Solas 9411-139-17 Rubex 3 Aluminum 3 Blade Prop Rh 13.875″ Dia. x 17″ Pitch Review

Let’s Dive into Solas 9411-139-17 Rubex 3 Aluminum 3 Blade Prop Rh 13.875″ Dia. x 17″ Pitch

The Solas 9411-139-17 Rubex 3 Aluminum 3 Blade Prop Rh 13.875″ Dia. x 17″ Pitch is more than just a replacement propeller; it’s a potential performance upgrade for a wide range of boats. Crafted by Solas, a well-respected name in marine propulsion, this prop promises better acceleration and top speed through its enhanced blade design and RUBEX interchangeable hub system. I’ve spent years optimizing boat performance, and I’m eager to see if this prop lives up to the hype.

My old prop was showing its age, suffering from dings and reduced efficiency after a close encounter with a submerged log. I was searching for a durable, performance-oriented aluminum prop that could restore my boat’s responsiveness without breaking the bank. The Solas Rubex 3, with its claimed improvements and reasonable price, seemed like a strong contender compared to other options on the market.

Unboxing the prop, my first impression was positive; the aluminum casting looked clean and precise, and the blades felt robust. The finish was smooth and the overall weight felt balanced, indicating a quality manufacturing process. Comparing it to my previous prop, a standard OEM aluminum model, the Rubex 3’s blades had a more aggressive rake and appeared slightly thicker, hinting at improved hydrodynamic efficiency.

I ultimately chose the Solas over competing brands like Michigan Wheel and Turning Point due to its patented RUBEX hub system, promising smoother shifting and reduced prop shaft shock. Many props offer similar pitch and diameter options, but the integrated hub is what ultimately made my decision. My initial excitement was high – if the Solas performed as advertised, it would be a significant upgrade at a fraction of the cost of a stainless-steel prop.

Real-World Testing: Putting Solas 9411-139-17 Rubex 3 Aluminum 3 Blade Prop Rh 13.875″ Dia. x 17″ Pitch to the Test

First Use Experience

My initial testing ground was the local reservoir, a mix of open water and narrow channels perfect for evaluating both top-end speed and low-speed maneuverability. The water was choppy due to a moderate breeze, providing a realistic test of the prop’s ability to maintain grip. Installation was straightforward using the included hardware from the RUBEX hub kit – a welcome change from wrestling with corroded components on my old prop.

The immediate difference was noticeable during acceleration; the boat planed noticeably quicker, with less bow rise. I observed better performance in choppy waters, and the engine seemed to run smoother, especially at mid-range RPMs. I will attribute that to the RUBEX hub system absorbing vibrations.

There were no major issues during the initial run, although I noticed a slight increase in fuel consumption at top speed, likely due to the increased bite of the prop. After the first outing, I was highly impressed with the improved performance and the smooth operation of the RUBEX hub system.

Extended Use & Reliability

After several weeks of regular use – including fishing trips and recreational boating – the Solas prop has held up remarkably well. There are no signs of undue wear, and the aluminum blades have resisted minor impacts with submerged debris without bending or chipping. Regular cleaning with soap and water is all that’s needed to keep the prop looking like new.

The prop maintains its initial performance characteristics, providing consistent acceleration and top speed. It is comparable to a more expensive stainless-steel prop in terms of performance, without the risk of damaging the lower unit if it strikes an object. Compared to my old OEM prop, the Solas Rubex 3 offers a significant improvement in overall boat handling and responsiveness, making it a worthwhile upgrade.

Breaking Down the Features of Solas 9411-139-17 Rubex 3 Aluminum 3 Blade Prop Rh 13.875″ Dia. x 17″ Pitch

Specifications

• Diameter: 13.875 inches – This measurement determines the overall size of the propeller, influencing thrust and maneuverability. A larger diameter, like this, typically provides more thrust, ideal for heavier boats or those needing enhanced low-end power.
• Pitch: 17 inches – Pitch refers to the theoretical distance a propeller travels in one rotation. A 17-inch pitch suggests a balance between acceleration and top speed, making it suitable for a variety of boating applications.
• Rotation: Right Hand (RH) – Right-hand rotation means the propeller turns clockwise when viewed from behind the boat. This is a standard rotation for single-engine setups and must match the engine’s gear case specifications.
• Material: Aluminum – Aluminum provides a good balance of strength, corrosion resistance, and affordability. It’s suitable for general boating use, but more susceptible to damage than stainless steel.
• Blade Design: 3-Blade – A 3-blade design offers a compromise between efficiency, speed, and smoothness. It provides good all-around performance for most boat types, whereas 4-blade props provide increased thrust, and 2-blade props may improve top speed.
• Hub System: RUBEX Interchangeable Hub – This system is designed to reduce vibration and prevent prop spin-out upon impact. The rubber construction deflects upon impact and reduces damage to the lower unit.

These specifications directly impact the performance of the boat. The RUBEX hub system is a standout feature that provides a smoother and more protected ride.

Performance & Functionality

The Solas 9411-139-17 Rubex 3 excels in delivering improved acceleration and a noticeable increase in top-end speed. The RUBEX hub system provides smoother shifting and reduces the jolting often associated with older, less sophisticated prop designs.

The prop demonstrates excellent grip in various water conditions, maintaining consistent performance even in choppy waters. A potential weakness is that aluminum is more susceptible to damage than stainless steel, requiring careful navigation in areas with submerged obstacles. Overall, it meets and even exceeds expectations for an aluminum prop in its price range.

Design & Ergonomics

The Solas prop boasts a clean and efficient design, with hydrodynamically optimized blades for maximum thrust and reduced drag. The casting quality is high, resulting in a smooth finish and a balanced weight distribution. The included RUBEX hub kit simplifies installation and provides a secure and vibration-free connection to the prop shaft.

The prop is very user-friendly and requires no special tools or expertise for installation. The RUBEX hub system simplifies the replacement process.

Durability & Maintenance

While aluminum is inherently less durable than stainless steel, the Solas Rubex 3 appears to be well-constructed and resistant to minor impacts. With proper care and avoidance of submerged obstacles, this prop should provide several seasons of reliable performance.

Maintenance is straightforward: simply rinse with fresh water after each use to remove salt and debris, and periodically inspect for damage. The RUBEX hub is designed to be replaceable, extending the life of the prop in case of a significant impact.

Accessories and Customization Options

The Solas 9411-139-17 Rubex 3 comes with the necessary hardware for installation, thanks to the RUBEX hub kit. While there are no direct customization options for this specific prop, the RUBEX hub system allows for easy swapping of different Solas propellers with compatible hubs, offering flexibility in fine-tuning boat performance. The prop is also compatible with standard prop wrenches and installation tools, making it easy to service and maintain.
