How to Install Volvo Penta Dual Rear Stainless Steel Propeller
Installing the Volvo Penta Dual Rear Stainless Steel (13.9 x 15″) Solas RH Propeller is straightforward for any experienced marine technician or hands-on boat owner. Always start by ensuring your engine is powered off and disconnected from the battery.
- Remove the prop nut and washers from your current setup.
- Clean the shaft thoroughly and inspect for wear or corrosion.
- Slide the new 8551-139-15 rear propeller onto the shaft, ensuring correct orientation.
- Use marine grease to lubricate the shaft and secure with the appropriate nut and locking mechanism.
- Tighten to the manufacturer’s torque specification and test rotation manually.
It’s recommended to use OEM-compatible installation kits and consult your Volvo Penta user manual for system-specific guidelines.
Maintenance Tips
Keeping your stainless steel propeller in optimal condition can drastically increase performance and extend its service life. Routine checks and preventative maintenance should be part of your boating habits.
- Inspect regularly: Look for dings, chips, or corrosion.
- Clean post-trip: Use fresh water after saltwater usage to prevent rust buildup.
- Lubricate hub: Apply marine-grade grease every 3–6 months or before long trips.
- Check alignment: Improper alignment can cause vibration and damage other components.
Also, replace worn-out bushings and ensure propeller blades are always balanced and free of deformities.
Performance Benefits of a Dual Prop System
The dual propeller configuration on Volvo Penta systems delivers unparalleled grip and directional stability. Unlike single props, the dual setup cancels out torque steer and offers faster planing, tighter turns, and smoother cruising at high speeds.
Using the Volvo Penta 8551-139-15 as your rear propeller guarantees the rear thrust matches the forward prop for balanced propulsion. This results in better fuel economy and overall reduced engine strain — a critical advantage for long-distance marine travel and watersports.
Expert Advice and Pro Recommendations
Marine experts consistently recommend stainless steel propellers like the Volvo Penta Dual Rear Solas RH 8551-139-15 for enthusiasts who demand performance and reliability. Especially in demanding environments like offshore or saltwater, where every knot of speed and gallon of fuel matters.
Pair this rear propeller with the appropriate front dual Solas model for best results. Always double-check engine compatibility and gear ratios before installation. If you’re uncertain, consult with marine supply professionals or authorized Volvo Penta dealers.

Detailed FAQ Section
What makes the Volvo Penta 8551-139-15 Solas propeller different from other propellers?
The Volvo Penta 8551-139-15 stands out for its dual-prop rear design, stainless steel construction, and compatibility with high-performance Volvo Penta drives. Unlike single propellers, this one is engineered to work in tandem with a front propeller, providing superior grip, speed, and maneuverability. It’s also corrosion-resistant, making it ideal for both freshwater and saltwater boating.
How do I know if this propeller fits my Volvo Penta system?
Check your engine’s model, drive type, and gear ratio. The 8551-139-15 is designed for use with specific Volvo Penta outboard dual prop systems. Cross-reference part numbers or consult a marine technician. Compatibility charts and OEM catalogs also help in verifying the exact fitment for your application.
What’s the difference between RH and LH propellers in a dual system?
RH (Right-Hand) and LH (Left-Hand) propellers spin in opposite directions to balance torque. In Volvo Penta dual systems, the front propeller typically spins in the LH direction while the rear prop (like the 8551-139-15) spins RH. This counter-rotation provides more stability, especially at high speeds or under heavy load.
How long does a stainless steel propeller last?
A quality stainless steel propeller, such as the Volvo Penta Solas 8551-139-15, can last over 5–10 years depending on usage, maintenance, and environmental exposure. Frequent inspections and proper storage increase longevity. Always avoid running aground or hitting debris, which could damage the blades.
Can I replace the propeller myself or do I need a technician?
If you’re familiar with marine equipment, replacing the propeller yourself is manageable using basic tools. However, precision is essential. Improper installation can lead to misalignment, vibrations, and reduced performance. If unsure, consult a certified Volvo Penta technician for installation.
