### **Pros and Cons of buying a Sierra 18-99398 OMC Trigger Sensor (CD2)**

1. **Compatibility with OMC Engines** This sensor is specifically designed for OMC (Outboard Marine Corporation) engines, ensuring proper functionality and reliability with minimal risk of compatibility issues.

2. **High-Quality Construction** Built with durable materials, it is designed to withstand harsh marine environments, including exposure to water, salt, and vibration.

3. **Easy Installation** The sensor is designed for straightforward installation, often requiring minimal tools and minimal downtime for replacement.

4. **Reliability for Performance** A faulty trigger sensor can cause engine misfires, rough idling, or failure to start. Replacing it with an OEM or high-quality aftermarket part like this ensures smoother operation.

5. **Cost-Effective Alternative** While not the cheapest option, it is often more affordable than some OEM replacements, offering a balance between quality and price.

6. **Widely Available** As an older but still common part, it can be found at marine supply stores, online retailers, and through boat dealerships.

7. **Direct Replacement** The CD2 designation suggests it is a direct-fit replacement for the original sensor, reducing the need for modifications or additional parts.

1. **Age of the Part** The Sierra 18-99398 model is not a brand-new design, which means it may lack some of the latest advancements in sensor technology, such as improved durability or diagnostic capabilities.

2. **Potential Availability Issues** While still available, parts for older OMC engines may become harder to source over time, especially if the engine model is discontinued.

3. **Mixed Quality Perception** Some users report inconsistent quality in aftermarket parts, though this can vary by supplier. Always check reviews or purchase from reputable sellers.

4. **Limited Warranty** Unlike some OEM parts, aftermarket sensors may come with shorter or no warranties, leaving you responsible for any premature failures.

5. **Compatibility with Modified Engines** If the engine has been heavily modified or upgraded, the sensor may not integrate perfectly, requiring additional adjustments.

6. **Potential for Counterfeit Parts** Buying from untrusted sellers increases the risk of receiving a fake or low-quality replica, which could perform poorly or fail quickly.

The Sierra 18-99398 OMC Trigger Sensor (CD2) is a solid choice for those needing a reliable, direct-fit replacement for OMC engines, particularly older models. It offers good compatibility, durability, and ease of installation, making it a practical solution for addressing engine performance issues. However, its age and potential availability concerns mean it may not be the best long-term investment for newer or heavily modified engines. Additionally, purchasing from a trusted supplier is crucial to avoid counterfeit or low-quality parts.

If you are replacing a faulty trigger sensor in an older OMC engine and need a cost-effective, direct-fit solution, the Sierra 18-99398 CD2 is a reasonable option. Prioritize buying from a reputable dealer or supplier with good reviews to ensure authenticity and quality. If your engine is newer or you plan to keep it for an extended period, consider whether an OEM or more advanced aftermarket sensor might offer better long-term reliability. Always verify compatibility with your specific engine model before purchasing.
