Why Choose an Aluminum Propeller?
Aluminum propellers like the Rubex 3 offer a balance between cost and performance. They’re more affordable than stainless steel counterparts, while still providing excellent handling and reliability. Aluminum is also lighter, which can contribute to better fuel efficiency and easier handling.
Additionally, aluminum propellers absorb more impact, meaning they’re less likely to damage your outboard motor’s drivetrain in case of underwater collisions. This makes the Rubex 3 an ideal choice for casual boaters, anglers, and weekend warriors.
How to Install the Rubex 3 Solas RH Propeller
Installing the Rubex 3 Solas RH Propeller is straightforward, thanks to the Rubex hub kit system. Here’s a step-by-step guide:
- Remove the old propeller by straightening the cotter pin and unscrewing the prop nut.
- Slide the old prop off and inspect the shaft for wear or debris.
- Install the Rubex hub kit according to the included instructions.
- Slide the Rubex 3 propeller over the hub and secure it with the nut.
- Insert a new cotter pin and bend to lock in place.
Always refer to your engine’s manual and follow proper torque specifications. Improper installation may cause damage or safety hazards.
Maintenance Tips
To ensure optimal performance and longevity of your Rubex 3 propeller, follow these maintenance tips:
- Inspect Regularly: Check for dings, cracks, and erosion before and after each trip.
- Lubricate: Apply marine-grade grease to the prop shaft during installation and periodically after use.
- Clean Thoroughly: Rinse with fresh water after saltwater use to prevent corrosion.
- Check Fasteners: Tighten propeller nuts to manufacturer specifications and inspect cotter pins regularly.
- Store Properly: If storing for long periods, remove the propeller and clean all components.
These small actions can significantly extend the life of your marine propeller and improve fuel efficiency.

Rubex 3 Propeller Troubleshooting Guide
If your Rubex 3 propeller isn’t performing as expected, consider these common troubleshooting tips:
- Low Top Speed: This could indicate improper pitch selection. A lower pitch increases acceleration but reduces top speed, and vice versa.
- Cavitation or Slippage: Ensure your hub is properly installed and check for bent blades.
- Excessive Vibration: Look for debris entangled on the shaft or prop damage.
Always address these issues quickly to avoid damage to your motor’s lower unit and reduce fuel waste.
Best Rubex 3 Solas RH Propeller Alternatives
If the 11.1 x 13″ isn’t ideal for your setup, consider other Rubex 3 models with different pitch options like 11.1 x 15” for higher top speed or 10.6 x 12” for improved acceleration. Stainless steel Rubex models are also available for higher performance needs, especially in saltwater environments.
However, for most boaters seeking a solid, budget-friendly, all-around performer, the 9311-111-13 hits the sweet spot.
Detailed FAQ Section
What engines are compatible with the Rubex 3 (11.1 x 13″) Solas RH Propeller?
The Rubex 3 9311-111-13 is compatible with a wide range of outboard motors, particularly 40–60 HP engines from Yamaha, Mercury, Evinrude, Suzuki, and Honda. Make sure to use the correct Rubex hub kit for your specific motor to ensure a secure fit and optimal performance. It’s best to consult your engine’s manual or speak with a marine professional before purchasing. Compatibility is typically based on shaft size and spline count, both of which must match.
How durable is the aluminum construction of this propeller?
While aluminum isn’t as hard as stainless steel, the Rubex 3 is made from a high-grade aluminum alloy that provides an excellent balance between weight and strength. It’s coated for corrosion resistance, making it suitable for both fresh and saltwater. With proper maintenance, it can last many seasons without significant wear, offering a cost-effective solution for recreational boaters. Minor dings can also be easily repaired compared to other materials.
What performance should I expect from a 13” pitch?
A 13” pitch generally provides a good compromise between acceleration and top speed. It’s suited for mid-range performance, making it ideal for activities like fishing, cruising, and light towing. If your boat feels sluggish out of the hole, consider switching to a lower pitch. Conversely, if your engine is over-revving, a higher pitch may help. Always ensure your RPM stays within the manufacturer’s recommended range for best engine health.
Can I install the Rubex 3 by myself?
Yes, installation is straightforward if you have basic tools. The Rubex interchangeable hub system makes prop changes simple. You’ll need a socket wrench, marine grease, and a replacement cotter pin. Always refer to the hub kit instructions and use proper torque when tightening the propeller nut. If unsure, a local marine service center can assist in under 30 minutes. DIY installation can save you money while teaching valuable boat maintenance skills.
What makes Rubex 3 better than traditional pressed-in hub propellers?
Traditional propellers often use a pressed-in hub that, once damaged, requires complete replacement. The Rubex 3’s interchangeable hub system allows you to replace just the hub, not the entire propeller. This saves money and time. It also simplifies maintenance and allows boaters to switch between different props with ease depending on boating activity or conditions. This feature alone makes it a favorite among both recreational and seasoned boaters.
Conclusion
The Rubex 3 (11.1 x 13″) Solas RH Propeller, 9311-111-13 is an outstanding choice for boat owners seeking performance, reliability, and value. With its lightweight aluminum build, smart hub system, and compatibility with multiple engines, it’s a product that delivers both functionality and flexibility. Whether you’re replacing a worn prop or upgrading for better performance, this propeller is an investment worth making. Don’t wait — improve your boating experience today.
