The Bravo Four S® forward-facing drive features contra-rotating props that grip undisturbed water to enhance manoeuvrability – even at lower tow sport speeds. Integrated with SmartCraft® digital features, the Bravo Four S drive is the ultimate solution for wakesurfing and other tow sports.
Mercury crafted five prop sets specifically for the Bravo Four S drive’s contra-rotating configuration. They are optimised to enhance grip, reduce noise and boost efficiency.
A complete surf system
We have simplified driving for tow sports by integrating the drive with a VesselView® display and the Smart Tow® system. All you do is select the activity, speed and wake you want. The system makes the necessary adjustments to deliver exactly what you asked for every time.
Standard with Bravo drives, the MerCathode® system is a powerful electronic corrosion inhibitor that automatically and constantly fights back against galvanic corrosion.
You can do more with your surf boat thanks to the steerable, trimmable drive. Use the trim to dial in the wake for surfing or adjust the running attitude while cruising. Or just raise it up to join your friends on the sandbar.
Premium, smooth Digital Throttle & Shift (DTS) controls come as standard with the Bravo Four S drive and enhance every on-water activity, whether docking at the marina, cruising across the lake or laying out the perfect wake.
Low speed control
Bravo Four S gear ratios are optimised for getting big, heavily loaded surf boats on plane at low speeds and keeping them there for an ideal surfing experience.
We have simplified service with features that minimise maintenance and make routine tasks easier, leaving you more time for adventure.
Tough conditions? Bring it on. Mercury drives are built with proprietary alloys and superior corrosion-preventive finishes developed specifically for marine applications.
