bass boat and still expect lightning-fast response, the Mercury Fury 4 Propeller is the upgrade you’ve been waiting for. It’s built for anglers and performance boaters who want to go full throttle without giving up control.

What makes it special is how it blends power with poise. The Fury 4 delivers more lift, smoother handling, and tighter tracking when your boat’s heavy, yet still keeps pace with three-blade models in speed and acceleration. It’s the kind of prop that earns trust — not just for how it performs, but for how it feels.

Mercury’s engineering shows in every detail. The X7 stainless construction means years of reliable use, and the polish gives it a clean, professional look that matches its precision. It’s durable enough for saltwater, refined enough for freshwater tournaments, and responsive enough for anyone chasing perfect control.

If you want your boat to feel lighter, faster, and more balanced under load, the Fury 4 delivers — every throttle push, every turn, every run.
