Let’s Dive into Solas RBX-123 Rubex Hub Kit For Mercury/Mariner/MerCruiser With 1.25″ Shaft 19 Tooth Spline
The Solas RBX-123 Rubex Hub Kit isn’t exactly the kind of gear that gets the pulse racing like a new rifle or a high-tech scope. However, as anyone with serious time on the water knows, the unsung heroes that keep our boats running smoothly are just as crucial. This particular kit, designed for Mercury, Mariner, and MerCruiser engines with a 1.25″ shaft and 19-tooth spline, promises to be a robust solution for preventing propeller slippage and minimizing vibration.
My own wakeboarding boat, a ’98 MasterCraft with a MerCruiser 350, had started exhibiting some concerning hub chatter, especially when pulling heavier riders. The old rubber hub was clearly on its last legs, causing a noticeable loss of power and some pretty jarring vibrations at higher RPMs. I needed a reliable replacement that could handle the stress of constant starts and stops, and the Solas RBX-123 seemed like a solid contender based on its reputation for durability and performance.
Unboxing the Solas RBX-123, I was immediately struck by the quality of the components. The rubber felt dense and resilient, and the anodized aluminum splines looked precisely machined. The kit felt noticeably heavier and more substantial than the OEM hub I removed. Initial impressions suggest this is a serious upgrade, built to withstand the rigors of demanding watersports.
I considered the Quicksilver Flo-Torq II hub kit and the Michigan Wheel XHS hub kit as alternatives. Ultimately, I chose the Solas RBX-123 due to the Solas brand’s reputation for quality in the aftermarket marine parts industry. Also, the Rubex design, with its emphasis on eliminating chatter and vibration through a one-piece rubber construction, was highly appealing. I was cautiously optimistic, hoping this kit would restore my boat’s performance and eliminate those annoying vibrations.
Real-World Testing: Putting Solas RBX-123 Rubex Hub Kit For Mercury/Mariner/MerCruiser With 1.25″ Shaft 19 Tooth Spline to the Test
First Use Experience
My first opportunity to test the Solas RBX-123 was on a weekend wakeboarding trip to Lake Travis in central Texas. The conditions were typical for a Texas summer – hot, sunny, and with a slight chop on the water. Installation was straightforward, thanks to the included instructions and the readily available online tutorials.
Immediately upon starting the engine, I noticed a significant reduction in vibration compared to the old hub. Out on the water, the improvement was even more pronounced. Acceleration felt smoother and more responsive, and the annoying hub chatter that had plagued my previous outings was completely gone. Pulling wakeboarders felt effortless, and the boat maintained its speed with much less strain on the engine.
Extended Use & Reliability
After several months of regular use, the Solas RBX-123 continues to perform flawlessly. There are no signs of wear or tear, and the hub remains firmly in place. I’ve subjected it to some pretty demanding conditions, including choppy water, heavy loads (multiple riders), and extended periods of high-speed operation.
Maintenance has been minimal, requiring only occasional visual inspection and a light greasing of the splines during propeller changes. Compared to the OEM hub, which seemed to degrade quickly and required frequent replacement, the Solas RBX-123 has proven to be far more durable and reliable. It has definitely exceeded my expectations and has given me peace of mind knowing that my boat’s propulsion system is solid and dependable.
