Breaking Down the Features of Solas RBX-203 Rubex Hub Kit For Yamaha 75 225 Hp, 1984 & Newer
Specifications
The Solas RBX-203 Rubex Hub Kit For Yamaha 75 225 Hp, 1984 & Newer is designed as a direct replacement for specific Yamaha outboard models. It features a one-piece rubber construction for the main body, which is crucial for its dampening capabilities. Integrated into this rubber are anodized aluminum splines, a critical detail that ensures a secure fit with the propeller shaft and prevents the dreaded plastic deterioration seen in some other systems. The kit is engineered to offer 10 degrees of deflection, a key specification that helps absorb shock when shifting gears or encountering underwater obstructions.
This specific deflection capability is vital because it allows for a controlled give, preventing harsh impacts from reaching the drivetrain. The anodized aluminum splines are a significant advantage over plastic, offering superior strength and resistance to corrosion and wear in the harsh marine environment. The elimination of plastic means these hubs are built to last, avoiding common failure points. The included hardware is typically stainless steel for maximum corrosion resistance.
Performance & Functionality
The primary job of the Solas Rubex hub kit is to provide a secure, vibration-free connection between the propeller and the outboard’s drive shaft. In this regard, it performs exceptionally well. The elimination of hub chatter and vibration is immediately noticeable, leading to a smoother, quieter operation, especially at idle and low speeds. This improved smoothness translates to a more enjoyable boating experience, reducing fatigue and increasing overall control.
The ability of the 10 degrees of deflection to reduce banging when shifting gears is another major strength. This controlled flex absorbs the initial shock, making forward and reverse transitions significantly gentler on the transmission. It also offers a degree of protection if the propeller strikes a submerged object, absorbing some of the impact before it can transfer further up the drivetrain. Compared to a rigid hub, this kit demonstrably improves the feel and longevity of the outboard. My experience suggests it not only meets but exceeds the functional expectations for a hub kit of this caliber.
Design & Ergonomics
The design of the Rubex hub kit is fundamentally functional, prioritizing durability and performance. The one-piece rubber construction with anodized aluminum splines is a testament to this.
