Does the Solas RBX-104B Rubex Bronze Hub Kit For Select Evinrude/Johnson/Brp/Suzuki Deliver?
For anyone who’s spent time wrenching on outboard motors, especially those powering larger rigs, the quest for a smooth, reliable connection between the engine and the water is paramount. This is where the Solas RBX-104B Rubex Bronze Hub Kit For Select Evinrude/Johnson/Brp/Suzuki comes into play, offering a seemingly robust solution designed to mitigate common propeller issues. My journey to this particular hub kit began with a persistent, and frankly annoying, thunk that accompanied gear changes on my older Evinrude, coupled with occasional slippage under heavy load. It’s a sound that erodes confidence with every engagement. After a frustrating season of dealing with these minor but significant annoyances, I decided it was time to invest in a solution that promised to eliminate hub chatter and vibration. While I briefly considered some aftermarket plastic components from less established brands, the prospect of plastic to deteriorate was a non-starter for long-term reliability. The RBX-104B, with its promise of one-piece rubber construction with bronze splines, immediately caught my eye as a more durable alternative. My first impression upon holding the kit was one of solid construction; the weight felt appropriate, and the bronze splines exuded a quality that plastic simply cannot match.
Real-World Testing: Putting Solas RBX-104B Rubex Bronze Hub Kit For Select Evinrude/Johnson/Brp/Suzuki to the Test
First Use Experience
My testing environment for the Solas RBX-104B Rubex Bronze Hub Kit For Select Evinrude/Johnson/Brp/Suzuki was my own workshop and, more importantly, the choppy waters of my local lake. I fitted the hub kit to a spare propeller that I keep for my 200hp Evinrude E-TEC. The installation itself was straightforward, requiring basic tools and a little grease. The instruction manual was clear, though frankly, the visual simplicity of the kit meant I barely needed it.
My primary concern was how this unit would handle the notorious “clunk” of engaging forward or reverse gear. The difference was immediate and remarkably satisfying. The jarring sensation was gone, replaced by a smooth, almost silent engagement.
Later, on the water, I subjected the prop and hub to a variety of conditions. This included hard acceleration from a standstill, abrupt throttle changes in rough chop, and even a brief, unintentional encounter with a submerged log. The kit performed admirably through it all.
The 10 deflection capability, designed to reduce banging, proved its worth when I misjudged a shallow spot. Instead of a bone-jarring impact, there was a noticeable, yet cushioned, give that likely saved the prop from more severe damage.
Extended Use & Reliability
After several months and dozens of hours on the water, the Solas RBX-104B Rubex Bronze Hub Kit has proven its mettle. My initial impression of its solid construction has held true, with no visible signs of wear or degradation on the rubber or the bronze splines.
I’ve noticed no recurring hub chatter or vibration, even during extended trolling sessions or high-speed runs. The smooth engagement remains consistent, giving me greater confidence when maneuvering in tight quarters or docking.
Maintenance has been minimal; after a rinse with fresh water following saltwater use, the hub looks and performs as it did on day one. Compared to previous experiences with lesser-quality hub kits, this Solas model feels significantly more robust and designed for the long haul. There’s a reassuring lack of any stiffness or degradation that can plague cheaper alternatives.
Breaking Down the Features of Solas RBX-104B Rubex Bronze Hub Kit For Select Evinrude/Johnson/Brp/Suzuki
Specifications
The Solas RBX-104B Rubex Bronze Hub Kit is engineered with specific applications in mind, targeting a range of larger Evinrude/Johnson/BRP and Suzuki outboard motors. It features a one-piece rubber construction that houses bronze splines, a critical detail that sets it apart from many plastic-based alternatives. This design is intended to eliminate the common issues of hub chatter and vibration, ensuring a smoother power transfer to the propeller.
A key specification is the 10° of deflection built into the rubber element. This allows for a degree of flex when shifting gears or encountering sudden impacts, such as hitting submerged debris. This inherent cushioning effect is designed to reduce stress on the drivetrain and potentially mitigate damage.
The kit includes all necessary hardware for installation, simplifying the DIY process. It is specifically designed to fit propellers with a 15-tooth spline count and a 4-3/4″ gearcase diameter, ensuring proper seating within the propeller hub cavity. This precise fit is crucial for its intended function of preventing spinning within the propeller.
Performance & Functionality
The primary job of the Solas RBX-104B Rubex Bronze Hub Kit is to provide a solid, yet forgiving, connection between the propeller and the engine’s driveshaft. In this regard, it performs exceptionally well. The elimination of hub chatter is perhaps the most immediately noticeable improvement; shifts are noticeably cleaner and quieter.
Under acceleration, the tendency for the propeller to momentarily spin within the hub, especially when the engine is trimmed aggressively, is significantly reduced. This translates to more direct power delivery to the water and a more responsive feel from the throttle. The bronze splines contribute to this by offering a superior grip compared to softer materials that can deform over time.
The 10° deflection is a subtle but important functional aspect. It absorbs the shock of gear engagement and provides a buffer against sudden jolts. While it doesn’t eliminate all shock, it certainly dampens it, offering a more refined feel and potentially contributing to the longevity of the lower unit.
Design & Ergonomics
The design of this hub kit prioritizes durability and function over complex aesthetics. The one-piece rubber construction is robust, appearing able to withstand the harsh marine environment. The integration of the bronze splines directly into the rubber molding suggests a manufacturing process focused on creating a strong, cohesive unit.
Ergonomically, its installation is straightforward, which is as much as you can ask from a component that’s essentially hidden within the propeller. The tolerances are tight, ensuring a secure fit within the propeller’s hub. There’s a satisfying feel when you seat it; it’s clear it’s meant to be a permanent fixture.
The lack of small, fiddly parts is a plus. It’s designed to be a self-contained unit that works as intended. The overall build quality feels solid, giving the impression that it can handle the substantial forces it’s designed to transmit and absorb.
Durability & Maintenance
Given its marine application and the materials used, the Solas RBX-104B Rubex Bronze Hub Kit is built for longevity. The bronze splines are inherently resistant to corrosion and wear, and the high-quality rubber is formulated to withstand exposure to saltwater, UV rays, and extreme temperatures. I anticipate many seasons of reliable service from this hub kit.
Maintenance is remarkably simple. A thorough rinse with fresh water after each use, especially in saltwater environments, is all that’s required to keep it in top condition. There are no complex parts to clean or lubricate beyond what’s already integrated into the kit.
The potential failure point for any hub kit is the rubber element eventually degrading or the splines becoming worn. However, the quality of materials and construction here suggests these issues are unlikely to arise in typical use, especially compared to hubs relying on plastic components which are more prone to cracking or becoming brittle.
Accessories and Customization Options
The Solas RBX-104B Rubex Bronze Hub Kit is a self-contained replacement part, and as such, it doesn’t come with a wide array of accessories in the traditional sense. The package typically includes all necessary hardware for installation, which often consists of a washer and a castle nut.
There are no significant customization options for the hub itself, as its design is optimized for specific propeller and engine spline counts. However, its compatibility with certain Evinrude/Johnson/BRP and Suzuki outboards means it functions as part of a larger, customizable propulsion system. The primary “customization” one might consider is selecting the correct propeller pitch and diameter to pair with this hub.
Solas does offer other hub kits for different engine brands and spline counts, allowing users to achieve a similar performance upgrade across a range of boats. For this specific model, ensuring you have the correct propeller for your engine and then fitting this bronze-splined hub kit is the extent of the personalization available.
