### **Pros and Cons of buying a Johnson 0390726 (1986-1987 Evinrude 110HP Outboard Battery Cable)**

1. **Direct Compatibility** This cable is specifically designed for the 1986-1987 Evinrude 110HP outboard, ensuring a proper fit without modifications. This reduces the risk of electrical issues caused by improper wiring.

2. **Reliability** Johnson/Evinrude outboards are known for durability, and using an OEM (Original Equipment Manufacturer) cable helps maintain the system s intended performance. A well-matched cable reduces the chance of voltage drops or intermittent connections.

3. **Ease of Installation** Since it is a direct replacement, installation is straightforward for someone with basic mechanical or electrical knowledge. No additional adapters or complex wiring are required.

4. **Prevents Future Issues** Using the correct cable helps avoid common problems like corrosion, loose connections, or overheating, which can lead to starter motor failure or battery drain.

5. **Cost-Effective for Long-Term Use** While the upfront cost may be higher than a generic cable, investing in a quality part extends the life of your outboard s electrical system, saving money on repairs down the line.

6. **Availability of Parts** Johnson/Evinrude parts remain widely available through marine dealers, online retailers, and salvage yards, making replacements easier if needed.

---

1. **Age of the Part** The 1986-1987 model year is relatively old, meaning the cable may not be as widely stocked as newer parts. This could lead to longer wait times for replacement if the original is damaged.

2. **Potential for Wear** If the original cable was already degraded (e.g., corroded, frayed, or cracked), replacing it with a new one may not fully resolve underlying issues like a failing battery or starter. A thorough inspection of the entire electrical system is recommended.

3. **Price Consideration** Compared to aftermarket or generic cables, an OEM part may be more expensive. However, this is often justified by its reliability and compatibility.

4. **Limited Customization** Unlike aftermarket options, this cable does not offer additional features (e.g., thicker gauge for higher current draw or marine-grade corrosion resistance). If you re upgrading to a more powerful system, a generic cable might be more flexible.

5. **Risk of Counterfeit Parts** Purchasing from untrusted sellers (especially online) could result in a fake or low-quality replica. Always buy from reputable dealers or verified suppliers.

6. **Disassembly Required** Replacing the cable may require removing the outboard from the boat, which can be time-consuming and labor-intensive, especially for older models with less modern mounting systems.

The **Johnson 0390726 battery cable** is a **strong choice** for restoring or maintaining the electrical integrity of a 1986-1987 Evinrude 110HP outboard. Its **direct compatibility, reliability, and ease of installation** outweigh the minor drawbacks, particularly for someone who values **long-term performance and safety**. The main concerns **availability and age-related risks** can be mitigated by purchasing from a trusted source and inspecting the rest of the electrical system (battery, starter, wiring) during replacement.

If the cable is part of a **larger electrical overhaul** (e.g., replacing a corroded battery or starter), it s worth investing in the OEM part to ensure everything functions as intended. For budget-conscious buyers, a **high-quality aftermarket cable** (from brands like **Husky, Mercury, or MarineStart**) could be a viable alternative, provided it meets the same gauge and connection specifications.

---
