How to Install the Rubex 3 Propeller
Installing the Rubex 3 propeller for marine engines is a straightforward process. It is designed with the Rubex interchangeable hub system, which allows the propeller to be easily mounted on the prop shaft using basic tools. Here’s how to get started:
- Ensure the engine is turned off and out of gear.
- Remove the cotter pin, castle nut, and washer from the current propeller.
- Slide the old propeller off the shaft carefully.
- Install the Rubex hub kit inside the new propeller (sold separately if not already installed).
- Slide the new Rubex 3 propeller onto the shaft, aligning it properly.
- Reinstall the washer, castle nut, and cotter pin securely.
Always refer to your engine’s user manual for torque specifications and safety protocols.
Rubex 3 Propeller Performance in Real Boating Conditions
One of the standout aspects of the Rubex 3 9311-111-13 aluminum propeller is how it performs under varying marine conditions. Whether navigating calm inland waters or choppy offshore waves, the propeller remains balanced and efficient. Thanks to its 3-blade geometry, acceleration is quick, and planing speed is reached much faster compared to stock props.
Fuel consumption is also noticeably reduced, especially at cruising RPMs, due to the hydrodynamic blade design. Less drag means the engine works less to achieve the same result — a benefit that pays off in fuel savings over time. Ideal for mid-sized fishing boats, pontoon boats, and smaller speedboats, it’s a propeller that delivers consistency without compromise.
Maintenance Tips
Proper maintenance is essential to prolong the life of your Rubex 3 propeller. Even though it is corrosion-resistant, environmental exposure can still affect performance. Here are some tips:
- Regular inspection: Check for dings, cracks, or signs of cavitation.
- Grease the shaft: Prevents seizing and corrosion between prop and shaft.
- Rinse with fresh water: After every use in saltwater to remove salt buildup.
- Check torque settings: Ensure prop nut is tight and cotter pin is not rusted or bent.
- Store in a dry place: When not in use, especially in winter months.
Regular care ensures optimal thrust and keeps your boating experiences smooth and safe.

Rubex 3 Propeller Troubleshooting Guide
Encountering issues with your Rubex 3? Here are common problems and solutions:
- Vibration: Could be due to a bent blade or misaligned hub. Inspect blades carefully.
- Slipping: This indicates a worn or improperly installed hub. Replace or reseat the hub.

Always carry backup tools and a spare prop if heading out for longer journeys.
Detailed FAQ Section
Is the Rubex 3 (11.1 x 13″) Propeller compatible with Yamaha outboards?
Yes, the Rubex 3 (11.1 x 13″) Solas RH Propeller, model 9311-111-13, is compatible with a wide range of Yamaha outboards, especially models between 25 to 70 HP. To ensure full compatibility, you’ll need the corresponding Rubex hub kit for Yamaha. This modular design allows the same propeller to be used across various engines by swapping out the hub.
What makes this propeller better than OEM options?
The Rubex 3 outperforms many OEM aluminum propellers in both thrust and durability. Its unique blade shape and interchangeable hub system offer better acceleration, smoother cruising, and longer-lasting performance. Compared to OEM props, you get more flexibility and less vibration. Additionally, the Solas engineering ensures better fuel efficiency and handling at high speeds.
How do I choose the right pitch for my engine?
Pitch refers to the distance a propeller moves in one revolution. The 13” pitch on this Rubex 3 is great for mid-range performance. If your boat struggles to reach planing speed or feels sluggish, try a lower pitch. If you want higher top-end speed and your engine isn’t over-revving, you could test a higher pitch. Always consult with a marine expert before making pitch changes, as incorrect pitch can harm your engine.
Is the Rubex 3 suitable for saltwater use?
Yes. Though made of aluminum, the Rubex 3 is treated with anti-corrosive coatings that resist saltwater oxidation. However, post-use maintenance is crucial. Always rinse the propeller with fresh water and apply marine grease on the shaft to prevent long-term corrosion. For extreme saltwater usage, stainless-steel options may also be worth considering.
What hub kit do I need for this propeller?
The Rubex 3 uses Solas’ proprietary interchangeable hub system. You’ll need to purchase a Rubex hub kit that corresponds with your outboard motor brand (Yamaha, Mercury, Honda, Suzuki, etc.). These kits come with a bushing, thrust washer, and hardware to secure the propeller. One of the benefits of this system is that if you change boats or engines, you can reuse the same prop by simply changing the hub.
Conclusion
When it comes to reliability, performance, and versatility, the Rubex 3 (11.1 x 13″) Solas RH Propeller, 9311-111-13 stands out in the marine propeller market. Whether you’re upgrading from stock or replacing a damaged unit, it provides a noticeable boost in handling, fuel efficiency, and durability. With proper maintenance and the right hub kit, it’s a long-term investment in smoother, safer boating.
