A monthly inspection schedule can help you catch minor issues before they become costly repairs.
How to Install the Volvo Penta Dual Rear Propeller
Installing the 8551-139-15 Solas RH Propeller is a straightforward process if you follow these steps carefully:
- Disconnect the battery and ensure the engine is off.
- Remove the old rear propeller using a prop wrench.
- Clean the shaft and apply marine grease.
- Align and slide the new Solas RH propeller onto the shaft.
- Secure with washer and nut, torquing to specifications.
- Spin the propeller manually to ensure smooth movement.
Refer to your engine’s manual or consult with a marine technician if unsure about any step.
Troubleshooting Common Propeller Issues
Even the best propellers encounter performance hiccups. Here’s how to diagnose and address common problems with your Solas stainless steel dual rear prop:
Cavitation
Often caused by blade damage or incorrect installation, cavitation manifests as a drop in RPM and speed. Check for dings, pitting, and proper alignment.
Vibration
High-speed vibration usually stems from imbalanced blades or marine debris. Remove the propeller and inspect for signs of imbalance or fouling.
Overheating
This could be linked to excessive load or a mismatch between front and rear props. Ensure your dual setup is correctly matched and your engine isn’t overloaded.
Expert Advice and Pro Recommendations
Marine professionals recommend pairing this rear propeller with its designated Solas front counterpart for full performance potential. The Volvo Penta Dual Rear Stainless Steel Solas RH Propeller performs best on boats that demand precise handling, strong torque, and fuel-efficient cruising.

Detailed FAQ Section
Is the Solas 8551-139-15 propeller compatible with all Volvo Penta DuoProp drives?
No, it is specifically designed for the DPS drive series. While it may look similar to other props, the internal spline and blade profile are engineered for DPS configurations only. Always consult your engine manual or speak with a marine technician to ensure compatibility. Incorrect installation can result in poor performance and long-term damage to the gear case or propeller hub.
How does the stainless steel material affect performance and durability?
Stainless steel offers significantly higher strength than aluminum, allowing for thinner blades and better hydrodynamics. It resists corrosion better—particularly in saltwater environments—and maintains its shape at high RPMs. The result is increased longevity, consistent performance, and reduced long-term cost even if the upfront price is higher. For serious boaters, the upgrade to stainless steel is a worthwhile investment.
What is the advantage of the dual-propeller (DuoProp) system?
DuoProp systems use two counter-rotating propellers—front and rear—to balance the torque, improve handling, and maximize propulsion. The result is faster acceleration, better grip in turns, and improved fuel efficiency. The rear Solas RH propeller in this case plays a crucial role in working with the front LH prop to deliver this balanced thrust and directional control. It’s ideal for heavy loads or high-speed applications.
How do I know if my propeller needs replacing?
Signs include unusual vibration, difficulty getting on plane, reduced fuel efficiency, and visible physical damage. If your current prop has significant dings, corrosion, or wear, performance will drop and engine stress may increase. Propeller replacement every few seasons is recommended for active boaters. Be proactive rather than reactive—especially before long trips.
Can I install the propeller myself, or do I need a professional?
If you have basic mechanical skills, the right tools (prop wrench, torque wrench), and the manufacturer’s manual, you can perform the installation at home. Just be sure to inspect both the front and rear propellers for correct matching. If unsure, or if you’re dealing with damage or corrosion, it’s safer to consult a marine technician to avoid costly mistakes. Installation typically takes under 30 minutes with preparation.
Conclusion
The Volvo Penta Dual Rear Stainless Steel (13.9 x 15″) Solas RH Propeller, 8551-139-15 is a robust and high-performing solution for modern marine propulsion systems. Designed for use with Volvo Penta DPS drives, it offers superior durability, performance, and fuel economy.
