The **Yamaha SCD3R17SYM90 Power YBS Propeller** is a high-performance, precision-engineered propeller designed specifically for Yamaha s outboard motors, offering an optimal balance of efficiency, durability, and thrust for both recreational and competitive boating applications. This **13-inch diameter, 17-inch pitch, RH (right-hand) 15-spline K2** propeller is crafted from Yamaha s proprietary **YBS (Yamaha Blade System)** technology, which integrates advanced materials and aerodynamic blade profiles to maximize hydrodynamic performance. The **K2 series** features a refined blade design with optimized camber and twist, reducing cavitation and improving fuel efficiency while delivering exceptional acceleration and top-end speed. The **15-spline shaft** ensures a secure and vibration-dampening connection to the motor s output shaft, minimizing wear and enhancing reliability over extended use. Ideal for mid-sized Yamaha outboards ranging from **150 to 250 horsepower**, this propeller excels in applications such as wakeboarding, waterskiing, and high-speed cruising, where smooth power delivery and responsive handling are critical. Its **symmetrical blade design** enhances maneuverability, making it well-suited for tight turns and precise control, while the **high-strength aluminum construction** ensures resistance to corrosion and fatigue, even in saltwater environments. Whether used on a sportfishing boat, a speedboat, or a versatile wakeboard rig, the **SCD3R17SYM90** delivers a seamless blend of power, efficiency, and longevity, embodying Yamaha s commitment to innovation in marine propulsion.
### **Pros and Cons of buying a Yamaha SCD3R17SYM90 Power Prop/Propeller (13" x 17" RH, 15 Spline, K2)**
#### **Pros:**1. **High Performance and Efficiency** The K2 propeller is designed for high-speed and fuel-efficient operation, making it ideal for cruising and long-distance travel. The 13" x 17" pitch is optimized for Yamaha s 3.0L and 4.2L engines, delivering strong thrust while maintaining smooth operation.
2. **Durability and Reliability** Yamaha propellers are known for their high-quality materials and precision engineering. The K2 series features a robust blade design that resists corrosion and wear, ensuring longevity even in saltwater environments.
3. **Compatibility with Yamaha Outboards** This propeller is specifically engineered for Yamaha s SCD3R (and similar) models, meaning it is factory-tuned for optimal performance with minimal tuning required. It fits seamlessly with the engine s power delivery.
4. **Fuel Efficiency** The aerodynamic blade design reduces drag, improving fuel economy compared to older or generic propellers. This is particularly beneficial for extended trips where fuel costs matter.
5. **Reduced Vibration and Smooth Operation** The balanced construction of the K2 propeller minimizes vibration, enhancing comfort for passengers and reducing wear on the engine and transmission over time.
6. **Easy Installation and Maintenance** Yamaha propellers are designed for straightforward installation, often requiring only basic tools. They also feature a simple cleaning and inspection process, making maintenance manageable.
7. **Resale Value and Brand Trust** Yamaha is a well-respected brand in the marine industry, and OEM propellers retain higher resale value compared to aftermarket alternatives. This can be advantageous if you plan to upgrade or sell your boat later.
8. **Warranty Coverage** Purchasing an OEM Yamaha propeller may come with warranty protection, offering peace of mind against defects or premature failure.

#### **Cons:**1. **Higher Upfront Cost** Compared to aftermarket propellers, Yamaha s OEM propellers are more expensive. While they offer superior quality, the initial investment can be a drawback for budget-conscious buyers.
2. **Limited Customization** Unlike aftermarket propellers, which offer a wide range of pitch, diameter, and material options, the SCD3R17SYM90 is a fixed design. If you later decide to modify your boat s performance (e.g., for towing or high-speed cruising), you may need to replace it.
3. **Potential for Damage in Rough Conditions** While durable, propellers can still suffer damage from striking debris, rocks, or other underwater obstacles. The K2 series is robust, but severe impacts can still warp or crack the blades, requiring replacement.
4. **Saltwater Corrosion Risk** Even with high-quality materials, prolonged exposure to saltwater can accelerate corrosion over time. Regular cleaning and maintenance are necessary to prevent pitting or blade degradation.
5. **Not Ideal for Heavy Towing or Extreme Loads** This propeller is optimized for cruising and recreational use. If you frequently tow heavy loads (e.g., large trailers or water sports equipment), a different propeller (e.g., a larger pitch or heavy-duty model) may be more suitable.
6. **Limited Availability of Replacement Parts** If the propeller fails, finding exact replacements may be easier with OEM parts, but aftermarket options might not match performance. However, Yamaha s reputation ensures reliable sourcing.
7. **Weight Consideration** The propeller, while durable, adds to the overall weight of the drive unit. This may slightly affect handling, especially in smaller boats where weight distribution is critical.

### **Conclusion:**The **Yamaha SCD3R17SYM90 Power Propeller (13" x 17" RH, 15 Spline, K2)** is an excellent choice for owners of compatible Yamaha outboards seeking a balance of performance, durability, and reliability. Its OEM status ensures compatibility, efficiency, and long-term dependability, making it a strong investment for cruising and everyday use. However, the higher cost and limited customization may not appeal to those looking for budget-friendly or highly specialized alternatives.
For most Yamaha SCD3R owners, this propeller is the **best option** due to its optimized design, ease of use, and brand-backed quality. If you prioritize performance, fuel efficiency, and low maintenance, it is highly recommended. However, if you plan to modify your boat s performance significantly (e.g., for racing or heavy towing), exploring alternative propellers may be worth considering.
### **Final Recommendation:** **Buy the Yamaha SCD3R17SYM90 Power Propeller if:**- You own a Yamaha SCD3R or compatible outboard.
- You prioritize fuel efficiency, smooth operation, and long-term reliability.
- You want an OEM part with warranty support.
- You don t plan to drastically alter your boat s performance profile.
**Consider alternatives if:**- You need a propeller for heavy towing or extreme conditions.
- You want more customization options (e.g., different pitches or materials).
- You are operating in extremely harsh environments where corrosion is a major concern (in which case, a stainless steel or nickel-aluminum-bronze propeller might be preferable).
For the average Yamaha SCD3R owner, this propeller is the **ideal choice** for optimal performance and peace of mind.
