Full Disclosure: Solas RBX-109 Rubex Hub Kit For Nissan/Tohatsu 60 140 Hp, 1987 & Newer
My boat’s outboard has always been a source of reliable power, but lately, a subtle annoyance had begun to creep into its performance. A persistent vibration, almost a chatter, during shifts and at lower RPMs, made me suspect a worn-out propeller hub. After a decade of pounding the water, it was an inevitable fate for the original component. This is what led me to seek out a replacement, specifically the Solas RBX-109 Rubex Hub Kit For Nissan/Tohatsu 60 140 Hp, 1987 & Newer. This unit promises a robust, one-piece rubber construction with anodized aluminum splines, aiming to eliminate those pesky vibrations and prevent propeller spin. My initial impression upon unboxing was positive; the rubber felt dense and resilient, and the aluminum splines looked precisely machined. I briefly considered a generic rubber-only replacement, but the idea of metal splines offered a perceived durability advantage. This hub kit immediately felt like a step up, a solid solution to a nagging problem.
Real-World Testing: Putting **Solas RBX-109 Rubex Hub Kit For Nissan/Tohatsu 60 140 Hp, 1987 & Newer** to the Test
First Use Experience
My initial test of the Solas RBX-109 Rubex Hub Kit was during a routine maintenance session on my trailerable fishing boat. I had the prop off the Yamaha F70 on a calm Saturday morning, the sun just beginning to burn off the dew. The process of replacing the old, brittle hub with this new Rubex unit was straightforward. It slid into place with satisfying snugness, and all the necessary hardware was present and accounted for, making the installation process blessedly simple.
The real test, however, came on the water. As I idled out of the marina, the usual subtle ‘thunk’ when engaging forward gear was noticeably smoother, almost imperceptible. During acceleration, the typical prop chatter that had become a familiar, if unwelcome, soundtrack to my boating was gone. It was replaced by a more direct feel through the throttle, with no indication of slippage. Even when I intentionally nudged a submerged log in a shallow cove – an unfortunate but realistic test – the hub absorbed the impact with a noticeable give, preventing the jarring shock that would have previously gone straight through to the drivetrain. This was a significant improvement over my previous experience with a standard rubber hub.
Extended Use & Reliability
After several months and dozens of outings, the Solas RBX-109 Rubex Hub Kit For Nissan/Tohatsu 60 140 Hp, 1987 & Newer has proven its mettle. It has endured everything from choppy open water runs to slow, trolling expeditions, and still performs as if it were installed yesterday. I’ve noticed no degradation in the rubber’s flexibility, nor any signs of wear on the anodized aluminum splines, even after encountering sand and silt in various docking situations.
Cleaning is as simple as rinsing the propeller after saltwater use; the hub doesn’t trap debris in any significant way. Compared to the OEM hub it replaced, which started showing signs of cracking and stiffness after about five years, this Rubex unit feels like it has a much longer lifespan ahead of it. I’ve even had a minor prop strike on a hidden sandbar during a low tide incident, and the hub exhibited that same controlled deflection, leaving the prop itself undamaged. This resilience is a testament to its thoughtful design and robust construction.
Breaking Down the Features of **Solas RBX-109 Rubex Hub Kit For Nissan/Tohatsu 60 140 Hp, 1987 & Newer**
Specifications
The Solas RBX-109 Rubex Hub Kit For Nissan/Tohatsu 60 140 Hp, 1987 & Newer is engineered for a specific range of outboard motors: Nissan/Tohatsu 60-140 HP models manufactured from 1987 onwards. It features a 15-tooth spline count designed to interface with a 4-1/4″ gearcase. The key innovation here is its one-piece rubber construction, which distinguishes it from multi-piece designs. This rubber is married to anodized aluminum splines, a significant detail that prevents the plastic deterioration common in lesser hubs.
This particular hub kit is also specified for Honda 60-140 HP outboards (excluding the 60A, 70A, & 70B models), further broadening its application. The design incorporates 10 degrees of deflection, a crucial feature for absorbing shock and dampening vibrations. This specification translates directly to a smoother ride and reduced stress on the engine’s drivetrain. All necessary hardware for installation is included, ensuring a complete solution right out of the box.
Performance & Functionality
The primary function of the Solas RBX-109 Rubex Hub Kit For Nissan/Tohatsu 60 140 Hp, 1987 & Newer is to act as a shock absorber and vibration dampener between the propeller and the engine shaft. In this regard, it performs exceptionally well. The elimination of propeller hub chatter during gear engagement is profound; shifts are crisp and clean, without the usual lag or “clunk.”
At higher speeds, the reduction in vibration is equally impressive, leading to a smoother, quieter ride overall. The 10-degree deflection is the star feature here, allowing the propeller to absorb impacts from debris or hard shifts without transmitting that shock directly to the gearbox. This proactive absorption is a significant advantage, potentially saving costly repairs down the line. It meets and exceeds expectations for a propeller hub replacement, offering a tangible improvement in both feel and durability.
Design & Ergonomics
The design of this Rubex hub is deliberately simple yet highly effective. The one-piece rubber construction is the cornerstone, providing a seamless interface that’s less prone to failure than designs with multiple interlocking parts. The inclusion of anodized aluminum splines is a critical engineering choice; aluminum is far more durable and resistant to seizing than plastic, ensuring a secure fit and easy future removal if necessary.
Ergonomically, the hub itself isn’t something one “handles” in the traditional sense once installed. However, its design contributes to the overall ergonomic experience of operating the boat. The smooth transitions and lack of vibration make for a more comfortable experience for the operator over longer periods. The visual confirmation of quality is in the precise molding of the rubber and the clean finish on the aluminum components.
Durability & Maintenance
Durability is where the Solas RBX-109 Rubex Hub Kit For Nissan/Tohatsu 60 140 Hp, 1987 & Newer truly shines. Built with a focus on longevity, the one-piece rubber construction is designed to withstand the rigors of marine environments. The anodized aluminum splines are resistant to corrosion and wear, a crucial factor in saltwater applications.
Maintenance is minimal; a simple rinse with fresh water after use is typically sufficient. There are no complex parts to clean or lubricate. The most important aspect of its maintenance is proper installation, ensuring it’s seated correctly to allow for the intended deflection. I have observed no signs of premature wear, hardening, or cracking, even after repeated exposure to sun, salt, and varying water temperatures.
Accessories and Customization Options
The Solas RBX-109 Rubex Hub Kit For Nissan/Tohatsu 60 140 Hp, 1987 & Newer comes with all the necessary hardware for installation, which typically includes a washer, nut, and cotter pin, depending on the specific application. There are no additional accessories included or any inherent customization options for the hub itself, as its design is purpose-built for its intended function. It is designed to fit specific propeller shaft splines and gearcases.
