### **Pros and Cons of buying a OMC 0390972 (Johnson/Evinrude 390972 Gear Bearing Kit)**
#### **Pros:**1. **Compatibility** This kit is specifically designed for Johnson/Evinrude outboards with the model number **390972**, ensuring a perfect fit without modification. It replaces worn or damaged gears and bearings, restoring smooth operation.
2. **Performance Restoration** A failing gear or bearing can cause excessive vibration, rough shifting, or even complete transmission failure. Replacing these components prevents further damage to the drive unit and restores optimal power transfer.
3. **Longevity** High-quality gears and bearings reduce wear on other transmission parts, potentially extending the life of the entire drivetrain if installed correctly.
4. **Cost-Effective Repair** Replacing a single failed gear or bearing can be expensive, but a complete kit ensures all critical components are fresh, preventing future failures and avoiding more costly repairs.
5. **Ease of Installation** While some DIYers may find gear/bearing replacement challenging, this kit is designed for straightforward installation with proper tools (e.g., gear puller, bearing press). Many marine mechanics recommend it for its simplicity compared to custom parts.
6. **Warranty Coverage** If purchased from an authorized dealer or reputable supplier, the kit may come with a warranty, providing peace of mind against manufacturing defects.
7. **Prevents Catastrophic Failure** A seized or broken gear can damage the transmission housing or shaft, leading to expensive repairs. Replacing these components proactively avoids such scenarios.
---
#### **Cons:**1. **Skill Dependency** Installing a gear/bearing kit requires mechanical aptitude, especially if the transmission is not regularly serviced. Improper installation (e.g., misaligned gears, incorrect lubrication) can cause premature failure or damage.
2. **Labor Costs** If not installing it yourself, professional labor can be expensive, sometimes costing more than the kit itself. A typical marine mechanic may charge **$200 $500 ** depending on location and complexity.
3. **Tool Requirements** Specialized tools like a gear puller, bearing press, and torque wrench are needed. Renting or purchasing these adds to the overall cost if not already owned.
4. **Potential for Contamination** If the transmission is not cleaned thoroughly before installation, debris can enter the new components, leading to premature wear.
5. **Limited Availability** OMC/Evinrude parts can be harder to find than aftermarket alternatives, especially in remote areas. Ordering online may involve shipping delays.
6. **Risk of Counterfeit Parts** Purchasing from unverified sellers (e.g., third-party marketplaces) could result in substandard or fake parts, voiding warranties and risking performance issues.
7. **Time-Consuming Process** A full gear/bearing replacement can take **4 8 hours** for a skilled mechanic, requiring the boat to be out of commission during repairs.

### **Conclusion**
The **OMC 0390972 Johnson/Evinrude Gear Bearing Kit** is a **highly recommended** solution for restoring or maintaining a failing transmission in compatible outboards. Its **direct compatibility, performance benefits, and preventive maintenance value** make it a worthwhile investment for boat owners who prioritize reliability.
However, the **cost of labor, required skill level, and tool dependency** mean that **DIY installation is ideal** if you have mechanical experience. If not, hiring a **certified marine mechanic** ensures proper fitting and avoids costly mistakes.
For long-term boat owners, **regular transmission maintenance** (including gear/bearing checks) is far cheaper than reactive repairs. This kit is particularly valuable for **high-mileage or frequently used boats** where transmission wear is more likely.
### **Final Recommendation:**- **Buy the kit** if you have the **model number 390972** and need to address gear/bearing failure.
- **Install it yourself** if you have **basic mechanical skills and the right tools** to save on labor.
- **Consult a professional** if unsure about installation to avoid damaging the transmission.
- **Purchase from an authorized dealer** to ensure authenticity and warranty coverage.
This kit is a **smart investment** for preventing transmission failure and extending the life of your outboard engine.
