Real-World Testing: Putting Solas RBX-106 Rubex Hub Kit For Select Evinrude/Johnson/Brp/Omc/Cobra Sterndrives to the Test

First Use Experience

My testing grounds for this hub kit were immediately clear: the choppy waters of a local lake during a busy weekend, followed by more controlled testing at idle and during moderate accelerations. I installed the kit on a familiar 21-foot Bayliner with a 130 HP Evinrude sterndrive, a combination that has seen its fair share of wakes and dockings. The installation process itself was straightforward, aligning perfectly with the propeller hub cavity as advertised.

Upon hitting the water, the difference was almost immediate. The incessant thrumming that had become a constant companion was significantly reduced, almost to the point of disappearing. During gear shifts, there was a notable absence of the jarring clunk that I had grown accustomed to. I purposefully ran over a few smaller, submerged debris items (safely, of course) and found that the 10 degrees of deflection the kit offers absorbed some of the shock, preventing the harsh impact that previously would have reverberated through the boat. It felt considerably smoother, almost as if the propeller was now better integrated with the lower unit.

Extended Use & Reliability

After several months of consistent use, spanning multiple fishing trips and recreational outings, the Solas RBX-106 Rubex Hub Kit has proven its mettle. The initial improvement in vibration dampening has remained constant; there’s no discernible degradation in its performance. I’ve found that the one-piece rubber construction shows no signs of cracking or hardening, which is a common failure point in lesser designs.

The anodized aluminum splines are still clean and free from corrosion, indicating a quality finish that holds up to saltwater spray and immersion. Maintenance has been practically non-existent. A quick rinse with fresh water after saltwater excursions is all that’s required, and it hasn’t shown any signs of stiffness or reduced deflection. Compared to previous hub replacements I’ve performed on older sterndrives, this Solas unit feels like a significant step up in terms of longevity and consistent performance. It’s a set-it-and-forget-it kind of part, which is exactly what you want when you’re out on the water.

Breaking Down the Features of Solas RBX-106 Rubex Hub Kit For Select Evinrude/Johnson/Brp/Omc/Cobra Sterndrives

Specifications

The Solas RBX-106 Rubex Hub Kit For Select Evinrude/Johnson/Brp/Omc/Cobra Sterndrives is specifically designed for select Evinrude, Johnson, BRP, OMC, and Cobra sterndrives. It is compatible with Evinrude/Johnson/BRP 40-75 HP engines using the large gearcase, from 1968 and newer, and 85-140 HP engines, from 1969 and newer. A critical specification is the requirement for a 13-tooth spline setup with a 4-1/4″ gearcase diameter. The core of the kit is its one-piece rubber construction with integrated anodized aluminum splines, designed for durability and resistance to marine elements.

The 10 degrees of deflection built into the hub is a key functional specification. This feature is crucial for absorbing shock loads when shifting gears or encountering underwater obstructions, preventing abrupt jolts. The use of rubber and aluminum, eschewing plastics, directly addresses concerns about material degradation in a harsh marine environment. All necessary hardware and clear instructions are included, making it a complete package for replacement or initial installation.

Performance & Functionality

In terms of its primary function, this hub kit excels at eliminating propeller hub chatter and vibration. The most significant improvement I noticed was the reduction in that annoying resonance that often plagues older sterndrives. It performs its job of connecting the propeller to the driveshaft with a level of smoothness that was frankly surprising.

The 10 degrees of deflection is not just a marketing spec; it actively reduces the harshness when engaging gears, providing a more refined feel at the throttle. It also provides a cushion against minor impacts with submerged objects, offering a degree of protection to the propeller and drivetrain. Its ability to prevent spinning within the propeller hub is also paramount, ensuring that power transfer is consistent and efficient. The kit meets and exceeds expectations, particularly for its price point, offering a tangible upgrade in operational refinement.

Design & Ergonomics

The design of the RBX hub kit focuses on robust simplicity and effectiveness. The one-piece rubber construction is a smart choice, eliminating potential failure points from multiple bonded components. It feels substantial and well-made, designed to withstand the stresses of marine propulsion.

The anodized aluminum splines are precisely machined, ensuring a snug fit with the driveshaft and propeller. This attention to detail in the splines is critical for secure power transfer and longevity. While “ergonomics” might seem like an odd term for a sterndrive component, the ease of installation and the smooth feel it imparts to the boat’s operation are undeniable ergonomic benefits for the operator. There was no discernible learning curve; it simply worked as intended from the moment it was installed.

Durability & Maintenance

The projected durability of the Solas RBX-106 Rubex Hub Kit appears to be excellent, given the materials and construction. The one-piece rubber and anodized aluminum combination is inherently resistant to the corrosive elements found in marine environments. Unlike some other hub systems that use plastics that can become brittle or swell, this design seems built for the long haul.

Maintenance is virtually zero, beyond the basic engine and outdrive upkeep. Rinsing the propeller assembly with fresh water after use is sufficient to keep it clean and free from salt buildup. I haven’t encountered any specific wear points or potential failure concerns after my testing period. The design inherently protects the mating surfaces of the propeller and driveshaft from excessive wear.
