Volvo Penta Dual Rear Propeller Troubleshooting Guide
If you’re experiencing poor performance or unusual vibrations, your propeller might need attention. Here are common issues:
- Vibration: Likely due to bent blades or imbalance. Inspect for visible damage.
- Poor Acceleration: Could be caused by incorrect pitch or damaged rear prop.
- Overheating: A fouled or unbalanced propeller puts extra strain on the engine.
For troubleshooting, remove the prop, inspect thoroughly, and test rotation. If damage is visible, replacement is advised. A prop shop can also test blade pitch and balance for accuracy.
Expert Advice and Pro Recommendations
Marine professionals recommend the Volvo Penta stainless rear propeller for marine applications due to its proven durability and hydrodynamic efficiency. The dual rear setup, when paired correctly with a matching front prop, ensures stable acceleration and steering responsiveness, particularly at low RPMs.
Always ensure both front and rear props are matched in terms of material, pitch, and rotation direction. Misaligned props cause strain on the drive system and lower overall performance.

Detailed FAQ Section
How do I confirm if this propeller fits my Volvo Penta engine?
The Volvo Penta Dual Rear Stainless Steel 8551-139-15 propeller is designed specifically for dual-propeller setups, typically found on Volvo Penta DPH and DPR drives. You can confirm compatibility by checking your engine model’s manual or consulting your local Volvo Penta dealer. Always match the rotation (RH in this case) and pitch to the recommended specs for optimal performance.
How should I install a rear propeller in a dual setup?
Installation involves aligning the rear propeller with the splines on the shaft, using the correct tools, and torquing the nut as per Volvo’s specifications. Grease the shaft to prevent corrosion. It’s critical to ensure the propeller is matched to the front prop in terms of pitch and material. Improper installation can lead to vibration, noise, or damage to the lower unit.
What are the main benefits of stainless steel propellers?
Stainless steel propellers, like the 8551-139-15, offer superior strength, sharper hydrodynamic blade profiles, and resistance to impact and corrosion. Unlike aluminum props, they don’t deform easily and last longer in saltwater. This means fewer replacements, better performance, and long-term savings for serious boaters.
How often should I inspect my dual rear propeller?
It’s recommended to inspect your propeller before and after each trip. Pay close attention to signs of marine growth, bent blades, and loose nuts. At the end of the season, remove the prop, clean it, and inspect the shaft and seals. Proper inspection ensures that your propulsion system remains efficient and prevents unexpected failures on the water.
Is it worth upgrading to a stainless steel dual rear propeller?
Absolutely. Upgrading to a stainless steel dual rear propeller significantly improves durability, performance, and handling. While the initial cost is higher than aluminum props, the long-term benefits in terms of fuel savings, reduced maintenance, and smoother rides make it a valuable investment for both recreational and commercial marine use.
