Let’s Dive into Solas RBX-114 Rubex Hub Kit For Select Mercury/Mariner/MerCruiser/Force 25 80 Hp
The Solas RBX-114 Rubex Hub Kit isn’t exactly the kind of thing that gets your heart racing, but when your outboard’s propeller starts rattling like a tin can full of bolts, you quickly realize how essential a good hub system is. This kit, manufactured by Solas, is designed as a direct replacement for the vulnerable rubber hubs in select Mercury, Mariner, MerCruiser, and Force outboards ranging from 25 to 80 horsepower. The promise of reduced vibration, less shifting clunk, and protection against prop damage definitely piqued my interest, given my years battling the harsh marine environment.
My own experience with boat maintenance goes back to my teenage years, helping my father with his small fishing boat, and that experience taught me a thing or two about the importance of a well-maintained propulsion system. The existing hub on my older Mercury 50hp outboard was showing its age. The old hub displayed excessive play and vibration that made me concerned about its reliability while far offshore.
Upon receiving the Solas RBX-114, I was immediately struck by its robust appearance. The one-piece rubber construction felt denser and more resilient than the aging, cracked rubber on my existing hub, while the anodized aluminum splines exuded quality. Compared to cheaper aftermarket hubs, this one just felt right in my hands.
Having previously considered a Quicksilver hub kit and a Michigan Wheel XHS hub, I ultimately chose the Solas RBX-114 based on its reputation for balancing durability and vibration dampening, as well as positive reviews from fellow boaters in online forums. My first impression was definitely positive – this looked like a well-engineered solution, not just a cheap band-aid.
Real-World Testing: Putting Solas RBX-114 Rubex Hub Kit For Select Mercury/Mariner/MerCruiser/Force 25 80 Hp to the Test
First Use Experience
I installed the Solas RBX-114 Rubex Hub Kit on my Mercury 50hp outboard, which is mounted on my 16-foot aluminum fishing boat. The initial test took place on a local reservoir known for its choppy conditions and occasional submerged debris. After installation, the most immediate and noticeable change was a significant reduction in vibration at idle and low speeds.
Previously, shifting into gear resulted in a pronounced “clunk” and shudder; the new hub noticeably dampened the impact. Even running at planing speed, the overall feel was smoother and quieter compared to the old, worn hub. This improvement was especially noticeable when navigating through some mildly choppy water.
Extended Use & Reliability
After several months of regular use (approximately 50 hours on the water), the Solas RBX-114 has performed admirably. There are no visible signs of wear or deterioration, even after a couple of minor prop strikes against submerged logs. The improved shifting smoothness has remained consistent.
Maintenance has been simple: I just inspect the hub visually when I change the lower unit oil. In comparison to my prior experiences with the stock rubber hub, which required replacement every season or two due to wear and tear, the Solas unit seems far more durable and reliable. I am happy to report this hub kit is exceeding my expectations.
Breaking Down the Features of Solas RBX-114 Rubex Hub Kit For Select Mercury/Mariner/MerCruiser/Force 25 80 Hp
Specifications
The Solas RBX-114 Rubex Hub Kit is engineered as a direct replacement hub for select Mercury/Mariner/MerCruiser/Force outboards ranging from 25 to 80 horsepower. The key specifications include a 13-tooth spline, designed to mate perfectly with the propeller shaft of compatible outboards, and the hub is intended for outboards with a 3-1/4″ gearcase. It is specifically designed for various models including: 25 HP Bigfoot (1999-05), 30 HP Bigfoot (2010 and Newer), 30HP (2 & 4-Stroke) (1994-05), 30 HP (Sea Pro/Marathon) (1994 & Newer), 35 HP (1984-89), 402 & 500 Models (1974-84), 40 – 50 HP (2 & 4-Stroke,Not Bigfoot) (1997 & Newer), 45 HP (1986-1989), 48 HP (Mariner) (All Years), 55 HP (Sea Pro/Marathon) (1995 & Newer), 60 HP (Mariner) (1976), 60 HP (2 & 4-Stroke, Not Bigfoot or Sea Pro/Marathon) (1978 & Newer), 65 HP (Includes Model 650) (1972-1976), 70 HP (Includes Model 700) thru (1983), 80 HP (Mariner) (1977).
These specifications are critical because they ensure proper fit and function, maintaining optimal power transfer from the engine to the propeller. The 10-degree deflection designed into the hub allows for some give when shifting gears or striking underwater obstacles, protecting the propeller and lower unit from more severe damage.
Performance & Functionality
The Solas RBX-114 Rubex Hub Kit performs its intended job exceptionally well: reducing vibration, improving shifting smoothness, and protecting the propeller. The most noticeable improvement is the dampening of vibration, particularly at lower RPMs, which makes for a more comfortable and less fatiguing boating experience. The anodized aluminum splines ensure a secure and durable connection to the propeller shaft, minimizing slippage and maximizing power transfer.
A potential weakness, though minor, is that the hub’s dampening effect might slightly reduce the “feel” of the engine, which some experienced boaters might prefer. However, the benefits of reduced vibration and smoother shifting far outweigh this minor drawback. The product meets and exceeds expectations by providing a noticeable improvement in overall boat handling and engine performance.
Design & Ergonomics
The Solas RBX-114 features a one-piece rubber construction with anodized aluminum splines. The rubber construction appears robust and resistant to the harsh marine environment. The hub is not exactly something you “handle” regularly, installation is straightforward, and the design ensures a secure and reliable fit.
There is no significant learning curve associated with using the Solas RBX-114. Installation is similar to replacing a standard rubber hub.
Durability & Maintenance
The Solas RBX-114 Rubex Hub Kit is designed for long-term durability. The rubber compound is resistant to saltwater, UV exposure, and temperature extremes, and the anodized aluminum splines resist corrosion. Maintenance is minimal.
Replacement is easy. The old hub must be pressed out of the prop, and the new hub pressed in. Basic tools, like a shop press and appropriate size prop shaft support tool, are required.
Accessories and Customization Options
The Solas RBX-114 Rubex Hub Kit comes as a standalone unit with all necessary hardware for installation. It is not typically customized. Because it uses a standard size and spline count, it is fully compatible with a wide variety of propellers designed for compatible Mercury, Mariner, MerCruiser, and Force outboards.
