Rubex 3 (10.5 x 11″) Solas RH Propeller, 9211-105-11 for Boats & Marine Engines

Overview / What Is Rubex 3 Solas RH Propeller?

The Rubex 3 Solas RH Propeller, 9211-105-11, is a three-blade aluminum propeller designed for outboard engines requiring right-hand rotation. With a 10.5-inch diameter and 11-inch pitch, it delivers balanced performance in various marine applications, from recreational boating to light commercial tasks. Manufactured by Solas — a trusted name in marine propulsion — this propeller is built for durability and reliability on the water.

One of the standout features is the interchangeable Rubex hub kit system, allowing seamless installation on different engines without purchasing a new propeller. This modular design saves costs in the long run and offers flexibility for upgrades or engine swaps. The blade design maximizes water displacement and thrust, ensuring top-tier fuel economy and stability.

Key Features and Benefits of Rubex 3 Propeller

Marine enthusiasts appreciate the Rubex 3 marine propeller for its consistent quality and performance. Here are some reasons it’s highly rated:

Durable Aluminum Build: Resists corrosion and wear, ideal for both saltwater and freshwater use.
Right-Hand Rotation: Matches most standard outboard configurations for plug-and-play compatibility.
Interchangeable Hub System: Reduces vibration, simplifies installation, and protects your drive train.
Balanced Blade Geometry: Enhances speed and control while minimizing cavitation.
OEM Compatibility: Works with Mercury, Yamaha, Evinrude, and Honda outboards (with correct hub kit).

Designed for reliability, the Rubex 3 also serves as a great replacement for OEM parts — combining cost-efficiency with comparable or better performance.

Performance Testing and Real-World Feedback

Boaters who’ve installed the Rubex 3 (10.5 x 11″) Solas RH Propeller report noticeable improvements in engine responsiveness and fuel savings. On smaller outboard boats (25HP–60HP), test runs indicate better hole shots and mid-range cruising with less vibration and noise.

Real-world reviews also emphasize the Rubex 3’s ability to maintain speed in choppy conditions without over-revving the engine. Many users have reported smoother gear shifting and less prop slippage, which is often an issue with poorly matched or worn-out props. This prop is especially popular with aluminum fishing boats, pontoon owners, and lightweight center consoles.

Compatibility and Installation Guidelines

The Rubex 3 Solas RH Propeller is compatible with various engine brands when paired with the proper Rubex hub kit (sold separately). Compatible engines include:

Mercury Outboards (25-70 HP)
Yamaha (20-70 HP)
Honda (35-60 HP)
Tohatsu/Nissan (25-70 HP)

Installation is straightforward. Using the correct Rubex hub kit, simply remove your old propeller, align the new prop, insert the hub, and torque the nut to your manufacturer’s specifications. Always use marine-grade grease and ensure proper cotter pin placement for safety.

Maintenance Tips

To extend the life of your Rubex 3 marine propeller, routine maintenance is essential. Here’s how to keep it in top shape:

Inspect After Every Use: Check for dings, cracks, or fishing line wraps.
Clean with Freshwater: Especially after saltwater exposure to prevent corrosion.
Grease the Shaft: Remove and lubricate your prop shaft every 20-30 running hours.
Balance Testing: Consider a professional balance check every season for maximum efficiency.

Store your boat with the propeller facing down or removed entirely. Prop damage is often caused during dry storage, not operation.

Expert Advice and Pro Recommendations

Marine technicians recommend the Rubex 3 for users looking to balance cost with performance. If you’re not sure what pitch or size fits your engine, refer to your owner’s manual or contact a marine service expert. Undersized props may cause over-revving, while oversized props can stall acceleration and strain your engine.

Detailed FAQ Section

What engines are compatible with the Rubex 3 (10.5 x 11″) Solas RH Propeller?

The Rubex 3 (10.5 x 11″) is designed for right-hand rotation outboards between 25HP to 70HP, including brands like Mercury, Yamaha, Honda, Nissan, and Tohatsu. Compatibility depends on pairing the prop with the correct Rubex hub kit. Always refer to engine manufacturer recommendations or contact a marine expert before purchasing. If unsure, All Boat Supplies provides compatibility assistance — just drop a message in the chat.

How do I install the Rubex 3 propeller properly?

Begin by removing your old propeller, cleaning the shaft, and applying marine grease. Slide the Rubex hub kit into the new propeller, then align it with the engine shaft. Torque the nut according to your engine’s specifications and secure it with a cotter pin. Check for free rotation and test run at low speeds before heading out for full-speed boating.

Is the Rubex 3 propeller good for saltwater use?

Yes, the Rubex 3 is crafted from high-quality aluminum with corrosion-resistant coatings, making it suitable for both freshwater and saltwater applications. However, post-use cleaning with freshwater and occasional re-greasing are highly recommended to maximize lifespan and prevent galvanic corrosion on the prop shaft or hub.

What are the signs that I need to replace my propeller?

Signs include visible damage like cracks, bent blades, or corrosion. Performance issues such as excessive vibration, poor acceleration, over-revving, or reduced fuel efficiency may also indicate your propeller is worn or mismatched. Frequent line entanglement around the shaft and chipped blade tips are other indicators. Regular inspections help detect problems early.

What’s the difference between pitch and diameter in propellers?

Diameter is the width of the circle made by the blade tips during rotation. Pitch refers to the distance the prop would move in one rotation through a soft solid (like a screw through wood). A higher pitch offers better top speed but reduces acceleration. The Rubex 3 (10.5 x 11″) balances diameter and pitch for mid-range boats, offering both good takeoff and cruising speeds.

Conclusion

The Rubex 3 (10.5 x 11″) Solas RH Propeller, 9211-105-11 is a stellar choice for boaters seeking efficiency, durability, and compatibility in a single solution. Designed for precision and backed by one of the most reputable names in marine propulsion, this propeller elevates your boating experience without compromising budget. Whether you’re upgrading from stock or replacing a damaged unit, the Rubex 3 provides the ideal balance of performance and peace of mind.
