Installing this propeller is a breeze when using the Rubex hub kit system. Whether you’re replacing an old aluminum prop or upgrading from another stainless steel model, installation can be completed in less than 30 minutes with basic tools.
Follow these steps:
- Remove the existing propeller and clean the shaft thoroughly.
- Insert the Rubex hub into the new propeller (if not already pre-assembled).
- Slide the new prop onto the shaft, ensuring proper spline alignment.
- Secure with the thrust washer, nut, and cotter pin (as applicable).
- Tighten to manufacturer torque specs and test rotation for smoothness.
Note: Always refer to your engine manual for torque guidelines and safety instructions.
Maintenance Tips
Proper maintenance ensures that your Rubex S3 15.125 x 24 Solas RH Propeller for marine continues to perform efficiently and lasts for years to come. Here are expert tips to keep your propeller in peak condition:
- Rinse after each use: Always rinse your prop with fresh water after operating in saltwater to remove corrosive residues.
- Inspect regularly: Check for nicks, cracks, and debris entanglement that could affect performance.
- Remove seasonally: Take off the propeller at least once per season to inspect the hub and lubricate the prop shaft.
- Store properly: If storing long-term, clean and dry the prop thoroughly, then apply anti-corrosion spray before storage.
Routine maintenance doesn’t just extend the life of your propeller — it also ensures smoother, safer rides on every trip.
Understanding Pitch and Diameter: Why 15.125 x 24″ Matters
In propeller terminology, diameter refers to the circle made by the blade tips as the prop rotates, while pitch is how far the propeller would move in one rotation through a soft solid like butter. The Rubex S3’s 15.125″ diameter combined with a 24″ pitch offers a balance between torque and top-end speed.
This configuration is ideal for boaters seeking faster top speeds with less engine strain. If your boat is already planing easily but you need more RPM efficiency or fuel savings at cruising speeds, the Rubex S3 15.125 x 24″ is a fantastic choice.
Troubleshooting Common Propeller Issues
Even the most reliable propellers can run into issues if not installed or maintained properly. Here are a few common problems and their solutions:
- Vibration at High Speeds: Check for bent blades or a loose hub system. Replace if damaged.
- Loss of Speed: This could be due to excessive wear, fouling, or wrong pitch size. Consider upgrading or downsizing pitch based on your load and RPM.
- Cavitation: Inspect for blade nicks or improper engine height. Use a cupped prop like the Rubex S3 to minimize cavitation.
If issues persist, consult with a marine mechanic to perform a full diagnostic on your engine and prop system.

Detailed FAQ Section
Can the Rubex S3 (15.125 x 24″) be used in saltwater?
Absolutely. The Rubex S3 9561-151-24 propeller is crafted from high-grade stainless steel, which offers excellent resistance to saltwater corrosion. For best results, rinse the propeller with freshwater after each saltwater outing to extend its lifespan and retain its polished finish. Periodic inspections and marine-grade protective sprays can also further enhance its durability in harsh marine environments.
Which engines are compatible with the Rubex S3 (15.125 x 24″) Solas RH Propeller?
This propeller is designed for use with various outboard engine brands like Yamaha, Mercury, Honda, Suzuki, and Evinrude, provided they use the Solas Rubex interchangeable hub system. The propeller supports mid-to-high horsepower engines and is ideal for boats requiring high-performance acceleration and control. Always refer to your engine’s manual or consult with a marine technician to confirm fitment before purchase.
How to know if the 24″ pitch is right for my boat?
Pitch selection depends on your boat’s weight, engine RPM range, and your typical boating activities. A 24″ pitch propeller like this is ideal for lighter boats or those targeting top-end speed. If you find your engine revving too high at full throttle, moving up in pitch (e.g., from 22″ to 24″) can reduce RPM and improve fuel economy. Conversely, heavier boats may benefit from lower pitch props for better acceleration. Consult with a propeller specialist or use a GPS and tachometer to find your ideal RPM-to-pitch ratio.
What makes the Rubex hub system unique?
The Rubex hub system is an interchangeable hub kit that separates the hub and the propeller body. This allows boaters to reuse the same hub across multiple Solas propellers, making swaps more cost-effective and environmentally friendly. It also provides cushioning against shock loads, improving longevity and reducing gearcase damage in case of underwater strikes. The Rubex hub ensures smoother operation and protects the engine drive system from prop strikes.
What is the expected lifespan of the Rubex S3 stainless propeller?
With proper care and routine maintenance, the Rubex S3 stainless steel propeller can last over 5–10 years. Unlike aluminum propellers, which may bend or corrode quickly in harsh environments, the stainless steel construction retains its blade shape and integrity over many seasons. Regular inspection for dings, lubrication of the shaft, and correct torque during installation are essential practices to maximize longevity.
Conclusion
When performance, reliability, and efficiency matter most, the Rubex S3 (15.125 x 24″) Solas RH Propeller stands above the rest. Ideal for serious boaters and professionals alike, this stainless steel prop provides a perfect balance of speed, strength, and smoothness. With compatibility across leading engine brands and a hub system that simplifies installation and protects your drivetrain, the Rubex S3 is an investment in better boating.
Choose the 9561-151-24 model for peak propulsion and explore water the way it was meant to be — fast, efficient, and worry-free.
