Review YAMAHA Propeller Outboard 60-115hp Sds Spline Rh fits TALON SS 2013–2021

The **Yamaha D-ST-21 (13" x 21") Talon Propeller** is a high-performance, precision-engineered propeller designed exclusively for Yamaha outboard engines in the **60 115 horsepower SDS (Single Drive Shaft) series**, featuring a **15-spline shaft connection**. This propeller exemplifies Yamaha s commitment to innovation and efficiency, combining cutting-edge aerodynamics with durable construction to deliver unmatched thrust, fuel economy, and handling responsiveness. The **Talon series** is engineered with Yamaha s proprietary **Variable Pitch (VP) technology**, allowing the propeller blades to adjust dynamically to changing load conditions, ensuring optimal performance whether cruising at steady speeds or accelerating quickly. The **13-inch diameter** provides a balanced blend of power and efficiency, making it ideal for mid-sized boats ranging from fishing vessels and sportboats to utility and recreational crafts. The **21-inch pitch** enhances forward thrust while maintaining smooth operation, reducing strain on the engine and improving overall fuel efficiency critical for long-range excursions or daily use.

Crafted from **high-grade aluminum alloy**, the D-ST-21 is built to withstand the rigors of saltwater corrosion, saltwater corrosion inhibitors, and frequent use, with a **hard-anodized finish** that resists pitting and wear. The **hydrodynamic blade design** features sharp, optimized edges that minimize cavitation and vibration, enhancing both comfort and longevity. The **three-blade configuration** strikes an ideal balance between power and efficiency, reducing drag while maximizing acceleration and top-end speed. This propeller is particularly well-suited for applications where **quick acceleration, precise control, and fuel savings** are priorities, such as in fishing boats where rapid maneuverability is essential or in performance cruisers where smooth, efficient operation is key.

For Yamaha outboard owners seeking a **versatile, high-performance propeller** that adapts seamlessly to their driving style, the D-ST-21 Talon is an excellent choice. Its **15-spline compatibility** ensures a secure, vibration-dampening connection to the engine, while its **adjustable pitch characteristics** allow for fine-tuning of performance based on load, boat weight, and intended use. Whether tackling rough water, towing trailers, or simply enjoying a leisurely day on the water, this propeller delivers **reliable power, fuel efficiency, and handling precision** all hallmarks of Yamaha s reputation for engineering excellence. Proper installation and regular maintenance will further extend its lifespan, ensuring years of dependable performance for the discerning boater.

### **Pros and Cons of buying a Yamaha D-ST-21 (13" or 21" Talon Propeller) for 60 115HP SDS Outboards (15 Spline, RH)**

#### **Pros:**

1. **Optimized for SDS Outboards**

The D-ST-21 is specifically designed for Yamaha s SDS (Super Drive System) outboards, which means it s engineered to work efficiently with the drivetrain s power delivery. This reduces wear on the lower unit and improves overall performance.

2. **High Efficiency at Low to Mid RPMs**

The Talon series propellers are known for their efficiency in the 2,000 3,500 RPM range, which is ideal for cruising and leisure boating. This makes them well-suited for outboards in the 60 115HP range, where smooth, fuel-efficient operation is often prioritized.

3. **Reduced Cavitation and Improved Fuel Economy**

The D-ST-21 s design minimizes cavitation (the formation of vapor bubbles that can damage the propeller and reduce efficiency). This leads to better fuel economy and less stress on the engine over time.

4. **Durable Construction**

Yamaha propellers are built with high-quality materials, including stainless steel blades, which resist corrosion and wear better than aluminum or lower-grade steel. This extends the propeller s lifespan, especially in saltwater conditions.

5. **Quiet Operation**

The Talon series is designed to reduce noise and vibration, providing a smoother ride. This is particularly beneficial for fishing or leisure boating where comfort is important.

6. **Compatibility with 15 Spline Shafts**

The 15-spline shaft is a common drivetrain for mid-range Yamaha outboards, and the D-ST-21 is engineered to work seamlessly with this setup, ensuring proper torque transfer and longevity.

7. **Versatile Performance**

The 13" and 21" variants offer different pitch options (likely 21" for higher speeds and 13" for better acceleration and fuel efficiency). This flexibility allows boat owners to choose based on their specific needs whether prioritizing speed, towing capacity, or fuel savings.

8. **Easy to Install and Maintain**

Yamaha propellers are designed for straightforward installation, and their durable construction means they require less frequent maintenance compared to cheaper alternatives.

#### **Cons:**

1. **Higher Upfront Cost**

Yamaha propellers are premium products, and the D-ST-21 is no exception. They cost significantly more than generic or aftermarket propellers, which may be a barrier for budget-conscious buyers.

2. **Limited Customization**

Unlike some aftermarket propellers that offer a wide range of pitch and diameter options, the D-ST-21 comes in specific configurations (13" and 21"). If your boat s needs fall outside these options, you may need to compromise or invest in a different model.

3. **Potential Overkill for Light-Duty Use**

If you primarily use your boat for calm, low-speed cruising (e.g., lake fishing with minimal towing), a slightly smaller or lower-pitch propeller might be more efficient and cost-effective. The D-ST-21 is optimized for a broader range of conditions, which may not always be necessary.

4. **Saltwater Corrosion Risk (If Not Properly Maintained)**

While the stainless steel construction is durable, saltwater can still cause corrosion over time if the propeller isn t cleaned and treated regularly. This requires additional maintenance effort compared to freshwater use.

5. **Weight**

Stainless steel propellers are heavier than aluminum ones, which can slightly increase the boat s trim and handling dynamics, though the difference is usually negligible for most outboards in this range.

6. **Limited Availability of Replacement Parts**

If the propeller sustains damage (e.g., a bent blade), finding exact replacements may be harder than with more common propeller brands. However, Yamaha s reputation ensures reliability, so this is less of an issue for most owners.

---

### **Conclusion and Recommendation**

The **Yamaha D-ST-21 (13" or 21" Talon propeller)** is an excellent choice for owners of 60 115HP SDS outboards with a 15-spline shaft, particularly if you prioritize efficiency, durability, and smooth operation. Its optimized design for Yamaha s drivetrain reduces wear, improves fuel economy, and enhances overall performance across a range of conditions. The premium build quality and reduced cavitation make it a reliable long-term investment, especially for those who use their boats in varied environments (e.g., fishing, cruising, or light towing).

**However**, if your primary use involves very low-speed operations (e.g., trolling) or if budget constraints are a concern, you might consider a slightly smaller or lower-pitch propeller. Additionally, if you frequently tow heavy loads or require maximum speed, the 21" variant would be the better pick, while the 13" could be ideal for fuel efficiency and acceleration.

**Final Recommendation:**

For most **60 115HP SDS outboards** in the 15-spline RH category, the **Yamaha D-ST-21 Talon propeller is the best choice** due to its balance of performance, durability, and compatibility. If you re unsure between the 13" and 21", test the boat s current propeller performance if you frequently cruise at moderate speeds with occasional towing, the 21" is likely the better all-around option. If you mostly prioritize fuel efficiency and low-speed maneuverability, the 13" could be sufficient. Always pair this with proper maintenance (regular cleaning, lubrication, and inspection) to maximize its lifespan.

Details:

See attached receipt. Ran 50 6000 rpm on a 15 Whaler with new F70 Yamaha. 100 hrs on the prop since new. Just bought the boat I run with more people so went to a 19 pitch.

Came with my boat a 2026 Yamaha F70. Like new condition no damage, a couple really small insignificant microscopic leading edge nicks.
