Let’s Dive into Solas 9513-140-21 Rubex 4 Aluminum 4 Blade Prop Rh 14″ Dia. x 21in Pitch
The Solas 9513-140-21 Rubex 4 Aluminum 4 Blade Prop Rh 14″ Dia. x 21in Pitch is a replacement propeller designed to offer improved performance and durability compared to standard three-blade aluminum props. Solas is a well-known manufacturer in the marine industry, and their Rubex series is designed to offer a balance of performance and affordability. The four-blade design, 14-inch diameter, and 21-inch pitch are intended to provide enhanced acceleration, mid-range performance, and stern lift, making it a potential upgrade for boaters seeking better handling and overall efficiency.
My own boat, a 20-foot center console powered by a 140 HP Suzuki outboard, was experiencing sluggish acceleration and a tendency to plow at lower speeds. I needed a prop that would help me get on plane faster and improve my fuel economy, especially when loaded with gear and passengers for fishing trips.
The Solas prop arrived well-packaged. Initial impressions were positive, noting the solid construction and clean finish of the aluminum. Compared to the old three-blade prop it replaced, the Solas Rubex 4 felt significantly more robust and the blades had a more aggressive cupping design.
I considered a stainless steel prop, but the cost was significantly higher. I also looked at another Solas three-blade prop with a slightly different pitch, but the four-blade design of the Solas 9513-140-21 Rubex 4 Aluminum 4 Blade Prop Rh 14″ Dia. x 21in Pitch seemed like the better option for addressing my specific performance concerns. I was cautiously optimistic, hoping this prop would deliver the improved performance I was seeking without breaking the bank.
Real-World Testing: Putting Solas 9513-140-21 Rubex 4 Aluminum 4 Blade Prop Rh 14″ Dia. x 21in Pitch to the Test
First Use Experience
I tested the Solas 9513-140-21 Rubex 4 Aluminum 4 Blade Prop Rh 14″ Dia. x 21in Pitch on a local bay known for its choppy conditions and varying tidal currents. The initial run was with a light load, just myself and minimal gear. The difference was immediately noticeable.
The boat planed much quicker than before, requiring less throttle input. Even in a moderate chop, the prop held its bite well, maintaining a stable and predictable ride. I was impressed with the improvement in low-end torque and the ability to maintain plane at a lower speed.
Extended Use & Reliability
After several months of regular use, the Solas Rubex 4 has proven to be a reliable and worthwhile upgrade. I have used the boat in a variety of conditions, including calm lakes, rough bays, and even a few nearshore trips. The prop consistently delivers improved performance compared to the original three-blade.
There are no significant signs of wear and tear, despite occasional encounters with submerged debris. The aluminum shows no signs of excessive corrosion, and the rubber hub system seems to be holding up well. Cleaning is straightforward; a simple rinse with freshwater after each use keeps it looking good. This prop has definitely outperformed my expectations, offering a noticeable improvement in performance and handling.
