Performance Benefits

You’ll feel this prop come alive the second you throttle up. The four-blade front design grabs undisturbed water and translates it into controlled thrust that builds evenly. It holds the boat steady on plane, making it easier to tow, surf, or just cruise without fighting vibration or chatter.

At low speeds, it feels predictable and quiet, giving you that refined sense of control when maneuvering close to the dock or lining up a perfect wake. Combined with its rear prop partner, it minimizes cavitation and maximizes thrust, turning your drive system into a smooth, powerful experience that’s as fun as it is efficient.

Why is this prop a strong choice vs. alternatives?

• Mercury OEM quality — precision-built for Bravo Four S systems
• Reliable and easy to maintain — stainless steel build resists corrosion and wear
• Cost-effective vs. stainless alternatives — strong long-term value and performance
• Versatile fit — ideal for surf, tow, and family cruiser setups
