Performance Benefits

The Mercury Bravo Four S 8M0167005 is all about control, thrust, and smooth power delivery. The front prop’s four-blade design grips the water with precision, generating lift and thrust that get heavy tow boats up on plane fast. Once you’re moving, the prop works in harmony with the rear prop to deliver strong, balanced propulsion — the kind that holds speed effortlessly even when loaded with passengers or gear.

You’ll notice how quiet and steady it feels. The contra-rotating system minimizes cavitation, reduces vibration, and cuts through turbulence. That means your boat stays smoother in turns, steadier at surf speed, and more responsive when adjusting for riders or wake shape.

Durability is another standout feature. Crafted from premium stainless steel, this prop resists corrosion, impact, and fatigue even in challenging conditions. The polished finish adds an extra layer of protection while keeping your setup looking sharp. It’s a prop built for years of confident pulls, smooth rides, and reliable starts — season after season.
