Let’s Dive into Solas RBX-101 Rubex Hub Kit For Evinrude/Johnson/Brp 90 300 Hp, 1976 90 15 Tooth 4.75″ Gearcase
The Solas RBX-101 Rubex Hub Kit isn’t the sexiest piece of gear, but it’s absolutely vital for anyone running a classic Evinrude, Johnson, or BRP outboard in the 90-300 HP range. This hub kit, designed specifically for models from 1976-1990 with a 15-tooth spline and 4.75″ gearcase, as well as OMC/Cobra/King Cobra models from 1991-1994, is the unsung hero preventing catastrophic propeller failure and ensuring smooth power transfer.
My journey to the Solas RBX-101 started with a frustrating vibration in my vintage 1986 Johnson 150. The old rubber hub in my existing prop had deteriorated, causing excessive chatter and making it feel like the engine was about to shake itself apart at higher RPMs. Replacing the entire propeller seemed wasteful when the blades were still in great shape.
Unboxing the Solas RBX-101, I was immediately impressed by the robust construction. The one-piece rubber design felt significantly sturdier than the brittle, cracked remnants of my old hub. The anodized aluminum splines looked precisely machined, promising a tight, secure fit.
I considered a few other hub kits, mainly those offered by Michigan Wheel and Turning Point Propellers. Ultimately, I chose the Solas RBX-101 because of its reputation for durability and its specific compatibility with my older Johnson outboard, plus the Solas name is synonymous with quality in the marine propeller world.
My first impression was relief; I hoped this seemingly small part would solve a very annoying and potentially damaging problem. The initial quality of materials instilled confidence.

First Use Experience
The real test came on Lake Michigan, where I frequently run my boat for fishing trips. After installing the Solas RBX-101, which was a straightforward process thanks to the included instructions, I eagerly launched the boat.
The difference was immediately noticeable. The vibration that had plagued me for months was gone, replaced by a smooth, confident power delivery. Even under heavy throttle, the engine felt more responsive, and the boat planed more quickly. There was no more concerning chatter coming from the prop.
There were no initial issues or surprises – just a smoother, quieter ride. The Solas RBX-101 performed exactly as advertised.
Extended Use & Reliability
After a full season of use, which included numerous fishing trips and recreational boating, the Solas RBX-101 has held up remarkably well. I’ve put roughly 100 hours on the engine since installation, and the hub kit shows no signs of wear or deterioration.
The rubber remains pliable, and there is no indication of slippage or vibration, even under the stress of pulling skiers or navigating choppy water. The anodized aluminum splines still look new. Regular inspection is easy; just pull the prop after each outing and check for wear.

Specifications
- Compatibility: Designed for Evinrude/Johnson/BRP 90-300 HP (1976-1990) with 15 tooth spline and 4-3/4″ gearcase, and OMC/Cobra/King Cobra (1991-1994) with 15 tooth spline and 4-3/4″ gearcase. This specific fitment ensures proper engagement and prevents damage to the propeller shaft.
- Construction: One-piece rubber construction with anodized aluminum splines. The rubber dampens vibrations, while the aluminum splines provide strength and corrosion resistance.
- Deflection: Offers 10 degrees of deflection. This absorbs shock from shifting gears and impacts with submerged objects, reducing stress on the engine and drive train.
