( Manufacturer Part Number: 23-89574 ), ( Part Type: Bushing ), ( Country Of Origin: United States )
The **Mercury 23-89574-0750 Boat Quicksilver Bushing 21** is a precision-engineered, high-performance replacement bushing designed specifically for Mercury outboard motors, ensuring optimal functionality and longevity in demanding marine environments. This bushing is part of the **Quicksilver** line, a trusted series known for its durability, corrosion resistance, and seamless integration with Mercury s propulsion systems. Crafted from high-grade, reinforced materials, this bushing is engineered to withstand the constant stress of engine movement, vibration, and exposure to saltwater, freshwater, and varying temperatures making it an ideal choice for both recreational boaters and professional anglers who demand reliability in their equipment.
The **23-89574-0750** is a critical component in the steering and drive train of Mercury outboards, particularly those equipped with the **21-inch propeller shaft assembly**. Its primary function is to reduce friction, absorb shock, and maintain smooth operation between the steering linkage and the engine s internal mechanisms, preventing premature wear on critical parts like the steering rod, brackets, and lower unit. Constructed with a **metal-backed, rubberized insert**, this bushing provides superior load-bearing capacity while dampening noise and vibration, enhancing both comfort and performance during extended hours on the water. Its robust design also helps mitigate the effects of harsh conditions, such as rough seas or prolonged exposure to UV rays, which can degrade standard bushings over time.
Installation of the **Mercury 23-89574-0750** is straightforward, thanks to its standardized dimensions and compatibility with Mercury s outboard models, including those from the **200 to 400 HP series** (depending on specific engine configuration). The bushing features a **press-fit or bolt-on design**, allowing for easy replacement without the need for specialized tools, though proper alignment and torque specifications should be followed to ensure optimal performance. When fitted correctly, it restores the original factory function of the steering system, reducing play in the linkage and improving steering responsiveness an essential factor for maneuverability in tight spaces, such as docks, marinas, or crowded fishing spots.
For boaters who prioritize **long-term reliability and performance**, this bushing is a cost-effective upgrade that extends the lifespan of their Mercury outboard. Its **corrosion-resistant properties** make it particularly well-suited for saltwater applications, where standard bushings may degrade rapidly due to moisture and salt buildup. Additionally, the **Quicksilver brand** is backed by Mercury s reputation for quality, ensuring that each bushing meets stringent manufacturing standards for consistency and performance. Whether used as an original equipment replacement or an aftermarket upgrade, the **23-89574-0750** is a small but vital part that contributes significantly to the overall efficiency and durability of a Mercury-powered vessel.
### **Pros and Cons of buying a Mercury 23-89574-0750 (Quicksilver Bushing 21)**
#### **Pros:**1. **OEM Compatibility** This part is designed as an original equipment manufacturer (OEM) replacement, meaning it should fit perfectly on your Mercury 23 engine without modifications. This reduces the risk of installation issues and ensures proper function.
2. **Durability and Performance** Mercury Marine parts are known for their quality and reliability. The Quicksilver bushing is engineered to withstand the stresses of marine environments, reducing wear on critical components like the propeller shaft and stern drive.
3. **Extended Lifespan** By replacing a worn or damaged bushing, you can prevent premature failure of other parts, such as the stern drive or propeller shaft seals. This helps avoid costly repairs down the line.
4. **Easier Maintenance** Since bushings are subject to wear, replacing them proactively can simplify future maintenance. A well-maintained bushing reduces vibration and noise, improving overall engine performance.
5. **Warranty Coverage** If purchased directly from Mercury or an authorized dealer, this part may come with a warranty, providing peace of mind against defects.
6. **Aftermarket Availability** Even if you can t find it directly from Mercury, many third-party suppliers offer compatible replacements, ensuring availability if needed.

#### **Cons:**1. **Cost** As an OEM part, the Mercury 23-89574-0750 may be more expensive than aftermarket alternatives. While aftermarket parts can be cheaper, they may not always match the durability or fit of an OEM component.
2. **Installation Complexity** Replacing a stern drive bushing requires some mechanical skill. If you re not experienced with marine engine work, you may need to hire a professional, adding labor costs.
3. **Potential Counterfeit Parts** If purchasing from an untrusted seller (especially online), there s a risk of receiving a counterfeit or low-quality replica. Always buy from reputable sources to avoid this issue.
4. **Limited Customization** Since this is a stock part, you won t have options for upgrades or modifications beyond what Mercury offers. If you re looking for performance enhancements, you may need to explore other solutions.
5. **Availability Issues** Depending on your location, this specific part might not always be in stock at local marine supply stores. You may need to order online, which could delay repairs.
6. **Wear and Tear Over Time** Even with a high-quality bushing, marine environments (saltwater, debris, and constant movement) can still cause wear. Regular inspection and maintenance are necessary to extend its lifespan.

### **Conclusion**
The **Mercury 23-89574-0750 Quicksilver Bushing 21** is a reliable OEM replacement that ensures proper fit, durability, and performance for your engine. While it may come at a higher cost than aftermarket alternatives, the long-term benefits such as reduced vibration, extended component life, and fewer repair needs often justify the investment.
If you re comfortable with basic mechanical work or have access to a marine technician, replacing the bushing yourself can save labor costs. However, if you re unsure about installation, hiring a professional is the safer option to avoid potential damage.
For those concerned about cost, comparing prices from authorized dealers and reputable aftermarket suppliers (like **Mercury Marine, Sea-Doo, or trusted marine parts retailers**) can help you find the best balance between quality and affordability.
### **Recommendation**
- **Buy from an authorized dealer or trusted supplier** to ensure authenticity and warranty coverage.
- **Replace the bushing as soon as you notice excessive vibration, noise, or play in the stern drive**, as further damage can be costly.
- **Follow Mercury s maintenance guidelines** to maximize the bushing s lifespan and overall engine health.
- **Consider professional installation** if you lack experience with marine engine repairs to avoid mistakes.
If your budget allows, the **OEM part is the best choice** for reliability, but if you re on a tight budget and the part is in good condition, a high-quality aftermarket alternative (from a reputable brand) could be a cost-effective compromise. Always prioritize quality over price to prevent future engine issues.
