Solas RBX-107 Rubex Hub Kit For Select Honda Review

What You Didn’t Know About the Solas RBX-107 Rubex Hub Kit For Select Honda

As an equipment specialist who’s spent over a decade putting gear through its paces in everything from remote labs to workshop floors, I’ve learned to appreciate components that perform reliably and intelligently. The Solas RBX-107 Rubex Hub Kit For Select Honda falls into that category, a seemingly simple part designed to solve a very specific, and often frustrating, problem for Honda outboard motor owners. It’s a hub designed to integrate seamlessly with select Honda propellers, aiming to eliminate common operational annoyances.

My personal journey to this particular hub kit began with a persistent vibration issue on a friend’s boat powered by a Honda BF90. While the engine itself was sound, the propeller engagement was rough, leading to a noticeable shudder, especially during initial acceleration and gear changes. This wasn’t just an auditory nuisance; it felt like it was contributing to undue stress on the drivetrain. Finding a robust solution that didn’t involve an entirely new propeller was the goal.

Upon first inspection, the Rubex hub kit presented itself as a solid, well-engineered piece. The one-piece rubber construction, a significant departure from some plastic-heavy alternatives, immediately inspires confidence. Coupled with anodized aluminum splines, it feels built to withstand the harsh marine environment and the constant torque it’s designed to manage. I briefly considered a generic rubber hub replacement, but the specific design and reputation of the Solas Rubex system for Honda outboards tipped the scales. My initial impression was one of quiet satisfaction, a feeling that a well-thought-out solution had arrived.

Real-World Testing: Putting Solas RBX-107 Rubex Hub Kit For Select Honda to the Test

First Use Experience

My testing scenario was straightforward: installing the Solas RBX-107 Rubex Hub Kit For Select Honda on a prop that was experiencing the aforementioned vibration and chatter issues. The installation took place in my home workshop, a familiar environment where I’ve performed countless similar tasks. The process was remarkably intuitive, largely due to the clear instructions provided with the kit.

The real test came on the water. We took the boat out on a calm lake for initial diagnostics, focusing on throttle response and shifting. From the very first engagement, the difference was palpable. The abrupt jolt and vibration that had been present were significantly reduced, replaced by a much smoother transition.

Even with repeated gear changes from neutral to forward and reverse, the hub kit performed admirably. There was a subtle, yet reassuring, dampening effect when shifting, a marked improvement over the harsh clunking that had been the norm. Exposure to the marine environment—salt spray from a previous outing and humidity in the air—didn’t seem to impact its function; it performed consistently throughout the day’s testing.

Extended Use & Reliability

Over the following weeks, the Rubex hub kit was subjected to more varied conditions. This included slower trolling speeds where engine vibration can be more pronounced, as well as longer runs at cruising and WOT (Wide Open Throttle) speeds. The initial smoothness was maintained, and the prop continued to feel securely seated without any signs of slippage or excessive play.

Durability has been a key focus, and after multiple outings, the Solas RBX-107 Rubex Hub Kit shows no signs of premature wear. The rubber remains pliable, with no cracking or hardening observed, and the aluminum splines show no stripping. This is a welcome contrast to past experiences with cheaper, all-plastic hub assemblies that often degrade under stress.

Maintenance has been virtually non-existent. A simple rinse with fresh water after saltwater use is all that’s required, and given its one-piece construction, there are no complex parts to clean or maintain. Compared to some aftermarket propeller hubs that require specific grease or sealants, the low-maintenance nature of this Rubex kit is a significant advantage. It’s a testament to its robust design that it continues to perform as well as it did on day one, even after extended, real-world use.

Breaking Down the Features of Solas RBX-107 Rubex Hub Kit For Select Honda

Specifications

The Solas RBX-107 Rubex Hub Kit is engineered for specific Honda outboard models, offering a precise fit. It is constructed from a one-piece rubber construction for superior vibration dampening and durability, integrated with anodized aluminum splines to prevent corrosion and ensure a secure connection to the propeller shaft. This hub kit offers 10° of deflection, a crucial feature designed to absorb shock when shifting gears or encountering submerged objects.

This unique deflection capability acts as a built-in shock absorber, protecting both the propeller and the outboard’s drivetrain from the sudden impacts that can occur in boating. The material choice—rubber over plastic—is paramount for longevity, as plastics can become brittle and crack over time, especially in marine environments. The 15-tooth spline count and specific gearcase compatibility (e.g., 4-1/4″ and 4-3/4″ gearcases) are critical specifications that ensure proper mating with compatible Honda engines and propellers.

Performance & Functionality

The primary job of the Solas RBX-107 Rubex Hub Kit is to eliminate propeller hub chatter and vibration, while also preventing slippage. In this regard, it performs exceptionally well. The one-piece rubber construction is highly effective at isolating engine vibration, resulting in a noticeably smoother ride and quieter operation.

Its main strength lies in its dual-action capability: not only does it smooth out operation, but the 10° deflection provides a protective buffer against impacts. This offers peace of mind when navigating shallower waters or areas prone to submerged debris. While it meets expectations for vibration dampening, the impact absorption is a welcome bonus that elevates its functionality beyond basic hub replacement.

Design & Ergonomics

The design philosophy behind the Rubex hub kit is clearly focused on robust simplicity and effectiveness. The one-piece rubber construction signifies a commitment to durability and reduced failure points. The inclusion of anodized aluminum splines further enhances this by providing a strong, corrosion-resistant interface with the propeller shaft.

Ergonomically, once installed, it’s designed to be a passive component, meaning it doesn’t require any direct user interaction. Its effectiveness is felt through the smoother operation of the boat rather than through any physical manipulation. The design ensures a tight fit within the propeller’s hub cavity, preventing the kind of looseness that leads to chatter.

Durability & Maintenance

Solas has clearly prioritized durability with the Solas RBX-107 Rubex Hub Kit. The use of high-quality, marine-grade rubber combined with anodized aluminum suggests a product designed for the long haul. It’s built to withstand the constant torque, shock loads, and corrosive marine environment without degradation.

Maintenance is exceptionally straightforward; it’s designed to be virtually maintenance-free. Regular rinsing with fresh water is recommended to prolong the life of the rubber, but beyond that, no special care is needed. Potential failure points are minimized due to its singular, solid construction. The absence of plastic components that can become brittle over time is a significant factor in its long-term reliability.

Accessories and Customization Options

The Solas RBX-107 Rubex Hub Kit is designed as a self-contained unit, and typically, it includes all the necessary hardware for installation, along with clear instructions. No additional accessories are generally required for its function or installation with compatible propellers and engines. Customization is limited to selecting the correct Rubex hub kit for your specific Honda outboard model and propeller spline count.

The key “accessory” here is the 10° deflection feature, which is an integrated aspect of the design rather than an add-on. This inherent feature is what sets it apart and contributes to its overall protective functionality. Compatibility is key, so ensuring you have the correct model number for your specific Honda engine (e.g., BF60, BF75, BF90, BF115, BF130, BF135-250) and gearcase size is the primary consideration.

Pros and Cons of Solas RBX-107 Rubex Hub Kit For Select Honda
