Review QUICKSILVER Blade.s. Boat Prop 3/4 20p Spline Rh fits 2012–2013

The **Quicksilver 48-46772 Blade S.S. Boat Propeller** is a high-performance, stainless steel marine propeller meticulously engineered for maximum efficiency, durability, and reliability in demanding boating applications. Designed with a **12 3/4-inch diameter** and a **20-pitch** configuration, this propeller strikes an ideal balance between speed and torque, making it an excellent choice for mid-sized powerboats, fishing vessels, and performance cruisers. The **13-spline shaft connection** ensures a secure, vibration-dampening fit, reducing wear on both the propeller and the transmission while enhancing overall propulsion performance. Crafted from **marine-grade stainless steel (316)**, this propeller is built to withstand the harshest conditions, including saltwater corrosion, abrasive debris, and high-speed operation, delivering long-lasting performance with minimal maintenance. The **S.S. (Stainless Steel) blade design** features optimized hydrodynamics, with carefully contoured surfaces that minimize drag and maximize thrust efficiency, allowing for smoother acceleration, better fuel economy, and reduced strain on the engine. Whether used in a recreational setting, for serious anglers seeking precision control, or in commercial applications where reliability is critical, this propeller s robust construction and precision engineering ensure consistent, high-performance propulsion. Ideal for boats ranging from 20 to 35 feet, the **48-46772** is a versatile upgrade for those seeking a blend of speed, durability, and quiet operation, making it a standout choice for discerning boat owners who demand nothing less than excellence.

### **Pros and Cons of buying a QuickSilver 48-46772 Blade S.S. Boat Prop (12 3/4" x 20P, 13 Spline RH)**

#### **Pros:**

1. **High Performance for Fishing Boats** The 48 blade angle is optimized for planing and cruising speeds, making it ideal for fishing boats that require a balance between speed and efficiency. It provides a good lift-to-drag ratio, which helps maintain speed while reducing fuel consumption.

2. **Stainless Steel Construction** The blade is made from stainless steel, which offers durability and resistance to corrosion from saltwater, freshwater, and general wear. This extends the prop s lifespan compared to aluminum or bronze alternatives.

3. **Standard 13-Spline Shaft Fit** The 13-spline shaft connection is common in many outboard and sterndrive applications, making it easy to install without needing custom adapters. This ensures compatibility with a wide range of engines.

4. **Right-Hand Rotation (RH) Design** The RH threading is standard for most outboards and sterndrives, reducing the need for special fittings or modifications during installation.

5. **Good for Moderate Loads** The 20-pitch (20P) design is suitable for boats that operate at moderate speeds (typically 15 25 mph) and handle moderate loads, such as fishing boats, cruisers, or small utility vessels. It provides a smooth ride without excessive vibration.

6. **Affordable Compared to High-End Props** While not the cheapest option, it offers a balance between cost and performance, making it a practical choice for budget-conscious boat owners who still want a durable stainless steel prop.

7. **Easy to Find Replacements** QuickSilver is a well-known brand with widespread availability, so finding replacement blades or repairs is relatively straightforward.

#### **Cons:**

1. **Not Ideal for High-Speed or Heavy Loads** The 48 blade angle and 20-pitch design are not optimized for high-speed planing (above 30 mph) or heavily loaded boats (e.g., large bowriders or high-performance racing boats). In such cases, a more aggressive pitch (e.g., 24P or 28P) or a different blade angle (e.g., 50 54 ) would be better.

2. **Limited Customization** Unlike some high-end props, this model does not offer adjustable pitch or custom blade designs. If your boat s performance requires fine-tuning, you may need to consider a different prop.

3. **Potential for Cavitation at High RPMs** Stainless steel props can be prone to cavitation (pitting) if the engine runs at very high RPMs for extended periods. While this prop is durable, excessive cavitation can reduce efficiency over time.

4. **Weight Consideration** Stainless steel props are heavier than aluminum or bronze alternatives. This can slightly reduce acceleration and maneuverability, though the difference is usually negligible for most recreational boats.

5. **Installation May Require Professional Help** If you re not experienced with prop installation, removing the old prop and securing the new one properly (especially with the 13-spline connection) may require professional assistance to avoid damage or misalignment.

6. **Not Suitable for Deep-V or Extreme Planing Boats** Deep-V hulls or boats designed for extreme planing often benefit from props with more aggressive pitches (e.g., 24P 32P) and different blade angles (e.g., 50 54 ). This prop may not deliver optimal performance in those applications.

7. **Potential for Vibration at Certain Speeds** Some users report minor vibration at specific speeds, which can be mitigated by adjusting the trim angle or using a vibration-dampening system. However, this is not unique to this prop and can occur with any propeller.

### **Conclusion:**

The QuickSilver 48-46772 blade stainless steel prop is a solid, mid-range choice for boats that operate at moderate speeds (15 25 mph) and handle moderate loads, such as fishing boats, cruisers, or small utility vessels. Its stainless steel construction ensures durability and corrosion resistance, while the 20-pitch and 48 blade angle provide a good balance of efficiency and performance. However, it is not ideal for high-speed planing, heavy loads, or boats requiring aggressive pitch designs.

If your boat falls into the typical recreational or fishing category and you prioritize reliability and ease of use, this prop is a practical and cost-effective option. For boats that demand higher performance (e.g., deep-V hulls, high-speed planing, or heavy loads), a more specialized prop (e.g., a higher pitch or different blade angle) would be preferable.

---

### **Recommendation:** - **Buy this prop if:**

- You have a fishing boat, cruiser, or small utility vessel operating at moderate speeds (15 25 mph).

- You want a durable, corrosion-resistant stainless steel prop without excessive cost.

- Your engine and boat setup are compatible with a 13-spline, 20-pitch, RH prop.

- You prioritize simplicity and ease of installation over extreme performance.

- **Consider alternatives if:**

- Your boat is a deep-V hull or designed for high-speed planing (look for props with 24P 32P and 50 54 blades).

- You frequently operate at very high RPMs or with heavy loads (a more aggressive pitch may be needed).

- You want adjustable or custom props for fine-tuning performance.

- Your budget allows for a higher-end prop with better cavitation resistance (e.g., some bronze or custom stainless steel options).

For most average boat owners in the target use case, this prop offers a good balance of quality and value. Always ensure it matches your engine s RPM range and your boat s intended use for optimal results.
