**Pros and Cons of buying a East Marine Parts 85098A2 Water Pump Impeller Kit for Mercury Outboards (9.9 25 HP)**

### **Pros**

1. **Compatibility and Fitment**

The kit is specifically designed for Mercury outboards ranging from 9.9 to 25 HP, including models like the 9.9, 13.5, 15, 18, 20, and 25 HP engines. This ensures a precise fit without the need for modifications, reducing installation complications.

2. **Quality and Durability**

East Marine is a well-known brand in the marine industry, known for producing reliable and high-quality replacement parts. The impeller kit is likely made from durable materials such as corrosion-resistant plastics or composites, which can withstand the harsh marine environment.

3. **Preventative Maintenance**

A water pump impeller is a critical component for cooling the engine. Over time, wear and tear can lead to reduced efficiency or failure, potentially causing engine overheating or damage. Replacing the impeller as part of routine maintenance can prevent costly repairs down the line.

4. **Ease of Installation**

Since the kit includes the impeller (and possibly a gasket or seal), it is designed for straightforward replacement. Many users report that the process is manageable with basic tools, especially if they have prior experience with outboard maintenance.

5. **Cost-Effective Solution**

Compared to the potential cost of engine damage from a failing water pump, purchasing a replacement impeller kit is a relatively inexpensive preventative measure. It extends the lifespan of the water pump and reduces the likelihood of more extensive repairs.

6. **Warranty and Support**

East Marine products often come with warranties or return policies, providing peace of mind in case of defects or installation issues. Customer support is also typically available for guidance.

### **Cons**

1. **Limited Longevity**

While the impeller itself may last for several years, the water pump housing and seals may still degrade over time. Replacing just the impeller without addressing the entire pump could lead to recurring issues if the pump is worn out.

2. **Potential for Misalignment or Damage**

If the impeller is not installed correctly such as being misaligned or damaged during removal it could cause vibrations, reduced performance, or even damage to the water pump or engine. Careful installation is required to avoid these issues.

3. **Accessibility Challenges**

Depending on the outboard model, accessing the water pump impeller may require removing the lower unit or other components, which can be time-consuming or difficult for inexperienced DIYers. Some users may need to consult a manual or seek professional help.

4. **Quality Variability**

While East Marine is generally reliable, the quality of aftermarket parts can sometimes vary. In rare cases, the impeller may not meet the same standards as OEM (Original Equipment Manufacturer) parts, potentially leading to premature wear or failure.

5. **Environmental Factors**

Exposure to saltwater, freshwater, and UV rays can accelerate wear on the impeller, even if it is made from corrosion-resistant materials. Regular cleaning and maintenance are necessary to prolong its lifespan.

6. **Cost of Additional Components**

If the water pump housing or seals are also worn, replacing just the impeller may not fully resolve the issue. In such cases, additional parts may be required, increasing the overall cost of maintenance.

### **Conclusion**

The East Marine Parts 85098A2 water pump impeller kit is a practical and cost-effective choice for Mercury outboard owners looking to maintain or replace a worn impeller. Its compatibility with a wide range of engines, ease of installation, and reputation for quality make it a strong option for routine maintenance. However, it is essential to address the entire water pump system if other components are degraded, and careful installation is critical to avoid complications.

For most DIYers with basic mechanical skills, this kit is a straightforward and reliable upgrade. Those who are unsure about installation or suspect broader pump issues may benefit from consulting a marine mechanic to ensure a complete and effective solution.

### **Recommendation**

If you are experiencing symptoms such as reduced engine cooling, unusual noises from the water pump, or overheating, replacing the impeller with this kit is a wise preventative step. Ensure you follow the manufacturer s installation guidelines and inspect the water pump housing and seals for signs of wear. For long-term reliability, consider replacing the entire water pump if it is past its service life. If you are not comfortable with the installation process, consult a professional to avoid potential damage. Overall, this kit is a solid choice for maintaining the health of your Mercury outboard.
