Review EAST OUTBOARD MARINE Yanmar Sea Water Pump Replaces 6lp

The **East Outboard Marine Yanmar Sea Water Pump Kit (Part Numbers: 119773-42650, 119773-42651, 119773-42652, 6LP, 6LPA)** is a precision-engineered, high-performance cooling system component designed exclusively for Yanmar outboard marine engines, ensuring optimal thermal management and long-term reliability in demanding marine environments. This meticulously crafted assembly features a robust **6LP or 6LPA impeller configuration**, tailored to deliver superior water flow efficiency while minimizing strain on the engine s cooling system. The **119773-42650** pump housing, forged from durable marine-grade materials, provides a tight seal against corrosion and abrasion, safeguarding against the harsh effects of saltwater exposure over extended periods. Complementing this is the **119773-42651 impeller**, engineered with precision-cut blades optimized for maximum water displacement and reduced cavitation, ensuring consistent cooling performance even under high-load conditions. The **119773-42652 gasket and seal kit** included in this package guarantees a leak-proof installation, preventing water ingress into critical engine components and maintaining operational integrity. Whether installed in a high-performance recreational vessel, a commercial fishing boat, or a workboat, this pump kit is built to withstand the rigors of saltwater corrosion, thermal cycling, and continuous operation, making it an indispensable upgrade for marine engines seeking enhanced durability and cooling efficiency. Its compatibility with Yanmar s 6LP and 6LPA engine models ensures seamless integration, while its modular design allows for quick and straightforward replacement, minimizing downtime during maintenance. Trusted by marine professionals for its reliability and performance, this pump kit is the ideal solution for preserving engine health and extending the lifespan of Yanmar-powered outboards in the most demanding aquatic environments.

### **Pros and Cons of buying a Eastin Outboard Marine Sea Water Pump (Yanmar 119773-42651, 119773-42650, 119773-42652, 6LP/6LPA)**

#### **Pros:**

1. **Compatibility with Yanmar Engines** These pumps are specifically designed for Yanmar marine outboard engines (6LP and 6LPA series), ensuring proper fitment and performance. Using an OEM or high-quality aftermarket part reduces the risk of compatibility issues.

2. **Reliability and Durability** Yanmar engines are known for their robustness, and their associated components, including sea water pumps, are built to withstand marine conditions. A genuine or well-matched replacement pump should provide long-term service without frequent failures.

3. **Prevents Engine Overheating** The sea water pump circulates cooling water through the engine s jacket, preventing overheating and potential damage. A failing pump can lead to catastrophic engine failure, so replacing it proactively is critical.

4. **Ease of Installation** These pumps are straightforward to replace, especially if you have basic mechanical skills. Most require only a few tools (socket wrench, gasket scraper, and sealant) and can be done in under an hour with the engine removed from the water.

5. **Cost-Effective Alternative to Engine Replacement** Fixing a seized or overheated Yanmar engine due to a failed sea water pump can cost thousands of dollars. Replacing the pump is a fraction of that cost, making it a wise preventive measure.

6. **Aftermarket Options Available** While Eastin is a reputable brand, other high-quality manufacturers (such as Seafoam, Marine Parts One, or direct Yanmar replacements) offer similar pumps at competitive prices. This gives buyers flexibility in sourcing.

7. **Warranty Coverage** If purchasing from a dealer or authorized seller, some pumps may come with a warranty (e.g., 1 2 years), providing peace of mind against early failure.

8. **Improved Fuel Efficiency** A properly functioning cooling system ensures the engine operates at optimal temperatures, which can slightly improve fuel efficiency and performance.

---

#### **Cons:**

1. **Limited Availability Outside Specialty Stores** These pumps may not be stocked at local marine supply chains or big-box stores. Buyers often need to order online from specialty marine parts dealers, which can extend wait times.

2. **Potential for Counterfeit Parts** If purchasing from untrusted sellers (e.g., eBay, Amazon, or unknown marketplaces), there is a risk of receiving counterfeit or low-quality replicas. Always verify the seller s reputation and product authenticity.

3. **Replacement Cost** While cheaper than engine repairs, the pump itself is not extremely inexpensive. Prices typically range from **$100 $200** depending on the model and seller. For older boats or high-hour engines, this may still be a significant expense.

4. **Maintenance Requirements** Sea water pumps are exposed to corrosive saltwater, so they may require periodic inspection. Impeller wear, shaft corrosion, or seal leaks can occur over time, necessitating eventual replacement.

5. **Installation Challenges for DIYers** While the process is manageable, improper sealing or torque can lead to leaks. Those without mechanical experience may struggle with alignment or gasket application, potentially damaging the engine or water intake.

6. **Environmental Impact of Saltwater Use** Sea water pumps are designed for saltwater use, but prolonged exposure to freshwater (e.g., in lakes or after washing the boat) can accelerate corrosion. Regular flushing with freshwater after saltwater use is recommended.

7. **Limited Lifespan Compared to Freshwater Pumps** Sea water pumps typically last **500 1,000 hours** before requiring replacement, whereas freshwater pumps can last much longer. This means owners of high-use boats may need to replace them more frequently.

8. **Potential for Impeller Clogging** Debris in the water intake (e.g., marine growth, trash) can clog the impeller, reducing efficiency. Regular cleaning of the strainer and intake screen is necessary to prevent this.

### **Conclusion**

The Eastin (or compatible) Yanmar sea water pump is a **critical and cost-effective component** for maintaining the health of a Yanmar 6LP/6LPA outboard engine. The **pros far outweigh the cons** for most boat owners, as the risks of engine failure due to overheating are severe and expensive to repair. The pump s **reliability, compatibility, and ease of replacement** make it a smart investment for preventive maintenance.

However, buyers should **prioritize quality and authenticity** to avoid counterfeit parts and ensure long-term performance. Purchasing from **authorized dealers, marine specialty stores, or reputable online sellers** (with verified reviews) minimizes risks. Additionally, **regular maintenance** (e.g., inspecting for leaks, cleaning the intake, and flushing with freshwater) will extend the pump s lifespan.

For those who frequently use their boats in saltwater, **budgeting for pump replacement every 500 1,000 hours** is advisable. If the boat is used less frequently, the pump may last longer, but it should still be inspected annually.

### **Recommendation**

- **Buy from a trusted source** (e.g., Eastin s official website, Marine Parts One, or a local marine dealer) to ensure authenticity.

- **Compare prices** between Eastin and other high-quality brands (e.g., Yanmar OEM, Seafoam) to find the best value.

- **Replace the pump proactively** if it s nearing its expected lifespan, rather than waiting for failure.

- **Follow installation guidelines carefully**, using the correct gasket and sealant to prevent leaks.

- **Monitor the engine s temperature** post-installation to confirm the pump is functioning correctly.

**Final Verdict:** This is a **necessary and worthwhile purchase** for Yanmar 6LP/6LPA outboard owners, provided it is sourced responsibly and maintained properly. Skipping this replacement could lead to far more costly engine damage.
