Overview / What Is Rubex HR3 (14.25 x 22″) Solas LH Propeller
The Rubex HR3 9552-143-22 is a high-performance, left-hand (LH) rotation stainless steel propeller designed for outboard engines. With dimensions of 14.25 inches in diameter and a 22-inch pitch, it’s engineered to provide the perfect balance of thrust, speed, and fuel economy for high-torque marine engines. What sets the HR3 apart is its aggressive rake and cupping for enhanced bow lift and grip, especially at high speeds or during sharp turns.
This propeller integrates with the Rubex interchangeable hub kit system, offering users flexibility across multiple engine brands. It’s part of the trusted Solas product family, a global leader in marine propulsion technology, known for precision casting and rigorous quality control.
Key Benefits of Rubex HR3 Propeller
The Rubex HR3 offers a range of marine-grade advantages for both recreational and commercial boating:
- Superior Stainless Steel Design: Resists corrosion, impact, and cavitation damage.
- Left-Hand Rotation: Ideal for twin-engine applications to balance torque and improve handling.
- Interchangeable Hub System: Compatible with Solas Rubex hub kits — no need for re-hubbing with every prop change.
- High Rake Design: Enhances lift and performance under load, ideal for heavier vessels.
- Efficient Fuel Use: Optimized blade geometry results in less drag and better economy.
These design features combine to offer unmatched acceleration, top-end speed, and steady handling, even in choppy conditions.
How to Install Rubex HR3 (14.25 x 22″) Solas LH Propeller
Installing the Rubex HR3 propeller is straightforward with the Solas interchangeable hub system. Here’s how to do it:
- Ensure the engine is off and safely supported out of the water.
- Remove the cotter pin, prop nut, and existing propeller from the shaft.
- Clean the propeller shaft of any debris, rust, or old grease.
- Insert the correct Rubex hub kit into the Rubex HR3 propeller housing.
- Slide the new propeller with hub onto the shaft and secure with the prop nut and cotter pin.
Use marine-grade grease on the shaft to prevent corrosion and ease future removals. Always torque the prop nut to the engine manufacturer’s specifications.
Maintenance Tips
Maintaining your Rubex HR3 (14.25 x 22″) Solas LH Propeller ensures optimal performance and longevity. Follow these best practices:
- Inspect After Every Use: Check for dents, bends, or debris lodged in the blades.
- Lubricate the Shaft: Apply marine-grade grease to prevent rust and freezing.
- Flush Saltwater Residue: Rinse thoroughly with fresh water after saltwater use.
- Store Dry and Elevated: Keep the propeller in a dry location to avoid oxidation or galvanic corrosion.
Regular maintenance prevents vibration, cavitation damage, and loss of performance — especially important in high-speed or commercial boating scenarios.
Understanding Left-Hand Propellers in Twin Engine Boats
A left-hand (LH) propeller like the Rubex HR3 is specifically designed to rotate counter-clockwise, making it an essential component in twin-engine setups. When paired with a right-hand (RH) counterpart, LH props help balance torque forces and improve steering responsiveness.
Using both rotation types minimizes “prop walk,” enhances boat tracking in a straight line, and provides better reverse control. This is why the Rubex HR3 LH model is frequently recommended for port-side engines in twin-outboard systems.
Expert Advice and Pro Recommendations
Marine professionals often recommend the Rubex HR3 9552-143-22 for:
- Mid to high horsepower engines (150–300 HP range)
- Boats used for water sports, fishing, or offshore runs
- Owners looking for a blend of speed and fuel efficiency

Rubex HR3 Troubleshooting Tips
If you’re facing unusual vibrations, slipping acceleration, or reduced speed with the Rubex HR3, consider these common causes:
- Worn or Incorrect Hub: Replace or verify correct Rubex hub kit compatibility.
- Bent Blade: Inspect each blade for deformation; even a slight bend can cause imbalance.
- Debris Obstruction: Remove any rope, weeds, or fishing line tangled in the prop shaft.
Routine inspection and proper alignment during installation help prevent these issues and extend the life of your marine propeller.
Rubex HR3 Performance vs Other Solas Propellers
The Rubex HR3 offers distinct advantages when compared to other Solas propeller models like the Rubex NS3 or Amita 3:
- HR3 vs NS3: HR3 is stainless steel (better durability); NS3 is aluminum (lighter and cheaper).
- HR3 vs Amita 3: HR3 is optimized for speed and load-bearing; Amita 3 is a basic 3-blade recreational option.
This makes the HR3 a premium upgrade for serious boaters who want durability and optimal hydrodynamic performance.
Detailed FAQ Section
What engines are compatible with the Rubex HR3 (14.25 x 22″)?
The Rubex HR3 (14.25 x 22″) Solas LH Propeller is compatible with a wide range of mid-to-high horsepower outboard engines from brands like Yamaha, Honda, Mercury, Evinrude, and Suzuki. The key factor is ensuring the correct Rubex interchangeable hub kit is used. The propeller itself is designed for engines typically ranging between 150 HP to 300 HP. Always consult the Solas compatibility chart or your engine’s owner manual for proper fit.
How do I know if I need a left-hand propeller?
Left-hand (LH) propellers are mainly used in dual-engine setups to counteract the torque of a right-hand (RH) propeller. If your boat has a twin engine, the port side (left) usually takes the LH rotation. However, if you’re using a single-engine setup, your existing engine and transmission system typically determine the rotation direction. Refer to your boat’s documentation or consult a marine mechanic to determine what rotation you need before purchase.
What is the benefit of stainless steel over aluminum in propellers?
Stainless steel propellers like the Rubex HR3 are stronger, more durable, and offer better performance than aluminum props. While aluminum is lighter and less expensive, stainless steel maintains its shape under stress, reducing flex during high-speed operation. This results in superior acceleration, better fuel economy, and longer lifespan — making stainless steel ideal for performance-driven boaters.
How can I extend the life of my Rubex HR3 propeller?
To maximize the lifespan of your Rubex HR3, follow proper care procedures: clean after each use, especially in saltwater; inspect regularly for nicks or bends; lubricate the shaft before each install; and avoid grounding or striking submerged objects. Also, use the correct hub system to reduce stress on the shaft. Winterizing your boat also includes removing the prop and storing it in a dry place.
What does the 14.25 x 22″ specification mean?
The number 14.25″ refers to the diameter of the propeller, while 22″ is the pitch. Diameter affects thrust and stability, whereas pitch determines how far the boat moves forward per propeller rotation. A 22” pitch is considered high, allowing for greater top-end speed. However, boats requiring quick acceleration or heavy load handling may benefit from lower pitch options. This prop is optimized for boats with enough horsepower to turn a higher pitch efficiently.
Conclusion
The Rubex HR3 (14.25 x 22″) Solas LH Propeller, 9552-143-22 stands out as a premium choice for performance boaters. Whether you’re seeking top speed, better handling, or longer lifespan, this propeller delivers unmatched marine reliability. Its stainless-steel build, left-hand rotation, and compatibility with the Solas Rubex system make it a must-have upgrade for discerning boaters. Experience smoother rides, better efficiency, and more responsive controls — all with one powerful upgrade.
