Mercury Bravo Four S Propeller
The Bravo Four S forward-facing drive features contra-rotating props that grip undisturbed water to enhance maneuverability– even at lower tow sport speeds. The Bravo Four S drive is the ultimate solution for wakesurfing and other tow sports.
The Bravo Four S propellers deliver exception performance and reliability when paired with the Bravo Four S drive. Be sure to use in matched pitch sets only.
- Keep the conversation flowing with the Bravo Four S surf system. By running a four-blade prop in front of a three-blade prop, we’ve minimized cavitation, which reduces noise and vibration in the boat.
- Dual props rotating in opposite directions generate the thrust needed to propel surf boats that are heavily loaded with people and ballast, while providing a big boost in efficiency for all-day fun.

Ride the Wave: Bravo Four S Propellers
Mercury’s Bravo Four S propellers, engineered exclusively for the forward‑facing Bravo Four S drive, use a contra‑rotating four‑blade front and three‑blade rear configuration to “bite” undisturbed water and deliver razor‑sharp low‑speed maneuverability for wakesurfing and other tow sports.

Crafted as matched‑pitch stainless‑steel sets and integrated with Mercury’s SmartCraft® digital throttle, shift and Smart Tow® systems, the Bravo Four S surf package automatically tunes speed, surf tabs and ballast—giving surfers and drivers pro‑level performance at the push of a button.

The propellers were shipped quickly and work well on our Four Winns H2 with Bravo Four S. Works great for wake surfing.

Had to ordered new set of Bravo Four S propellers after damaging our last set. Props were clean and new in the Mercury box. Thank you.

Whether you’re looking for a replacement prop or want to optimize your boat’s speed, hole shot or efficiency, keep in mind that prop selection is about more than just pitch, diameter and number of blades. Performance is influenced by every aspect of a prop’s geometry, right down to cup, rake angle and edge shape.
