Bravo I® FS

  • Compared to a three-blade propeller, the shortened barrel of the four-blade Bravo FS provides the same impressive bow lift, with a slight degree of added stern lift.
  • In light to medium chop, the Bravo FS offers a smoother ride.
  • In rough conditions, four blades improve the angle of attack with the motor trimmed in. This means the boat can stay on plane at lower speeds.
  • Greatly improved hole shot and midrange fuel economy
  • Four blades allow for higher running heights and improved efficiency over a three-blade thanks to less drag from the gearcase in the water.

With the introduction of the four-blade Bravo FS, bass, multispecies, bay boat, and center-console applications have realized much quicker planing compared to three-blade propellers. In addition, the Bravo FS provides a much smoother ride by improving the angle of attack. By switching to a Bravo FS, the engine can be raised as much as an inch, getting the most performance of any engine application and improving the driving experience. For some stepped hulls, the Bravo FS offers more bow lift than the Rev 4, improving ride quality because the boat rides on the steps correctly.

The Mercury® patented Performance Vent System® (PVS) enables operators to dial-in their propeller for peak planing performance. The PVS® system works in concert with robust blades that are hand blended and balanced by our propeller lab artisans. The tuned exhaust tube minimizes stern lift for enhanced bow lift, handling and overall boat performance.

A majority of Mercury Verado®, Mercury Pro FourStroke and MerCruiser® sterndrive applications will use the Bravo I FS with all four vent holes plugged with solid PVS fittings. Larger, heavier multiple engine applications may benefit by taking one or two fittings out for improved planing. The Bravo I FS may be used with multiple OptiMax® outboard applications as well. A majority of those will use the Bravo I FS with all four vent holes opened for improved planing performance.

To maintain similar engine operating rpm in single engine applications, switching from a Tempest® Plus to the Bravo I FS would require a 1” increase in pitch. A switch from the
Fury® and Revolution 4® to the Bravo I FS would require a 2” increase in pitch.
