It integrates flawlessly with Volvo Penta’s Dual Prop system, making it an essential choice for marine enthusiasts prioritizing reliability and performance.
Overview / What Is Volvo Penta RH Propeller for Marine
The Volvo Penta RH Propeller in stainless steel for the rear dual configuration is a specialized marine component designed to function as part of Volvo’s renowned DuoProp propulsion system. Unlike conventional single propeller systems, the DuoProp utilizes two counter-rotating propellers—front and rear—to significantly enhance acceleration, stability, and fuel efficiency.
Constructed from corrosion-resistant stainless steel, the 8551-139-23 propeller delivers extended durability against saltwater exposure and general marine wear. It features a 13.9-inch diameter and a 23-inch pitch, ideal for providing a balanced mix of speed and torque. The Solas RH rear prop is designed to rotate clockwise when viewed from the stern, completing the dual propeller assembly when paired with its LH front counterpart.
The propeller’s blade geometry is meticulously crafted using advanced CAD technologies, allowing for reduced vibration, improved grip in water, and optimized hydrodynamics. This makes it ideal for high-horsepower Volvo Penta applications in fishing boats, performance crafts, and even some commercial vessels.
Key Benefits of Solas RH Dual Rear Propellers
There are several compelling advantages to choosing the Solas RH Rear Propeller for Volvo Penta dual systems:
- Enhanced Performance: With dual propeller thrust, your boat experiences faster acceleration and better hold in the water.
- Greater Stability: The counter-rotating motion balances forces, reducing steering effort and boat yaw.
- Superior Corrosion Resistance: Stainless steel resists corrosion, making this propeller highly durable in saltwater.
- Reduced Cavitation: Efficient blade design minimizes water turbulence and prop slip.
- Fuel Efficiency: Optimized hydrodynamics contribute to lower fuel consumption, especially at cruising speeds.
These features ensure long-term savings and improved handling, especially when navigating in challenging water conditions or engaging in frequent long-distance trips.
How to Install Volvo Penta Dual Rear Propeller
Installing the Solas RH 8551-139-23 propeller is a relatively straightforward process when you follow manufacturer guidelines and safety protocols. You’ll need a propeller wrench, marine grease, gloves, and a torque wrench. Here’s a quick guide:
- Ensure the engine is off and remove the safety key to prevent accidental starting.
- Remove the existing rear propeller by loosening the prop nut and washer using a prop wrench.
- Clean the shaft and apply a marine-grade grease to prevent corrosion and ease future removal.
- Slide the new propeller into place, ensuring it aligns with the splines of the shaft.
- Reinstall the washer and torque the prop nut to the manufacturer’s specifications.
Always double-check for proper alignment and clearances. It’s also advisable to inspect the front propeller at the same time to ensure both parts are functioning optimally together.
Maintenance Tips
Maintaining your Volvo Penta Dual Rear Stainless Steel Propeller not only prolongs its lifespan but also ensures consistent performance on the water. Here are essential maintenance tips:
- Regular Inspection: After each boating session, inspect for debris, fishing line entanglement, or any signs of pitting or damage.
- Corrosion Control: Even though stainless steel is corrosion-resistant, routine freshwater rinses after saltwater exposure will prolong life.
- Lubrication: Periodically remove the propeller and apply marine-grade grease to the shaft to prevent seizing or rusting.
- Balance Check: If you experience unusual vibrations, have your propeller checked for balance or physical damage.
Keeping the propeller clean and properly installed ensures optimal fuel efficiency, speed, and handling over long-term use.
Performance Insights: Diameter and Pitch Impact
The 13.9-inch diameter and 23-inch pitch of this Solas RH propeller are carefully chosen for specific marine engine output and vessel weight. Larger diameters increase thrust at lower speeds, which is great for heavier boats, while higher pitch allows for greater speed at lower RPMs.
For Volvo Penta owners using dual props, this combination creates a perfect balance of low-speed torque and high-speed performance. You can enjoy smooth acceleration, improved fuel economy, and sustained top-end speeds. It’s particularly beneficial when towing water skiers or when cruising long distances offshore.
Expert Advice and Pro Recommendations
Marine professionals often recommend stainless steel props over aluminum due to their increased strength, better fuel economy, and resistance to flex under load. When selecting a replacement for your Volvo Penta rear prop, ensure it matches the model and pitch requirements of your front propeller for proper DuoProp synchronization.

Volvo Penta Propeller Troubleshooting
Experiencing reduced speed, poor acceleration, or abnormal vibrations? These are common signs that your propeller may need attention:
- Slow acceleration: Your propeller pitch may be too high or it may be damaged.
- Cavitation: This can be caused by improper installation or a worn-out hub.
- Unusual vibrations: A bent blade or debris entanglement could be the culprit.
Inspect your propeller and consult with an expert to determine if a replacement or rebalancing is needed. Maintaining the right pitch, diameter, and condition is essential for optimal marine engine performance.
Detailed FAQ Section
What is the difference between RH and LH Volvo Penta propellers?
RH (right-hand) and LH (left-hand) propellers rotate in opposite directions. In a Volvo Penta DuoProp setup, the front propeller typically rotates counterclockwise (LH) while the rear propeller rotates clockwise (RH). This counter-rotation stabilizes the boat and reduces torque steer, offering superior handling and performance. The Solas 8551-139-23 is an RH rear propeller that must be paired with the appropriate LH front prop for optimal results.
How do I know if this 13.9 x 23” propeller fits my engine?
Compatibility depends on your engine’s model, horsepower, and existing DuoProp configuration. The Solas RH 8551-139-23 is designed specifically for select Volvo Penta outboard and sterndrive models. You should consult your boat or engine manual or speak with a certified Volvo Penta technician before purchasing. Alternatively, contact our team at AllBoatSupplies for expert guidance within 30 minutes.
Can I replace just the rear propeller on a Volvo Penta DuoProp system?
Yes, but it is highly recommended to assess the condition and compatibility of both the front and rear propellers. Replacing just the rear propeller is acceptable if the front prop is in good condition and matches the rear in terms of pitch and material. Mismatched props can lead to imbalance, excessive vibration, and poor performance.
What’s the benefit of stainless steel over aluminum propellers?
Stainless steel propellers like the Solas RH 8551-139-23 offer greater strength, better durability, and improved performance. Unlike aluminum, stainless steel resists flexing under load, which means your boat maintains speed and handling even under heavy stress. They also provide better fuel economy and last significantly longer, especially in saltwater environments.
How often should I inspect or replace my Volvo Penta rear propeller?
We recommend inspecting your propeller every 25-50 engine hours or after every trip in rough conditions. Replacement should be considered if you notice pitting, cracks, or reduced performance. Most marine propellers last 3–5 seasons with regular use, but stainless steel variants tend to exceed that with proper care and maintenance.
Conclusion
The Volvo Penta Dual Rear Stainless Steel (13.9 x 23″) Solas RH Propeller, 8551-139-23 is a reliable, high-performance upgrade for any compatible Volvo Penta DuoProp system. From its premium stainless-steel construction to its expertly engineered blade geometry, this propeller is built to deliver exceptional speed, torque, and fuel efficiency. Whether you’re replacing a worn-out prop or optimizing your vessel’s performance, this Solas RH rear propeller is a top-tier solution for discerning boaters.
