Mercury Fury 4 Propeller

Mercury Fury 4 Propeller

Summary: The Mercury Fury 4 Propeller is engineered from the ground up for tournament‑loaded bass boats, combining a four‑blade, high‑progressive‑rake design with an eight‑hole Performance Vent System (PVS) to deliver unparalleled mid‑range acceleration, superior lift, and rock‑steady handling in the roughest water. Constructed of Mercury’s proprietary X7 stainless‑steel alloy, the Fury 4 not only endures the demands of heavy‑load applications—fuel, batteries, tackle, and livewell full—but also outpaces its three‑blade Fury counterpart by up to 1 mph under tournament weights. Customizable PVS venting (two holes per blade) lets anglers fine‑tune hole‑shot characteristics for any engine, gear ratio, or hull setup. Below is a breakdown of its key features and performance advantages.

Performance Highlights

1. Superior Mid‑Range Acceleration Under Load

• Thanks to its four‑blade lift and optimized PVS tuning, the Fury 4 delivers unmatched mid‑range throttle response, getting heavy tournament bass boats on plane faster than any other propeller
• Field tests report mid‑range RPM gains of 100–150 rpm over comparable three‑blade designs, translating to quicker hole‑shots and stronger acceleration through chop and wakes

2. Exceptional Holding in Rough Water

• The Fury 4’s blade shape and cup geometry “grab” the water for rock‑steady handling in turbulent conditions, minimizing yaw and side‑to‑side rocking when driving through waves.
• Anglers consistently praise its ability to maintain course and speed even in 2–3‑foot chop, ensuring reliable performance when every second counts en route to the weigh‑in.

Design & Construction

X7 Alloy & Four‑Blade Geometry

• Mercury builds the Fury 4 from its proprietary X7 alloy, offering a 30 percent increase in strength and four times the durability of conventional stainless steel—ideal for the stresses of tournament‑loaded boats.
• The high‑progressive‑rake, four‑blade profile generates extra lift and optimizes blade entry angle, significantly enhancing mid‑range thrust and reducing ventilation under heavy load.

Performance Vent System (PVS)

Each Fury 4 blade features two forward‑mounted PVS holes (eight total) equipped with Mercury’s solid plugs, allowing on‑water tuning of exhaust venting to perfect hole‑shot response — improving plane‑up times without sacrificing bite.

Tournament‑Load Bass Application

• Designed for outboards from 90 HP CT through 350 HP, the Fury 4 is purpose‑built for today’s high‑powered bass rigs—fully loaded with fuel, electronics, batteries, tackle, and a brimming livewell.
• Under heavy loads, the Fury 4 consistently outperforms the three‑blade Fury by up to 1 mph in top‑end speed tests, making it the world’s fastest propeller for tournament‑weighted setups.

Fury 4 vs Fury 3-Blade: A Side-by-Side

Feature	Fury 3-Blade	Fury 4-Blade
Mid-Range Acceleration	Strong, but limited under heavy load	Unmatched acceleration; higher RPM
Rough-Water Handling	Good	Superior holding; minimized yaw
PVS Customization	Single-hole, standard tuning	Eight-hole system (2 per blade)
Top-End Speed (Tournament Load)	Baseline speed	+1 MPH over Fury 3 under load

Conclusion

For competitive bass anglers demanding every ounce of performance from a fully loaded tournament boat, the Mercury Fury 4 Propeller is the definitive choice. Its advanced four‑blade design, robust X7 alloy construction, and fully customizable PVS venting deliver rapid mid‑range acceleration, steadfast control in rough water, and a proven top‑end advantage over three‑blade alternatives. Whether you’re chasing early‑morning limits or racing to the weigh‑in, the Fury 4 puts you—and your catch—on plane faster, smoother, and more reliably than ever before.
