Maintenance Tips
To extend the life of your B3 Bravo III Solas Rear Propeller, follow these best maintenance practices:
- Rinse After Use: Always rinse the propeller with fresh water after every saltwater trip to prevent corrosion and buildup.
- Inspect for Damage: Check the blades for nicks, dings, or cracks. Even small deformities can affect performance.
- Use Marine Grease: Apply quality marine grease to the prop shaft before installation to prevent seizing.
- Torque Specifications: Tighten the propeller nut using the manufacturer’s recommended torque settings.
- Regular Rotation: Rotate the props every few months if the boat is in storage to prevent seizing or shaft wear.
Proper care ensures that your Solas propeller remains efficient and safe for long-term use.
How to Install a Bravo III Rear Propeller
Installing the rear propeller on a Bravo III sterndrive is a relatively straightforward process, provided you follow safety guidelines and use the right tools. Here’s a basic step-by-step:
- Place the boat on dry land or trailer with the engine turned off and battery disconnected.
- Remove the existing rear propeller by loosening the propeller nut and washer.
- Inspect the prop shaft for damage, clean it, and apply fresh marine grease.
- Slide on the new Solas 1651-144-18 propeller ensuring proper alignment with the splines.
- Secure it with the washer and torque the prop nut to specs.
For safety and precision, consider using a torque wrench and consulting the manufacturer’s guide or technician if unsure.
Expert Advice and Pro Recommendations
Marine experts agree that replacing both front and rear props together—especially when upgrading to stainless steel—ensures the best performance. If your Bravo III system is still running a stock aluminum prop or only one upgraded blade, you’re missing out on potential gains in torque, fuel economy, and top speed.
Recommended Pairing: Combine the Solas 1651-144-18 rear with its matching front 4-blade Solas counterpart for balanced thrust and control.

Detailed FAQ Section
What boats are compatible with the Bravo III 1651-144-18 Solas Rear Propeller?
The Solas 1651-144-18 rear propeller is designed for boats equipped with Mercruiser Bravo III sterndrives, which feature a dual counter-rotating propeller system. Compatible boats typically include performance cruisers, sport boats, fishing vessels, and larger bowriders ranging between 20 to 35 feet. Compatibility also depends on your engine horsepower, gear ratio, and the matched front prop.
Can I use this rear propeller with a non-Solas front propeller?
While technically possible, it’s not recommended to mix brands or blade configurations on Bravo III dual prop systems. Doing so may result in imbalance, increased vibration, and decreased performance. Solas designs matched sets with synchronized pitch and geometry, so for optimal results, pair this rear 3-blade with the correct Solas front prop.
How do I know when to replace my propeller?
Signs it’s time to replace your propeller include:
- Noticeable vibration while running
- Loss of top speed or hole shot
- Visible dings, chips, or bent blades
- Excessive cavitation or ventilation
For Bravo III systems, it’s also essential to inspect both the front and rear props for wear simultaneously.
Is stainless steel really better than aluminum for marine props?
Yes, stainless steel offers superior strength, corrosion resistance, and efficiency compared to aluminum. For Bravo III propulsion systems, stainless steel props like the 1651-144-18 perform better under heavy loads and high speeds, last longer, and improve handling in rough conditions.
What pitch should I use if I’m upgrading from a different propeller?
The 18” pitch of the 1651-144-18 is ideal for boats looking for a balance between acceleration and cruising speed. If upgrading, try to match the pitch of your existing propeller unless you want to adjust RPMs. Lower pitch offers more acceleration; higher pitch offers more top speed. Consult with a marine prop technician to ensure ideal performance settings for your engine and boat weight.
Conclusion
The B3 – Bravo III – Mercruiser (14.4 x 18″) Solas Rear 3-Blade Propeller, 1651-144-18 is a trusted, high-performance upgrade for any boat using a Bravo III dual prop system.
