### **Pros and Cons of buying a GHMarine 63V-85520-00 Charge Coil for Yamaha 2-Stroke Outboards (9.9HP/15HP, 1996-2009)**
#### **Pros:**1. **Direct Compatibility** The GHMarine coil is specifically designed as an OEM replacement for Yamaha 2-stroke outboards from 1996 to 2009, including the 9.9HP and 15HP models. This ensures a proper fit without modification, reducing the risk of installation errors.
2. **Improved Ignition Performance** A high-quality charge coil can enhance spark consistency, leading to smoother engine operation, better fuel efficiency, and reduced misfires especially important in older 2-stroke engines prone to ignition issues.
3. **Durability and Longevity** GHMarine coils are built with robust materials, often featuring corrosion-resistant coatings and reinforced wiring. This can extend the coil s lifespan compared to generic or low-quality aftermarket parts, which may degrade faster in marine environments.
4. **Easier Installation** Since it s a direct replacement, swapping the old coil for the GHMarine unit typically requires minimal effort just disconnecting wires and bolts. No wiring harness modifications or additional tools are usually needed.
5. **Warranty and Support** GHMarine offers warranties on their products, providing peace of mind in case of defects. Their customer service is often responsive, which can be helpful if issues arise post-installation.
6. **Cost-Effective Upgrade** Compared to full engine rebuilds or replacements, a coil upgrade is a low-cost solution to restore or improve performance. It s a simple fix that can prevent more expensive problems down the line.
7. **Compatibility with Aftermarket Tuning** If you ve modified your engine (e.g., with a performance air filter, carburetor tweaks, or a performance exhaust), a high-quality coil can better support the increased airflow and power output, reducing the risk of ignition-related failures.

#### **Cons:**1. **Price Premium** While still affordable compared to engine repairs, the GHMarine coil may cost more than generic or no-name brands. If budget is a concern, cheaper alternatives exist, though with potential trade-offs in quality and reliability.
2. **Potential Overkill for Mild Use** If your boat is used infrequently or in calm waters, the benefits of an upgraded coil may be minimal. In such cases, the original OEM coil (if still functional) might suffice, making the upgrade unnecessary.
3. **Installation Risks (If DIY)** While straightforward, improper handling during installation (e.g., bent terminals, loose connections, or incorrect torque) can lead to electrical issues or premature failure. Those unfamiliar with electrical work may need to consult a professional.
4. **Environmental Factors** Marine environments expose coils to saltwater, humidity, and vibration. Even a high-quality coil can degrade faster if not properly sealed or if water ingress occurs (e.g., due to a faulty cowling or gasket). Regular maintenance is essential.
5. **Mixed Reviews on Longevity** Some users report that while the GHMarine coil improves performance, it may not last as long as Yamaha s original parts in extreme conditions. Others find it significantly more durable. Expectations vary based on usage and maintenance.
6. **Limited Availability of Parts** If the coil fails again, sourcing a replacement may be easier with GHMarine than with some lesser-known brands, but availability can still be an issue depending on the region.
7. **No Guarantee of Fixing All Issues** If your engine has deeper problems (e.g., worn pistons, carburetor fouling, or fuel system issues), replacing just the coil won t resolve them. A coil upgrade is a symptom fix, not a root-cause solution.

### **Conclusion:**The **GHMarine 63V-85520-00 charge coil** is a **strong, reliable choice** for Yamaha 2-stroke outboards (9.9HP/15HP, 1996 2009) when seeking an OEM-quality replacement or an upgrade. It addresses common ignition-related issues in older engines, offering improved performance, durability, and ease of installation. The pros outweigh the cons for most users, especially those who prioritize longevity and compatibility.
However, if your boat is rarely used or you re on a tight budget, the original coil (if still functional) or a budget-friendly alternative might be sufficient. For heavy-duty or performance-oriented use, the GHMarine coil is a **recommended investment** to prevent misfires, improve throttle response, and extend the engine s life.
### **Final Recommendation:** **Buy the GHMarine coil if:**- Your engine is experiencing misfires, rough idling, or poor starting.
- You want a direct OEM replacement with better durability than generic brands.
- You plan to use the boat frequently or in demanding conditions.
- You re willing to pay a slightly higher price for long-term reliability.
**Avoid or reconsider if:**- Your engine has other underlying issues (e.g., carburetor problems, fuel system leaks).
- You re using the boat sporadically in calm waters with minimal power demands.
- You re unwilling to perform basic installation checks or seek professional help if needed.
**Additional Tips:**- Inspect the coil s terminals and wiring for corrosion before installation.
- Consider applying dielectric grease to terminals to prevent future corrosion.
- Pair the coil upgrade with regular maintenance (e.g., fuel system cleaning, spark plug checks).
- If possible, test the coil with a multimeter to ensure proper resistance before installation.
