Mercury – Thunderbolt Propeller | High-Performance Series | High-Polished Stainless Steel | QS5007X

Overview

There’s a certain comfort that comes from knowing your boat will respond the moment you ask it to. It’s that steady confidence you feel when the engines come alive, the hull lifts, and the propeller grabs hold of the water like it’s meant to. The Thunderbolt propeller carries that feeling from the first throttle push to the last mile of the day. Whether you’re running a big offshore spread or cruising home after a long afternoon, it’s reassuring to know you’re relying on a prop engineered to stay smooth, stable, and predictable.

Key Features

• Three-blade stainless steel propeller built for high-horsepower marine performance
• High-polished finish for reduced drag and long-lasting corrosion resistance
• Large 15.3-inch diameter paired with a 19-inch pitch
• Left-hand rotation for compatible twin-engine setups and specific performance applications.
• Bold blade geometry designed to maintain bite, lift, and thrust at elevated speeds
• Works with Quicksilver hub systems (refer to hub selection guidelines for proper fit)

Engine & Boat Compatibility.

• Ideal for Mercury V6 outboards requiring a left-hand rotation propeller
• Suitable for offshore fishing boats running twin-engine configurations
• Excellent match for vee-bottom sport boats and fast-cruising hulls
• Reliable choice for performance-oriented boats seeking improved handling and lift.
• Compatible with a wide range of high-output marine powerplants

Performance & Practical Benefits

The Thunderbolt QS5007X delivers the kind of performance you can feel immediately—strong grip when you accelerate, smooth bite when you carve into turns, and a steady, confident ride at high speed. Its large diameter creates powerful lift, helping your boat reach plane quickly even with heavier loads or choppier water.

The stainless steel blades are engineered to resist flex, which means they hold their exact shape even when your engine is pushing hard. That rigidity translates into crisp acceleration, predictable steering, and a tighter connection between throttle and boat response. And because the blades cut cleanly through the water, you’ll often notice smoother cruising and more efficient fuel burn over long runs.

When the conditions get sloppy, the Thunderbolt keeps its composure. It holds onto the water with a secure, almost locked-in feel that gives the helm a natural steadiness. It’s the kind of prop that rewards experienced captains and gives newer boaters the confidence to run farther and smoother.

Why Buy OEM

Choosing an OEM Mercury Marine part means you’re getting a prop designed, tested, and balanced specifically for Mercury engines. That level of precision matters—especially with high-horsepower applications where even small variations can affect performance or longevity. Aftermarket props may claim compatibility, but they rarely match the balance, metallurgy, and engineering that Mercury builds into every Thunderbolt. With OEM, you’re choosing reliability, durability, and the assurance that your engine is performing exactly as designed.
