Review OMC Johnson Evinrude Slow Speed Adjustment Link Arm Assembly fits 1972

The **OMC 0315922 Johnson Evinrude 1972 Slow Adjustment Link** (part number **0313792 Arm**) is a precision-engineered component designed specifically for older Johnson/Evinrude outboard motors, particularly those from the 1970s era, ensuring smooth and reliable throttle control. This slow-adjustment linkage system is a critical part of the motor s drive mechanism, allowing the operator to gradually modulate engine speed without abrupt shifts or jerks, which is essential for maintaining control during slow-speed maneuvers, such as docking, trolling, or navigating tight spaces. Crafted from durable, corrosion-resistant materials, the linkage is built to withstand the demands of marine environments, including exposure to saltwater, humidity, and constant mechanical stress. The **0313792 Arm** serves as the pivotal connection point between the throttle lever and the motor s internal throttle valve, ensuring precise and responsive adjustments while minimizing wear over time. This part is particularly valuable for restoring or maintaining vintage outboards, as it helps preserve the original functionality of the motor s throttle system, reducing the risk of binding or failure. Whether used in a classic fishing boat, a restored classic outboard, or a collector s piece, this linkage ensures that the motor operates with the same smooth, controlled performance it was designed for decades ago. Proper installation and regular maintenance of this component will extend the lifespan of the motor and enhance the overall driving experience.

### **Pros and Cons of buying a OMC 0315922 (Johnson Evinrude 1972 Slow Adjustment Link) and 0313792 Arm**

#### **Overview**

The **OMC 0315922** is a slow-adjustment link kit designed for older **Johnson/Evinrude outboard motors**, particularly those from the 1970s, while the **0313792 arm** is a replacement steering arm for the same engine models. These parts are often sought after for restoring or maintaining vintage outboards, but they come with both advantages and drawbacks.

---

### **Pros**

1. **Compatibility with Classic Engines**

- These parts are specifically designed for **1972 Johnson/Evinrude outboards**, ensuring a proper fit without modifications. This is crucial for maintaining original functionality and performance in restored engines.

2. **Authentic Restoration Potential**

- For collectors and enthusiasts restoring original engines, these parts help preserve the **historical accuracy** of the build. Using OEM components reduces the need for aftermarket substitutions that may alter the engine s character.

3. **Durability and Reliability**

- Original Marine (OMC) parts are built to the same standards as the factory components, meaning they should last as long as the original parts if properly maintained. This is especially valuable for engines used occasionally or in demanding conditions.

4. **Ease of Installation**

- Since these parts are direct replacements, they should integrate smoothly with the existing drivetrain. No major modifications to the engine or boat are typically required, making repairs simpler for DIYers.

5. **Availability of Spare Parts**

- While not as common as modern parts, OMC still supplies aftermarket components for older outboards. This means replacement parts for other systems (e.g., throttle linkages, shift linkages) may still be accessible.

6. **Potential for Increased Value**

- Restoring an engine with original or high-quality replacement parts can **enhance its resale value** for collectors. A fully functional, well-maintained 1972 Johnson/Evinrude with OMC parts may fetch a premium in the vintage market.

7. **Compatibility with Original Controls**

- The slow-adjustment link (0315922) and steering arm (0313792) work seamlessly with the original **throttle, shift, and steering mechanisms**, ensuring smooth operation without compatibility issues.

---

### **Cons**

1. **Limited Availability and Lead Times**

- OMC parts for older engines are **not mass-produced**, meaning they may be harder to find than modern replacements. Ordering may require special ordering through marine supply houses, leading to **longer wait times** (weeks or even months).

- Some dealers may no longer stock these parts, forcing buyers to rely on online suppliers or eBay, which can be risky due to counterfeit or mismatched components.

2. **Higher Cost Relative to Modern Alternatives**

- Original or reproduction OMC parts are often **more expensive** than generic aftermarket replacements. For example, a slow-adjustment link and steering arm kit may cost significantly more than a universal throttle linkage from a big-box retailer.

- The cost can be a barrier for budget-conscious restorers who might opt for cheaper (but potentially lower-quality) alternatives.

3. **Potential for Wear or Failure Over Time**

- Even OMC parts are not immune to wear, especially if the engine is used frequently or in harsh conditions. The **slow-adjustment link** and **steering arm** may eventually require lubrication or replacement, adding to long-term maintenance costs.

- Rust and corrosion are common in older parts, so buyers should inspect for damage before installation.

4. **Limited Customization Options**

- Unlike modern outboards, these parts do not offer **adjustable features** (e.g., variable throttle response or electronic controls). The slow-adjustment link is designed for mechanical operation only, which may not suit modern driving preferences.

- If the engine is being modified for performance tuning, these parts may not align with aftermarket upgrades.

5. **Difficulty Finding Qualified Mechanics**

- Not all marine mechanics specialize in **vintage outboards**. Finding a technician familiar with 1970s Johnson/Evinrude drivetrains can be challenging, increasing the risk of improper installation or diagnosis.

- DIY installation is possible but may require research into older service manuals or forums.

6. **Risk of Counterfeit or Mismatched Parts**

- Due to their age, OMC parts are sometimes **reproduced or counterfeited**, leading to poor-quality fakes that fail prematurely. Buyers should purchase from **reputable dealers** with return policies and verify authenticity (e.g., checking part numbers and materials).

- Some aftermarket "compatible" parts may not fit perfectly, causing binding or misalignment.

7. **Environmental and Handling Challenges**

- Older outboards were not designed with modern **ergonomics or environmental standards** in mind. The slow-adjustment link, for example, may require more physical effort to operate than a modern quick-adjust system.

- If the engine is being used in **saltwater**, corrosion resistance may be a concern unless the parts are properly treated (e.g., with marine-grade lubricants).

### **Ending Conclusion**

The **OMC 0315922 slow-adjustment link and 0313792 steering arm** are **excellent choices for restoring or maintaining a 1972 Johnson/Evinrude outboard** if authenticity, durability, and long-term reliability are priorities. They offer a **direct replacement solution** that preserves the engine s original character and ensures compatibility with vintage controls. However, the **higher cost, limited availability, and potential for counterfeit parts** make them less ideal for casual or budget-conscious buyers.

For **collectors, restorers, or enthusiasts** who value historical accuracy and are willing to invest in quality, these parts are a **strong recommendation**. For **casual boaters or those on a tight budget**, weighing the pros and cons against modern alternatives (e.g., universal throttle linkages or aftermarket kits) may be more practical.

---

### **Final Recommendation**

- You are **restoring a vintage Johnson/Evinrude outboard** and prioritize original or high-quality reproduction components.

- You have **access to a reliable dealer** and are willing to wait for shipping.
