**Pros and Cons of Buying a Johnson 63718 Motor Pinion**

The Johnson 63718 motor pinion is a critical component used in various applications, including marine propulsion systems, particularly in outboard motors. Below is a detailed analysis of its advantages and disadvantages.

### **Pros**

1. **Compatibility and Fitment**

The Johnson 63718 pinion is designed specifically for certain models of Johnson outboard motors, ensuring a precise fit. This reduces the risk of misalignment or mechanical failure, which can be costly to repair. It is widely used in older models like the Evinrude Johnson 90 HP, 115 HP, and 150 HP series, making it a reliable replacement part.

2. **Durability and Performance**

Johnson motors are known for their robust construction, and the pinion gear is no exception. When properly maintained, this component can last for thousands of hours, providing consistent performance in both freshwater and saltwater environments. The hardened steel construction helps resist wear, extending the lifespan of the motor.

3. **Ease of Replacement**

Replacing a pinion gear is a relatively straightforward process for mechanics with basic tools. Johnson motors often have accessible pinion shafts, making it easier to remove the old part and install the new one without major disassembly. This can save time and labor costs compared to more complex repairs.

4. **Availability of Parts and Support**

Johnson outboards remain popular, and their parts are still widely available through marine dealerships, online retailers, and specialty suppliers. Additionally, Johnson s legacy in the industry means that mechanics and DIY enthusiasts often have experience working with these components, ensuring smoother repairs.

5. **Cost-Effectiveness Compared to New Motors**

Replacing a pinion gear is significantly cheaper than purchasing a new outboard motor. For older models where parts are no longer manufactured, this can be the only viable option to restore functionality. The cost of a pinion gear is a fraction of the price of a complete motor replacement.

6. **Compatibility with Aftermarket Upgrades**

Some marine enthusiasts modify their outboards for better performance. The Johnson 63718 pinion can often be paired with upgraded propellers or other components to enhance speed and efficiency, making it a flexible choice for customization.

### **Cons**

1. **Age and Obsolescence**

The Johnson 63718 pinion is designed for older outboard models, some of which are no longer in production. This means that finding exact replacements may become difficult over time, especially if the motor is very old. Some suppliers may discontinue stock for discontinued models.

2. **Potential for Wear and Tear**

Like all mechanical parts, pinion gears degrade over time due to friction, corrosion, or improper maintenance. If the motor has been neglected, the pinion may already be worn, leading to poor performance or failure shortly after replacement. A thorough inspection of the entire gear system is recommended before purchasing.

3. **Skill and Tool Requirements**

While the replacement process is manageable, it requires some mechanical skill and the right tools. Misalignment or improper installation can cause premature wear or damage to the motor. Those without experience may need to consult a professional, adding to the cost.

4. **Compatibility Issues with Modified Motors**

If the original motor has been heavily modified (e.g., with aftermarket shafts, gears, or propellers), the Johnson 63718 pinion may not fit perfectly. This could lead to compatibility issues, requiring additional adjustments or the need for a different part entirely.

5. **Limited Warranty or Guarantee**

Since the Johnson 63718 pinion is a used-market or replacement part, it may not come with a manufacturer s warranty. Purchasing from a reputable supplier can mitigate this risk, but buyers should be prepared for potential long-term reliability concerns.

6. **Environmental Factors**

Saltwater exposure accelerates corrosion and wear on metal components. If the motor has been used in saltwater without proper maintenance, the pinion may be more prone to failure even after replacement. Regular flushing, corrosion inhibitors, and storage in a dry environment are essential.

---

### **Conclusion**

The Johnson 63718 motor pinion is a practical and cost-effective solution for restoring functionality to older Johnson outboard motors. Its compatibility, durability, and ease of replacement make it a strong choice for those maintaining or repairing classic or discontinued models. However, potential buyers should consider the age of the motor, the condition of surrounding components, and their own mechanical skills before purchasing.

For **new or heavily modified motors**, this part may not be the best long-term solution due to obsolescence risks. For **older, well-maintained outboards**, it remains one of the most reliable and affordable replacement options available.

### **Recommendation**

- You are repairing a classic or discontinued Johnson outboard motor.

- The motor is in good overall condition, and you have access to proper tools and maintenance.

- You plan to use it in a controlled environment (e.g., freshwater or with regular saltwater flushing).

- You are comfortable with basic mechanical work or have a trusted mechanic to assist.

- The motor is severely worn or has other failing components that would require additional repairs.

- You are unsure about the compatibility with aftermarket modifications.

- You cannot confirm the authenticity or quality of the part from the supplier.

- You are looking for a long-term solution for a modern or heavily upgraded outboard.

For best results, pair the purchase with a full inspection of the motor s gear system, including the lower unit, shaft, and propeller. Regular maintenance (oil changes, corrosion prevention, and proper storage) will maximize the lifespan of the pinion and the motor as a whole.
