Solas Bravo Three Rear Propeller 14.4x20 (3-Blade RH) Stainless Steel

The Solas Bravo Three rear propeller (Part No. 1651-144-20) is a 3-blade stainless steel prop designed for the rear position in MerCruiser’s twin-prop Bravo 3 sterndrive system. In Bravo 3 drives, there is a front and a rear propeller working in tandem – the rear prop typically rotates clockwise (right-hand) while the front rotates counter-clockwise (left-hand). This rear prop, measuring 14 3/8 x 20 inches, is responsible for a significant portion of the overall thrust and particularly contributes to reverse power. Its three blades have a relatively steep pitch (20″) since they operate in the accelerated slipstream from the front prop – a design that maximizes the efficiency of the dual-prop setup. Constructed entirely of stainless steel, the propeller withstands the high torque and speeds associated with powerful engines (Bravo 3 drives are often mated to 220+ HP V6 and V8 engines). Usage and Recommendations: This rear prop is used in conjunction with its matching front prop (usually a 4-blade, left-hand rotation prop of the same pitch) on a Bravo 3 drive. The Solas ~14.4x20RH is a direct equivalent replacement for the original rear prop of 20″ pitch sets (for example, corresponding to Mercury/MerCruiser “Bravo Three” rear propellers for 20 pitch). When upgrading or replacing, always ensure the front and rear propellers are a pitch-matched set and proper blade combination – this model should be paired with a 4-blade 16x20L front prop (Solas Part No. 1654-160-20). The combination of stainless steel and precision-cast blades gives your boat better “grip” on the water during rapid acceleration, reduced vibration, and virtually eliminates the feeling of the boat rolling to one side when throttling up (torque steer). Additionally, reverse thrust is greatly improved – when you engage reverse, the dual prop system pulls the boat backwards with authority and control, making docking much easier. Installation: The Solas rear prop comes with an integrated hub and mounts on the inner (rear) prop shaft of the Bravo 3 drive. Use the original MerCruiser locking mechanism (cone and nut) and tighten to the recommended torque. After installation, verify that the propellers spin freely and that the clearance between the front and rear props is correct – they should not contact each other. With this Solas prop in place, your Bravo 3 system will regain or even exceed its factory performance, all at a more affordable cost compared to OEM options.

• Part of a matched Bravo 3 set – intended to work in unison with a front prop of the same pitch; they must be used as a pair for optimal performance (e.g., 20P front + 20P rear combination)
• Faster acceleration and planing – the 3-blade rear + 4-blade front prop combo delivers immediate power, shortening the time needed to get the boat on plane, even under heavy load
• Improved reverse thrust and maneuvering – the twin-prop system with this rear prop generates significant backward pull, allowing precise control in docking and quick stopping power
• High strength & corrosion resistance – stainless steel construction endures prolonged saltwater use and the high forces from powerful engines, while maintaining blade shape under stress
• Balanced and smooth operation – Solas crafts these props to high precision, ensuring balance between the front and rear prop; this results in reduced vibrations, quieter running, and less long-term wear on the drive
