How to Install the B3 Bravo III Mercruiser Propeller
Installation of this Bravo III rear propeller is relatively straightforward for seasoned boaters or professionals, but there are key steps and safety guidelines to follow:
- Ensure the engine is turned off and key is removed.
- Use a prop wrench to remove the propeller nut from the current rear prop.
- Slide the old propeller off the shaft carefully, checking for fishing lines or debris.
- Grease the splines with marine-grade grease.
- Slide the new Solas 1651-140-26 propeller onto the shaft.
- Reinstall the prop washer and nut, then torque to manufacturer specifications.
Warning: Never overtighten the prop nut, and always double-check alignment of the key and spline during installation to avoid damage.
Maintenance Tips
Regular maintenance of your Bravo III Solas propeller can significantly extend its lifespan and maintain its performance. Here are some essential care tips:
- Inspect for dings, cracks, or deformation after every trip.
- Remove and clean the propeller shaft at least every 50 hours of operation.
- Apply anti-seize marine grease to the shaft to prevent corrosion and seizing.
- Check the prop nut torque periodically and ensure the cotter pin or locking tab is secure.
- Flush with freshwater after saltwater use to remove residue and salt deposits.
Neglecting routine care can lead to issues like cavitation, vibration, and even lower unit damage. Investing a few minutes after each ride can save you hundreds in repairs.
Bravo III Propeller Performance vs. Other Prop Types
Compared to single-prop systems, Bravo III dual-prop setups offer enhanced thrust and acceleration thanks to the counter-rotating blades. This rear Solas 3-blade propeller plays a critical role in:
- Reducing cavitation under load
- Providing tighter turning radius at low speeds
- Stabilizing boat trim and lift during high-speed cruising
For heavy-duty marine applications like towing or offshore cruising, the Bravo III setup outperforms single props in control and efficiency. Combined with Solas craftsmanship, the B3 Bravo III Mercruiser propeller for marine delivers superior ride quality.
Expert Advice and Pro Recommendations
Marine mechanics and performance boaters recommend pairing the rear 3-blade with a 4-blade forward prop for best results. This setup balances acceleration and top-end efficiency while minimizing prop slip. If your propeller is worn or mismatched, you’ll experience sluggish hole-shots, poor fuel economy, and steering lag.
It’s essential to match the pitch and rotation to your boat’s engine rating. The 14 x 26″ Solas is a common mid-to-high pitch suitable for V6 and V8 MerCruiser engines.

Detailed FAQ Section
What boats are compatible with the B3 Bravo III Mercruiser 14 x 26” propeller?
This propeller fits MerCruiser Bravo III sterndrives, commonly found on powerboats, cabin cruisers, and some high-performance fishing vessels. If your boat uses the Bravo III outdrive system and your engine operates within the RPM range that suits a 26-pitch prop, then the Solas 1651-140-26 will be a perfect rear match. Compatibility also depends on your forward prop size and total boat load. Always consult your owner’s manual or dealer for precise fitment.
How do I know when it’s time to replace my Bravo III rear propeller?
Signs include visible blade damage, unusual vibrations during acceleration, poor fuel efficiency, and difficulty in steering or reverse thrust. A worn or bent blade can cause cavitation and reduce overall propulsion efficiency, which in turn puts strain on your engine and transmission. Periodic inspections and preventive replacement are advised every 200–300 hours of use, depending on water conditions.
Can I install the Solas Bravo III rear propeller myself?
Yes, if you have basic marine mechanical knowledge and the proper tools. You’ll need a prop wrench, marine grease, and a torque wrench. Always follow manufacturer guidelines during installation and torque the nut to spec. If you’re unsure, hiring a certified marine technician ensures proper installation without voiding any warranties.
What is the difference between a 3-blade and 4-blade Bravo III propeller?
The 3-blade rear prop like the Solas 1651-140-26 is designed for higher top speed and better fuel economy. The 4-blade forward prop complements it by offering better grip and acceleration at takeoff. Together, they create a balanced performance profile. Some boaters prefer dual 4-blade setups for towing or heavier boats, but this may reduce top-end speed slightly.
Is the Solas 1651-140-26 suitable for saltwater use?
Absolutely. This propeller is crafted from high-chromium stainless steel, providing excellent corrosion resistance in saltwater environments. Just be sure to rinse with freshwater after every outing, and apply marine grease to the shaft regularly. With proper care, this prop can last multiple seasons, even in aggressive saltwater conditions.
