Uncovering the Solas 9501-155-13DC Rubex 3 Plus Aluminum 3 Blade Double Cupped Prop Rh 15.5″ Dia. x 13″ Pitch: Real Review
For any boater who has ever wrestled with a sluggish hole shot or felt the sting of prop vibration, finding the right propeller is paramount. This is where the Solas 9501-155-13DC Rubex 3 Plus Aluminum 3 Blade Double Cupped Prop Rh 15.5″ Dia. x 13″ Pitch enters the conversation, a piece of marine hardware promising a blend of performance and durability. My own journey to this specific propeller began with a boat that felt… hesitant. The previous prop, a generic aluminum unit, simply wasn’t delivering the acceleration I needed for watersports, and the constant low-frequency rumble was becoming tiresome on longer runs.
Upon receiving the Solas prop, my initial impression was one of robust construction. The aluminum felt solid, and the finish was smooth, hinting at a well-executed manufacturing process. I had considered other brands, notably Mercury and Yamaha, but the unique Rubex 3 Plus interchangeable hub system on this Solas model particularly caught my eye, offering a potential solution to the vibration issue. My immediate reaction was a sense of cautious optimism – could this prop finally unlock the performance my outboard was capable of?
Real-World Testing: Putting Solas 9501-155-13DC Rubex 3 Plus Aluminum 3 Blade Double Cupped Prop Rh 15.5″ Dia. x 13″ Pitch to the Test
First Use Experience
My testing grounds were the familiar waters of a local lake, typically a mix of calm conditions for initial runs and some chop stirred up by other boaters. I mounted the Solas 9501-155-13DC onto my 150hp outboard, which is rated for this size and pitch, replacing an older, worn aluminum prop. The installation itself was straightforward, with the included hub system fitting snugly.
The first surge out of the hole was noticeably different. The boat lifted onto plane much faster and with significantly less struggle than before. The double-cupped design seemed to grip the water effectively, reducing any cavitation I might have experienced previously. Throughout the day, I tested various speeds, from slow trolling to full throttle, and the propeller maintained a consistent, smooth performance.
The Rubex hub system immediately made its presence felt. The usual vibration that accompanied my old prop, especially at cruising speeds, was dramatically reduced. It wasn’t entirely eliminated, as aluminum props will always have some characteristic hum, but it was a night-and-day difference. There were no unexpected quirks or issues; the integration of this prop felt seamless.
Extended Use & Reliability
Over the next few months, this Solas propeller became my go-to on the water. I subjected it to a variety of conditions, from early morning glass to afternoon swells, and even a few accidental brushes with submerged debris. The prop showed remarkable resilience. Despite a few minor scuffs from glancing submerged logs, the blades held their shape and showed no signs of damage that would affect performance.
Maintenance has been minimal. A quick rinse with freshwater after each outing and a periodic check for any debris lodged in the blades are all that’s required. Compared to my previous prop, which had started to show signs of pitting and minor nicks after similar use, this Solas unit felt significantly more robust. It consistently delivered strong acceleration and a comfortable top-end speed, holding its own against both budget aluminum props and more expensive stainless steel alternatives I’ve used in the past.
Breaking Down the Features of Solas 9501-155-13DC Rubex 3 Plus Aluminum 3 Blade Double Cupped Prop Rh 15.5″ Dia. x 13″ Pitch
Specifications
The Solas 9501-155-13DC Rubex 3 Plus Aluminum 3 Blade Double Cupped Prop Rh 15.5″ Dia. x 13″ Pitch is an aluminum, three-blade propeller designed for right-hand rotation. Its core specifications include a 15.5-inch diameter and a 13-inch pitch, which are crucial for matching to an outboard’s power curve and the boat’s hull. The double-cupped blade design is engineered to provide enhanced grip and reduce ventilation during acceleration and aggressive maneuvering.
The real standout specification is the exclusive squeeze cast process used for its construction, which contributes to stronger blades with better performance characteristics. This process, along with the interchangeable Rubex rubber hub system, sets it apart. The rubber hub is designed to absorb shock, reduce vibration, and prevent damage to the propshaft if an impact occurs. This differs from many competitor’s rigid hub systems that can transmit more shock.
Performance & Functionality
In terms of its primary job, this Solas propeller performs exceptionally well for its class. The outstanding acceleration it provides is immediately noticeable, allowing for quicker planing and better performance when pulling skiers or tubers. The top speed also sees a slight improvement over my old prop, likely due to the optimized blade design and reduced drag from vibrations.
Its main strength lies in the balance it strikes between performance and vibration dampening. The double-cupped blades provide excellent water “bite,” leading to responsive handling and minimal slippage. However, as an aluminum propeller, it’s inherently less durable than stainless steel options when encountering significant impacts. For its intended use and price point, it offers a very strong performance envelope.
Design & Ergonomics
The design of this Solas propeller is functional and purpose-built. The squeeze cast aluminum gives it a solid feel, and the overall finish is clean and professional. The blades themselves are well-shaped, with the double cupping being a key ergonomic feature for water engagement.
The Rubex 3 Plus interchangeable hub system is a significant ergonomic win. It ensures a smooth installation and, more importantly, a noticeably quieter and smoother ride. The rubber material of the hub is designed to flex slightly, offering a forgiving response when shifting gears and providing a buffer against sudden shocks.
Durability & Maintenance
From my experience, the durability of this propeller is good for an aluminum unit, especially thanks to the squeeze cast process which theoretically strengthens the material. It holds its shape and sharpness well under normal operating conditions. While it’s not indestructible and impacts can cause damage, it appears more resilient than many standard cast aluminum propellers.
Maintenance is refreshingly simple. A regular cleaning and inspection are all that’s needed. The interchangeable hub system is also designed for easy replacement if it ever wears out or is damaged, which is a significant plus for long-term ownership. There are no complex lubrication points or intricate parts that require special attention.
Accessories and Customization Options
The primary “accessory” that comes integrated with the Solas 9501-155-13DC Rubex 3 Plus Aluminum 3 Blade Double Cupped Prop Rh 15.5″ Dia. x 13″ Pitch is its Rubex 3 Plus interchangeable hub system. This system is designed to be a complete package, meaning specific hub kits are required for installation on different engine brands or models, but the propeller itself comes ready to accept the appropriate hub.
Beyond the hub, there are no other significant accessories included or customization options typically associated with propellers themselves. The customization here lies in selecting the correct pitch and diameter for your specific boat and engine combination, which this model does with its 15.5″ Diameter x 13″ Pitch configuration.
