Mercury – Thunderbolt Propeller | High-Performance Series | High-Polished Stainless Steel | QS5005X

Overview

There’s a certain confidence that settles in when you run a propeller you truly trust. You feel it the moment you push the throttle and the boat lifts cleanly, ready for whatever the day brings offshore chop, winding channels, long runs back to the marina. A prop like the Thunderbolt becomes part of that quiet peace of mind, the kind boaters only earn through time on the water. When conditions change and the wind turns messy, it’s reassuring to know your prop will stay hooked up and steady.

Key Features

• High-polished stainless finish for lasting durability and smooth flow through the water
• Large 15.5-inch diameter paired with a 17-inch pitch
• Left-hand rotation design for select engines and dual-prop configurations
• Heavy-duty blade geometry engineered for strong lift and fast acceleration
• Designed to work with the correct Quicksilver hub system (check hub selection chart)

Engine & Boat Compatibility

• Ideal for Mercury V6 outboards requiring left-hand rotation
• Suitable for offshore fishing boats built for long, powerful runs
• Excellent on vee-bottom sport boats needing tight, predictable handling
• Strong match for cruisers and performance-driven recreational boats
• Works across a wide range of high-output marine setups

Performance & Practical Benefits

Once you set the QS5005X in motion, you’ll feel the stability that sets the Thunderbolt apart. Its larger diameter helps the boat grab more water, providing quick lift and cleaner transitions from idle to plane. Whether you’re turning around a buoy or trimming up to find that sweet cruising angle, the prop responds with a smooth, secure feel.

Left-hand rotation props are often paired with right-hand units in twin-engine applications, and this Thunderbolt handles that role with precision. It balances the boat, reduces steering torque, and helps keep your hull tracking true even in tight turns or crosswinds.

The stainless steel construction is more than just attractive—it resists flex, corrosion, and long-term wear that would weaken lesser props. That rigidity translates directly into better acceleration and consistent top-end performance, especially when you’re running in challenging conditions like heavy chop or strong tides. Over time, the durable finish helps maintain efficiency, giving you reliable thrust season after season.

Why Buy OEM

Genuine Mercury Marine parts are crafted for boaters who expect their equipment to work every time they head out. An OEM propeller like the QS5005X is engineered with exacting standards—balanced, tested, and shaped to deliver the performance Mercury engines were designed for. Aftermarket props might be cheaper, but they rarely offer the precise fit, smooth acceleration, and long-term durability that an OEM part delivers. Choosing this prop means choosing reliability, efficiency, and fewer surprises in the long run.
