Turning Point Propellers Hub Kit 705 Review

The Turning Point Propellers Hub Kit 705: First Use to Final Thoughts

The Turning Point Propellers Hub Kit 705 is a vital component for any boater with a compatible Yamaha engine, specifically those requiring a 15-tooth spline shaft and a 4.75″ gearcase. This system acts as the crucial interface between the engine’s drivetrain and the propeller, designed for durability and enhanced lower unit protection. It’s engineered to fit Hustler and Express Series propellers, offering a robust solution for powerplants of 200hp and above.

My need for this specific hub kit arose after a particularly aggressive encounter with submerged debris during a late-season fishing trip. The prop strike was significant, and while the propeller absorbed the brunt of the impact, it became clear that the existing hub system had sustained damage, leading to noticeable vibration and a nagging concern about potential drivetrain stress. Replacing just the propeller wasn’t an option; a compromised hub could lead to far more catastrophic (and expensive) failures down the line.

Upon receiving the Turning Point Propellers Hub Kit 705, my initial impression was one of solid construction. The one-piece hub design, featuring glass-filled nylon over marine bronze splines, felt considerably more robust than some older, multi-part sleeve-and-spline systems I’ve encountered. The absence of press-fit rubber also gave me confidence in its long-term integrity.

I briefly considered a generic, no-name replacement, but the thought of compromising the protection for my Yamaha’s lower unit quickly dismissed that idea. The potential savings were minuscule compared to the risk of gearcase damage. My first impression was a quiet sense of relief, knowing I had a seemingly well-engineered solution to address the issue.

Real-World Testing: Putting Turning Point Propellers Hub Kit 705 to the Test

First Use Experience

My testing environment was precisely where this hub kit is designed to shine: out on the water. I installed the kit in my workshop, which, while clean, doesn’t replicate the challenging marine conditions this component will face. The installation itself was straightforward, aligning with the expectations set by the product’s clear design.

Performance in varying conditions was my primary focus. Over the next few weeks, I subjected the Turning Point Propellers Hub Kit 705 to a range of scenarios: aggressive acceleration from a dead stop, high-speed runs in choppy water, and slower trolling speeds where any existing vibration would be most noticeable. I also made a point to navigate areas known for submerged hazards, albeit with increased caution.

The ease of use was remarkable; after understanding the initial spline alignment, the installation and subsequent operation felt entirely intuitive. The most significant positive surprise was the immediate elimination of the vibration that had plagued me post-prop strike. It was a tangible difference, indicating the hub was effectively absorbing and dampening torsional forces.

Extended Use & Reliability

After several months and countless hours on the water, the Turning Point Propellers Hub Kit 705 has held up exceptionally well. It remains the cornerstone of my propeller setup, performing its duties without any noticeable degradation. There are absolutely no signs of wear and tear on the hub itself; no cracks, no stiffness, and critically, no performance drop.

Maintenance has been virtually non-existent, which is a testament to its robust, corrosion-resistant materials. A simple rinse with fresh water after saltwater use is all that’s required. I haven’t had to perform any specific care beyond that.

Compared to previous experiences with less advanced hub systems, this Turning Point offering is in a different league. Older systems, particularly those relying on pressed-in rubber, would often show signs of fatigue or failure after significant impacts or prolonged stress. This particular hub kit seems to truly embody its “Lifetime Warranty Hub” claim, instilling a level of confidence that’s hard to quantify but incredibly valuable.

Breaking Down the Features of Turning Point Propellers Hub Kit 705

Specifications

The Turning Point Propellers Hub Kit 705 is a meticulously engineered system designed for specific Yamaha outboard applications. It features a 15-Tooth Spline Hub, which is critical for proper engagement with compatible Yamaha 200+hp engines that possess a 4.75″ Gearcase. The manufacturer, Turning Point Propellers, utilizes a unique one-piece hub construction that is over-molded with glass-filled nylon onto durable marine bronze splines.

This design choice is paramount because it directly addresses common failure points found in older “sleeve and spline” or rubber-based hub systems. The marine bronze ensures excellent corrosion resistance and a secure, non-slipping interface with the engine’s driveshaft. The glass-filled nylon provides impact absorption without compromising structural integrity. The kit comes in a Black color, a common aesthetic for engine components.

These specifications translate directly into real-world benefits. The 15-tooth spline count ensures it mates perfectly with the designated Yamaha engines, preventing slippage and power loss. The 4.75″ gearcase specification guarantees correct fitment and alignment, which is crucial for optimal propeller performance and reducing stress on the lower unit. The one-piece construction, a key patented feature (US Patent #6,471,481, #6,685,432, #7,717,678 and worldwide patents pending), is a significant upgrade over traditional methods, eliminating potential weak points where components could separate or wear excessively.

Performance & Functionality

The primary function of the Turning Point Propellers Hub Kit 705 is to serve as a robust and protective intermediary between the propeller and the engine’s drivetrain. Its main job is to absorb the shock of engagement, dampen vibrations, and, crucially, shear or allow the propeller to spin independently under extreme impact to protect the more expensive drivetrain components. In this regard, it performs exceptionally well.

Its strengths lie in its enhanced lower unit protection and the near elimination of propeller vibration and chatter. Post-installation, the boat felt significantly smoother, especially during acceleration and deceleration. The ability for the hub to be re-usable most of the time after a prop strike, as stated by the manufacturer, is a massive functional advantage; it means that minor incidents don’t automatically necessitate a complete replacement of the hub assembly.

A slight area for potential improvement, though arguably inherent to its protective design, is the possibility of it sacrificing itself too readily. However, this is a trade-off most serious boaters will gladly accept. The Lifetime Warranty Hub offers peace of mind, even if the propeller is destroyed during an incident, the hub’s protection is guaranteed.

Design & Ergonomics

The design of the Turning Point Propellers Hub Kit 705 is elegantly simple yet technically advanced. The use of high-quality materials like marine bronze splines and glass-filled nylon results in a product that feels substantial and durable. The finish is smooth, and the overall build quality speaks to its intended marine environment.

Ergonomically, the hub is designed for straightforward installation and reliable operation once mounted. There’s no “grip” to speak of in the traditional sense, but its internal splines and the outer hub’s compatibility with various propeller series mean it integrates seamlessly into the propeller assembly. The one-piece construction contributes to a clean, uncompromised profile.

Practical design details like the corrosion-resistant materials are evident and critically important for longevity in saltwater. The clear differentiation between the engine-side splines and the propeller-mating surface ensures correct assembly and function. It’s a design that prioritizes function and durability above all else.

Durability & Maintenance

Based on its construction and materials, the Turning Point Propellers Hub Kit 705 is built for exceptional durability. The Lifetime Warranty Hub is a strong indicator of the manufacturer’s confidence in its longevity under normal operational use. The corrosion-resistant materials are specifically chosen to withstand the harsh marine environment, resisting saltwater, UV exposure, and constant flexing.

The robust construction means that unlike some rubber-based hubs, you won’t face issues like cracking or hardening over time.

Potential failure points, from my experience and the product’s design, are minimal. The unique patented one-piece design is engineered to eliminate failures commonly seen in multi-part “sleeve and spline” designs. The most likely scenario for replacement would be after a severe prop strike where the hub is designed to shear, but even then, its warranty coverage is a significant advantage.

Accessories and Customization Options

The Turning Point Propellers Hub Kit 705 itself is a component, not a standalone item that typically comes with numerous accessories. However, its key feature is its outer hub compatibility with different props. This means you can pair this single hub kit with a variety of Hustler and Express Series Propellers from Turning Point, offering a degree of customization in propeller selection without needing a new hub.

While the hub kit doesn’t come with additional parts like needles or tips (as it’s not a fluid dispensing device), its compatibility with specific propeller lines is its primary form of customization. This allows users to select the propeller pitch, diameter, and blade count that best suits their vessel and engine, all while utilizing this single, robust hub system. The ability to never buy another hub kit system again (as per the manufacturer’s claim for the warranty) emphasizes its role as a long-term, adaptable solution rather than a consumable part.
