( Manufacturer Part Number: 806856 ), ( Part Type: Hose )

Review MERCURY Hose Oem New

The **Mercury 806856 Hose** is a high-performance, heavy-duty marine and industrial hose designed to deliver exceptional reliability, durability, and resistance to harsh operating conditions. Engineered for demanding applications such as outboard motor fuel lines, engine cooling systems, and hydraulic setups, this hose combines superior flexibility with robust structural integrity to ensure consistent performance even under extreme pressure and temperature fluctuations. Constructed from a reinforced synthetic rubber compound, the 806856 hose features a multi-layered design that incorporates a braided fiber reinforcement, typically made from aramid or polyester, to withstand bending, kinking, and abrasion while maintaining its shape and reducing the risk of leaks. Its smooth, oil-resistant inner lining prevents fuel or coolant degradation, ensuring longevity and compatibility with a wide range of fluids, including gasoline, diesel, and antifreeze. The outer jacket is often formulated to resist UV degradation, ozone, and environmental contaminants, making it ideal for prolonged exposure to sunlight, saltwater, and corrosive chemicals. Whether installed in a high-performance outboard engine, a marine propulsion system, or an industrial pump application, this hose delivers a seamless connection between components, minimizing vibration-induced wear and reducing the likelihood of catastrophic failure. Mercury s attention to precision engineering ensures a tight, leak-proof fit with standard fittings, while its resistance to cracking and swelling from exposure to fuels or solvents guarantees dependable operation over thousands of hours. Built to meet stringent industry standards, the 806856 hose is a trusted choice for marine enthusiasts, boat manufacturers, and professionals who demand a balance of performance, durability, and ease of installation.

**Pros and Cons of buying a Mercury 806856 Hose**

The Mercury 806856 is a high-pressure, low-volume hose commonly used in marine applications, particularly for fuel transfer, bilge pumping, and other fluid transfer systems. Below is a detailed breakdown of its advantages and disadvantages.

### **Pros**

1. **Durability and Longevity** Constructed with reinforced materials, this hose is designed to withstand harsh marine environments, including exposure to UV rays, saltwater, and abrasive conditions. Its reinforced fabric layers and rubber compound help prevent kinking, cracking, and premature wear.

2. **High Pressure Resistance** The hose is rated for high-pressure applications (typically up to 150 PSI or more, depending on specifications), making it suitable for fuel transfer, bilge pumping, and other demanding fluid transfer tasks. This reduces the risk of leaks or bursts under normal operating conditions.

3. **Chemical and Fuel Compatibility** The rubber compound used in this hose is often resistant to gasoline, diesel, oil, and other common marine fuels. This makes it a reliable choice for fuel lines, reducing the risk of degradation or contamination.

4. **Flexibility and Maneuverability** Despite its reinforced construction, the hose remains flexible enough to navigate tight spaces in marine systems, such as engine bays or bilge compartments. This flexibility also helps reduce strain on fittings and connections.

5. **Easy Installation and Maintenance** The hose is typically pre-fitted with barbed or threaded ends, simplifying installation. It can be cut to length and reconnected without requiring specialized tools, making repairs or replacements straightforward.

6. **Wide Availability and Compatibility** As a widely used marine hose, the 806856 is easy to find in marine supply stores, online retailers, and through Mercury s authorized dealers. It is also compatible with a variety of fittings and connectors, increasing its versatility.

7. **Cost-Effective for Long-Term Use** While the initial cost may be moderate, its durability and resistance to wear mean it often lasts longer than cheaper, lower-quality hoses. This can save money in the long run by reducing the need for frequent replacements.

8. **Brand Reputation** Mercury is a trusted name in marine and power equipment, and their hoses are engineered to meet strict performance standards. This brand reliability can be reassuring for buyers who prioritize quality and dependability.

### **Cons**

1. **Higher Upfront Cost Compared to Generic Hoses** While the Mercury 806856 is durable, it is generally more expensive than generic or aftermarket hoses. For budget-conscious buyers, this may be a significant drawback, especially if only a short length is needed.

2. **Limited Color Options** Most Mercury hoses come in standard colors (typically black or gray), which may not be ideal for customization or color-coding in specific applications. This lack of variety can be inconvenient for users who prefer distinct visual identification.

3. **Potential for Overkill in Low-Pressure Applications** If the hose is used in applications where high pressure is not required (e.g., simple water transfer), its reinforced construction may be unnecessary, leading to wasted investment. In such cases, a lighter-duty hose could suffice.

4. **Weight** Due to its reinforced layers, the hose is heavier than standard rubber hoses. This can make handling and installation more cumbersome, particularly in tight or hard-to-reach areas of a boat.

5. **Specialized Fittings May Be Required** While the hose is compatible with many standard fittings, some applications may require specific adapters or connectors that are not universally available. This could add to the cost or complexity of installation.

6. **Environmental Considerations** The rubber compound used in the hose may not be fully biodegradable or eco-friendly. If sustainability is a priority, alternative hoses made from more environmentally friendly materials might be preferable.

7. **Potential for Mislabeling or Counterfeit Products** As with many branded products, there is a risk of purchasing counterfeit or mislabeled hoses that do not meet Mercury s specifications. Buyers should always verify the product s authenticity, especially when purchasing from third-party sellers.

8. **Limited Customization** Unlike some aftermarket hoses, the Mercury 806856 does not offer custom lengths or specialized features (e.g., braided reinforcement for extra flexibility). Buyers must work with the standard lengths and configurations available.

### **Conclusion and Recommendation**

The **Mercury 806856 hose** is an excellent choice for marine applications that require durability, high-pressure resistance, and chemical compatibility. Its reinforced construction ensures longevity in demanding environments, making it ideal for fuel transfer, bilge pumping, and other critical fluid transfer tasks. The brand s reputation for quality and the hose s ease of installation further add to its appeal.

However, the higher cost and weight may not justify its use in low-pressure or non-critical applications. Buyers should carefully consider their specific needs before purchasing. If budget is a concern and the application does not require high pressure, a generic or aftermarket hose might be a more cost-effective alternative.

- You need a reliable, long-lasting hose for high-pressure marine applications (e.g., fuel transfer, bilge pumping).

- You prioritize brand quality and durability over cost savings.

- You require a hose that can withstand harsh conditions without frequent replacements.

- Your application involves low-pressure fluid transfer where a lighter-duty hose would suffice.

- You are working on a tight budget and can find a similarly rated generic hose at a lower price.

- You need custom lengths or specialized features not offered by the Mercury 806856.

For most serious marine users, the Mercury 806856 hose is a **strong, well-supported choice** that delivers on performance and reliability. Always verify the product s authenticity and ensure it meets your specific pressure and chemical compatibility requirements.
