Overview / What Is B3 Bravo III Mercruiser Solas Propeller?
The B3 Bravo III Mercruiser Solas Propeller is a front-position, stainless-steel 4-blade prop designed for the Bravo III dual-propeller drive systems. With a size of 15.5 x 27 inches, it ensures balanced propulsion in both forward and reverse motion. This model (part number 1654-155-27) is engineered for durability, speed, and fuel efficiency across all boating environments.
Built using high-quality stainless steel and advanced casting methods, this Solas propeller offers excellent resistance to corrosion and impact. The 4-blade configuration enhances thrust and grip, especially useful during sharp turns or when towing. Precision pitch design ensures smoother rides and higher RPM efficiency, maximizing engine power and control.
Why Choose a 4-Blade Front Propeller?
A 4-blade propeller like the Solas 1654-155-27 provides superior hole shot, increased bow lift, and a smoother ride under heavy load. This design reduces cavitation, resulting in more stable acceleration and improved fuel economy. Additionally, the 4-blade structure offers excellent grip in choppy water or during tight maneuvers, making it a favorite among serious boaters.
This propeller’s front position pairs with a counter-rotating rear propeller, creating a balanced thrust and eliminating steering torque. As a result, it enhances handling, acceleration, and top-end performance of your Mercruiser-powered vessel.
How to Install B3 Bravo III Solas Propeller
Installing the B3 Bravo III Solas propeller is straightforward but requires basic tools and attention to safety. Here are the general steps:
- Remove the old front propeller by unscrewing the lock nut using a prop wrench.
- Inspect the shaft for wear, damage, or fishing line debris.
- Grease the propeller shaft lightly before placing the new Solas propeller.
- Align the splines correctly and slide the prop onto the shaft.
- Secure it with the original lock nut and torque it as per manufacturer specifications.
Important: Always refer to your specific Mercruiser manual for torque settings and any model-specific steps.

Bravo III Propeller Performance: Speed vs Torque
Choosing a 27” pitch on a Bravo III propeller is ideal for high-speed applications and boats with adequate engine torque. This Solas 1654-155-27 propeller prioritizes top-end performance while maintaining acceptable hole shot capability. For heavier boats or towing needs, you may consider a lower pitch (e.g., 25″) for better low-end torque.
Bravo III systems inherently balance torque and handling thanks to their dual-prop design, but pairing them with a quality Solas propeller fine-tunes this balance to your boating style.
Troubleshooting Common Bravo III Propeller Issues
If you’re facing vibration, decreased RPM, or cavitation, the problem could stem from improper propeller fitment or wear:
- Vibration: Check for bent blades or unbalanced props.
- RPM Drop: Pitch may be too high for your engine—consider switching to a 25” pitch variant.
- Prop Slippage: Ensure the prop is tightly secured and the keyway isn’t damaged.
Correct diagnosis and proactive maintenance help keep your B3 Bravo III Mercruiser Solas Propeller running efficiently season after season.
Detailed FAQ Section
What boats are compatible with the B3 Bravo III Solas Front Propeller?
This propeller is designed for Mercruiser Bravo III dual-prop outdrive systems. It fits a wide range of boats including cruisers, sport boats, and high-performance vessels using Bravo III lower units. As long as your engine supports the 15.5 x 27″ front prop setup, this model will work seamlessly. For boats under heavy load or used for towing, a lower pitch version may be more suitable.
How do I know if I need to replace my current propeller?
If you experience excessive vibration, sluggish acceleration, reduced fuel efficiency, or visible blade damage, it’s time to inspect and potentially replace your propeller. Minor dings can sometimes be repaired, but deep cracks, warping, or bent blades often require a full replacement. This is where the B3 Bravo III Solas 1654-155-27 shines with its strong stainless steel and performance geometry.
Is stainless steel really worth it over aluminum?
Yes, stainless-steel propellers like the Solas 1654-155-27 offer enhanced durability, better performance, and longer life than aluminum counterparts. They handle higher RPMs and more torque without flexing or breaking. If you boat in saltwater or encounter floating debris, stainless steel is a far superior long-term investment due to its resistance to corrosion and damage.
Can I install this propeller myself, or do I need a technician?
Most boaters with basic mechanical knowledge and tools can install this Solas propeller at home. All you need is a prop wrench, marine grease, and the ability to follow torque specifications. However, if you’re unsure or upgrading from a different pitch, consulting a technician can ensure optimal fitment and performance tuning for your Bravo III drive.
How does pitch affect my boat’s performance?
Pitch refers to the distance your propeller would move in one revolution if it were moving through a soft solid (like a screw through wood). A 27” pitch like the Solas 1654-155-27 allows your boat to travel further per rotation, favoring higher speeds. However, it reduces low-end torque, making it less ideal for heavy towing or slow acceleration. Choose the right pitch based on how you use your boat—speed or load-based.
Conclusion
The B3 – Bravo III – Mercruiser (15.5 x 27″) Solas Front 4-Blade Propeller is a top-tier solution for serious boaters seeking performance, efficiency, and durability. With premium stainless steel construction, advanced blade geometry, and compatibility with Mercruiser Bravo III systems, this propeller delivers consistent performance in both calm and challenging waters.
