Real-World Testing: Putting Solas RBX-113 Rubex Hub Kit For Honda 35 50 Hp, 1991 & Newer to the Test
First Use Experience
My initial test for this Rubex hub kit was performed on my personal 19-foot aluminum boat, equipped with the aforementioned Honda BF50 outboard. The installation took place in my home garage, a familiar environment for mechanical work. The conditions were typical for a late spring day – moderate temperature and dry.
The real test, however, came on the water. I ran the boat through a variety of scenarios: slow trolling, moderate cruising speeds, and full throttle acceleration. I specifically focused on how the engine engaged and how it handled sudden throttle changes, paying close attention to any hub chatter or vibration.
Ease of installation was surprisingly good; the kit came with clear instructions and all the necessary hardware. It was far more intuitive than I initially anticipated, requiring only basic tools and about twenty minutes of my time. The most notable positive surprise was the immediate reduction in propeller noise once everything was tightened down.
Extended Use & Reliability
After several weeks of regular use, including a few longer excursions and some challenging chop, the performance of this hub kit has been consistently impressive. The engine now engages with a satisfying solid feel, and the irritating propeller vibration that plagued me before is completely gone. It’s made a significant difference in the overall ride quality and my confidence in the propulsion system.
In terms of durability, there are no visible signs of wear or tear on the Rubex hub. The rubber remains supple, and the aluminum splines show no signs of corrosion or damage, even after exposure to saltwater and occasional splashes. This is a testament to its robust construction and the quality of the materials used.
Maintenance has been virtually non-existent. Beyond an initial rinse with fresh water after saltwater use, which is standard practice for any outboard component, this hub kit requires no special attention. It’s a “set it and forget it” kind of component, which is exactly what you want when addressing a functional issue on a boat engine. Compared to the previous OEM hub that eventually failed, this Solas unit feels like a substantial upgrade in terms of longevity and performance retention.
Breaking Down the Features of Solas RBX-113 Rubex Hub Kit For Honda 35 50 Hp, 1991 & Newer
Specifications
The Solas RBX-113 Rubex Hub Kit For Honda 35 50 Hp, 1991 & Newer is meticulously engineered to integrate seamlessly with specific Honda outboard models. It is designed for engines including the BF 35 & BF 45 (1991-94), BF 40, 50, & 50A (1995 & Newer), and BF 60 (2010 & Newer). A key specification is its 13 Tooth Spline count, crucial for proper gear engagement with the matching propeller shaft.
Furthermore, this hub kit is built for a 3-1/4″ Gearcase diameter, ensuring a precise fit within the intended propeller hub cavities. The core of its design lies in its one-piece rubber construction with anodized aluminum splines. This material choice is critical for its functionality; the rubber provides the necessary flex, while the aluminum splines ensure a secure, non-slipping connection to the propeller shaft.
This specific design offers 10 degrees of deflection. This engineered flex is not just a number; it’s a functional aspect that significantly reduces the jarring impact felt when shifting gears or, importantly, when the propeller inadvertently strikes a submerged object. Unlike some lesser designs, all RBX hubs are designed to be reusable even if the propeller itself sustains damage, adding a layer of long-term value.
Performance & Functionality
The primary function of this Rubex hub kit is to eliminate propeller hub chatter and vibration while preventing slippage. In my experience, it excels at this. The moment the engine engaged after installation, the difference was palpable. The boat now accelerates smoothly and powerfully without any of the distracting mechanical noise.
The 10 degrees of deflection is a standout feature that truly benefits the user experience. When shifting from neutral to forward or reverse, the engagement is remarkably smooth, without the typical “clunk” or harsh jolt. More importantly, during a recent outing where I accidentally clipped a submerged log, the hub absorbed the impact beautifully. Instead of a violent shudder or potential prop damage, there was a controlled give, allowing me to regain control quickly and safely.
This hub kit not only meets but exceeds expectations for its intended purpose. The price point of $53.49 feels entirely justified by the significant improvement in operational smoothness, the reduction in potential stress on the drivetrain, and the built-in protection against minor impacts. It’s a small component that delivers a disproportionately large positive impact on the boating experience.
Design & Ergonomics
The design of the Solas RBX-113 Rubex Hub Kit is commendably straightforward, focusing on durability and function. The use of one-piece rubber construction means there are no glued seams or multiple parts that could potentially fail over time. This monolithic design contributes to its robust feel and perceived longevity.
The integration of anodized aluminum splines into the rubber is a smart engineering choice. It ensures that the critical connection points are protected from corrosion and wear, while providing the necessary rigidity for efficient power transfer. The overall construction feels solid, with no flex or play where it shouldn’t be, yet it possesses the engineered give where it matters most.
Ergonomically, the “design” for a hub kit is primarily about its installation and how it interfaces with the propeller and the engine shaft. In this regard, it is excellent. The fit was precise, requiring no excessive force, and the final assembly felt secure and well-seated within the propeller’s hub cavity. The instructions provided were clear and easy to follow, making the installation process straightforward even for someone with moderate mechanical experience.
Durability & Maintenance
Based on my extended use and the materials employed, the durability of this Rubex hub kit appears to be excellent. The one-piece rubber construction is designed to withstand the continuous stress and flexing inherent in propeller operation. Unlike traditional rubber hubs that can become brittle or tear over time, the compound used here feels resilient and resistant to degradation.
The anodized aluminum splines offer crucial protection against corrosion, especially important for a component operating in saltwater environments. This prevents the splines from seizing or becoming damaged, ensuring that the hub can be removed and potentially reused if necessary. I’ve experienced other hub kits where the aluminum corroded and made removal a nightmare, so this attention to detail is a significant advantage.
Maintenance is essentially zero. Once properly installed, the hub kit is protected within the propeller and the gearcase. Regular flushing of the outboard with fresh water after saltwater use is the only “maintenance” required, which is standard practice. There are no delicate mechanisms or lubrication points to worry about, making it a hassle-free component.
Accessories and Customization Options
The Solas RBX-113 Rubex Hub Kit For Honda 35 50 Hp, 1991 & Newer comes as a complete package, including all necessary hardware for installation. This typically includes a washer and a nut designed to work with the kit. The manufacturer also provides easy-to-use instructions, which are invaluable for a smooth installation process.
There are no significant customization options for the hub kit itself, as its design is highly specific to the intended propeller and engine shaft. However, the reusable nature of the hub if the propeller is damaged could be considered a form of long-term value customization. This means that if you happen to damage a propeller, you don’t necessarily have to replace the hub along with it, saving on future costs. The kit is designed for a specific spline count and gearcase size, so its “customization” lies in its precise fitment for compatible Honda outboards.
