Performance Benefits

The Mercury Trophy Plus 8M0151392 is designed for serious performance. From the moment you open the throttle, it digs in with purpose, lifting the bow and getting you on plane fast — no hesitation, no slip. Its four-blade geometry keeps the prop locked to the water, giving you excellent traction and control through turns, even at aggressive trim angles.

At cruising speed, the prop maintains a smooth, predictable feel, keeping your hull free and fast across open water. The added blade surface helps hold lift at high engine heights, giving you both speed and stability — a must for bass and flats boats running light and high.

Mercury’s Performance Vent System (PVS) lets you customize your hole shot — open the vents for quicker launches or close them for firmer grip under load. This adjustability gives you total control over your setup.

Crafted from stainless steel, the Trophy Plus resists flexing and corrosion, transferring every bit of torque into forward motion. The result is smoother handling, better acceleration, and long-lasting reliability in any environment.

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

The Mercury Trophy Plus QS8M0151392 stands out because it’s built for boaters who want performance they can feel. Its four-blade design offers the perfect balance of lift, grip, and speed, while its stainless steel construction ensures unmatched strength and durability over time.

Compared to aluminum props, it delivers sharper response, higher efficiency, and greater stability at speed. Its tunable vent system also gives it the edge in adaptability — you can fine-tune acceleration and handling based on your load, water conditions, or engine setup.

Whether you’re chasing top-end speed on tournament day or cruising for pleasure, the Trophy Plus keeps you connected, confident, and in control. It’s Mercury engineering refined to perfection — strong, smooth, and ready to perform season after season.
