Key Features of the Rubex S3 15.125 x 28″ Propeller
- Size: 15.125-inch diameter x 28-inch pitch
- Rotation: Right-Hand (RH)
- Material: High-chromium stainless steel for corrosion resistance
- Compatibility: Designed for high-performance outboards and stern drives
- Replaceable Hub System: Compatible with Rubex interchangeable hub kits
This specific sizing allows for maximum torque transfer and helps reduce slippage during acceleration—ideal for high-performance vessels and aggressive boating activities.
Why Choose a Stainless Steel Propeller Like the Rubex S3?
Compared to aluminum propellers, stainless steel options like the Rubex S3 are far more durable and resilient under stress. They don’t flex as much under load, meaning more energy is transferred from the engine to the water. This results in improved top-end speed, better fuel efficiency, and a more responsive throttle.
The Solas Rubex S3 propeller also features a custom blade geometry that enhances acceleration while reducing vibration and noise. It’s built to withstand everything from coastal waters to freshwater lakes, making it a versatile choice for boaters across the spectrum.
How to Install the Rubex S3 Propeller
Installing the Rubex S3 propeller is straightforward thanks to Solas’ innovative interchangeable hub system. Here’s how to get it done:
- Remove the old propeller from your engine’s shaft.
- Insert the Rubex hub kit into the new S3 propeller.
- Slide the assembled propeller onto the prop shaft.
- Secure with the thrust washer and nut.
- Torque to manufacturer specifications and install cotter pin if required.
Always refer to your engine manual and the Rubex installation guide to ensure a precise fit and avoid damage. Use marine-grade grease on the shaft to ease installation and removal in the future.
Performance Benefits in Real-World Conditions
Many marine enthusiasts have tested the Rubex S3 15.125 x 28″ propeller in real-world settings. From heavy loads to high-speed cruising, it consistently delivers:
- Faster Hole Shots: Reduced cavitation means quicker acceleration
- Higher Top Speeds: Ideal for bass boats, ski boats, and performance pontoons
- Better Fuel Economy: Efficient blade geometry reduces engine strain
- Lower Noise: Balanced construction minimizes engine and hull vibrations
This propeller stands out particularly when paired with mid-to-high horsepower engines from Yamaha, Suzuki, Mercury, and Honda.
Maintenance Tips
Proper maintenance of your Rubex S3 propeller can extend its life and keep performance at its peak. Here are a few critical tips:
- Rinse After Use: Always rinse your propeller with fresh water after exposure to saltwater to prevent corrosion.
- Inspect Regularly: Check for signs of pitting, dings, or cracks that can affect performance or indicate hidden damage.
- Remove Seasonally: If storing your boat for winter, remove the propeller to clean, inspect, and grease the shaft.

Detailed FAQ Section
Is the Rubex S3 15.125 x 28″ compatible with all outboards?
No, the Rubex S3 (15.125 x 28″) propeller is not universally compatible with every outboard engine. It is primarily designed for high-performance outboards and stern drives. Always refer to your engine’s pitch and diameter recommendations. Solas provides compatibility charts that match the right propeller model and hub kit with your engine brand—such as Yamaha, Mercury, Evinrude, Suzuki, and Honda. It’s also critical to verify whether your engine uses RH or LH rotation. The Rubex S3 9561-151-28 is a Right-Hand rotating propeller. If you’re unsure, it’s best to consult a marine mechanic or contact AllBoatSupplies.com for support.
How do I know if the 28-inch pitch is right for my boat?
The pitch of a propeller affects your engine’s RPM at full throttle. A 28-inch pitch is considered high and is generally suitable for light, fast boats or vessels with high horsepower engines that can maintain optimal RPMs without overloading. To determine if 28” is right for you, check your engine’s recommended WOT (Wide Open Throttle) RPM range. If your engine is under-revving with a lower pitch prop, moving up to 28” could optimize performance. Conversely, over-revving suggests a lower pitch might be needed. Sea trials, prop calculators, and advice from marine specialists can help in selecting the correct pitch for your vessel and load conditions.
Can I use the Rubex S3 propeller in saltwater?
Yes, the Rubex S3 propeller is designed for both saltwater and freshwater environments. Made from high-chromium stainless steel, this propeller resists corrosion and pitting caused by prolonged saltwater exposure. However, regular maintenance is vital. Rinse the propeller with fresh water after every saltwater use, inspect for marine growth or buildup, and apply anti-seize compound to the shaft threads. Additionally, ensure the hub remains sealed and tight, as salt can accelerate wear on unprotected components. For long-term saltwater durability, this model is among the best propeller options available.
What are signs that my Rubex S3 propeller needs replacement?
Several symptoms indicate your propeller may need replacement:
- Vibration while cruising – Can suggest a bent blade or damaged hub.
- Decreased fuel efficiency – May result from cavitation or improper pitch alignment.
- Visible cracks or nicks – Affect balance and hydrodynamic efficiency.
- Hub slippage – If the engine revs high but the boat moves slowly, the rubber hub insert may be worn.
Routine inspections can catch these issues early. If unsure, a marine shop can test propeller integrity and recommend repair or replacement.
How do I choose the right Rubex hub kit for this propeller?
The Rubex S3 series uses a separate, interchangeable hub kit system. This allows the same propeller to fit a range of engines. To choose the right kit:
- Identify your engine make, model, and year.
- Check the Solas Rubex hub compatibility chart or use their online tool.
- Select the correct hub that matches your engine shaft and spline count.
This modular system reduces cost and waste, since you can reuse the hub across compatible propellers. It’s one of the features that makes Solas a top pick for flexible marine propulsion setups.
