Overview / What Is Rubex Hydro (13.125 x 22″) Solas RH Propeller?
The Rubex Hydro 9481-131-22 is a premium stainless steel propeller that offers precision engineering for high-performance marine engines. Designed for outboard motors requiring RH rotation, this propeller features an aggressive blade profile, optimal cupping, and a robust Rubex interchangeable hub system. Its hydrodynamic design improves hole shot, cornering, and fuel economy.
The 22-inch pitch is well-suited for boats aiming for higher speeds without compromising throttle response. The stainless steel blades maintain their geometry even at high RPMs, which is vital for consistency and reliability on the water. This model is particularly effective for mid-to-large outboard engines in the 115–200 HP range.
Blade Geometry and Hydrodynamic Benefits
One of the standout features of the Rubex Hydro 13.125 x 22″ Solas RH Propeller is its advanced blade geometry. The unique rake and cup design improves water grab, decreases cavitation, and optimizes fuel burn. This contributes to a quieter ride and reduced vibration at cruising speed.
Hydrodynamic efficiency is critical when operating in varying marine conditions, and this propeller’s aggressive rake enhances lift at the stern, allowing boats to plane more efficiently. This makes it a favorite among offshore anglers and performance-minded boaters alike.
How to Install Rubex Hydro Propeller 9481-131-22
Installing the Rubex Hydro propeller is straightforward, especially with the Rubex interchangeable hub system. Here’s how to install it:
- Turn off the engine and place it in neutral. Remove the old propeller using a prop wrench.
- Apply marine grease to the propeller shaft to prevent corrosion and ease installation.
- Press-fit the Rubex hub kit into the new propeller barrel using a rubber mallet if necessary.
- Slide the prop onto the shaft, aligning it with the thrust washer.
- Install the prop nut and secure it with a cotter pin. Torque to specifications recommended in your outboard’s manual.
Regularly inspect the prop nut and hub kit after the first few runs to ensure everything remains secure.
Performance Advantages of 13.125 x 22″ Propeller
The Rubex Hydro 9481-131-22 model is engineered for efficiency and top-end performance. It excels in conditions where sustained speed, tight turning radius, and high-speed cruising are necessary. Compared to standard aluminum propellers, it provides:
- Better acceleration with reduced ventilation
- Higher top speed for similar engine RPMs
- Reduced drag due to precise blade angles
- Increased torque transfer for heavier loads
- Longer lifespan in marine environments
Its stainless steel build not only delivers power but maintains performance under stress, making it a more reliable option for challenging waters.
Maintenance Tips
To keep your Rubex Hydro 13.125 x 22″ Solas RH Propeller in optimal condition, proper maintenance is essential. Follow these maintenance tips for best results:
- Clean the blades after every trip, especially in saltwater. Use mild soap and water, avoiding acidic or abrasive cleaners.

Detailed FAQ Section
How do I know if the Rubex Hydro 13.125 x 22” propeller fits my boat?
Fitment depends on your engine brand, horsepower, and shaft specifications. The Rubex Hydro 13.125 x 22″ Solas RH Propeller is compatible with many outboards from Mercury, Yamaha, Honda, Suzuki, and Tohatsu when paired with the correct Rubex hub kit. It’s best suited for engines between 115 HP and 200 HP. Always check your engine manual or consult a marine technician for compatibility. Using a propeller with incorrect pitch or diameter can negatively affect your boat’s performance and engine health.
What is the difference between stainless steel and aluminum propellers?
Stainless steel propellers like the Rubex Hydro are more durable and retain their shape under stress, offering consistent pitch and better long-term performance. They resist corrosion better and offer superior handling, especially at high speeds or under heavy loads. Aluminum props, while more affordable, are prone to bending and cavitation. If you’re seeking longevity and high output, stainless steel is the better choice—especially in saltwater environments.
How do I maintain my Rubex Hydro stainless prop for longevity?
Maintenance includes regular cleaning with freshwater, greasing the shaft every 25–50 hours, and inspecting the hub kit for wear. Store the prop in a dry location during the off-season. Avoid hitting sandbars or rocks, as stainless props are tough but not immune to impact damage. Marine professionals recommend propeller inspection before every voyage to ensure safety and maximum performance.
Can I expect improved fuel economy with this propeller?
Yes, many users report up to 10–15% improved fuel economy when switching to the Rubex Hydro 13.125 x 22″ Solas RH Propeller from standard aluminum props. The advanced blade geometry reduces slippage and drag, allowing your engine to work more efficiently at cruising speed. Over time, this can lead to noticeable savings in fuel costs, especially for long-distance or frequent trips.
What should I do if I experience vibration after installing the propeller?
Vibration is often caused by improper installation, incorrect hub alignment, or unbalanced blades. First, ensure the prop is correctly torqued and that the hub kit is fully seated. Inspect the blades for damage or imbalance. If the issue persists, consult a marine technician to check shaft alignment and balance. Addressing vibrations early can prevent damage to the lower unit and engine seals.
Conclusion
The Rubex Hydro (13.125 x 22″) Solas RH Propeller, 9481-131-22 is a top-tier solution for marine enthusiasts who prioritize performance, reliability, and longevity. Its stainless steel construction, precision blade design, and compatibility with multiple engines make it one of the best stainless propeller options on the market today. Whether you’re cruising, fishing, or tackling waves offshore, this prop will enhance your boating experience in every way.
