Review JOHNSON EVINRUDE OMC Cam Follower 1968-1976 40 Hp fits 1983–1986
The **Johnson Evinrude OMC Cam Follower (Part #0376477 / 376477)** is a precision-engineered component designed specifically for the iconic 40 horsepower outboard motors manufactured between **1968 and 1976**, as well as select models from **1983 to 1986**. This critical cam follower plays a vital role in the internal valve train system, ensuring smooth and reliable operation of the engine s intake and exhaust valves. Crafted from high-quality, heat-treated steel, this component is engineered to withstand the demanding stresses of high-performance marine applications, where durability and performance are paramount. The cam follower s hardened surface and precision-ground shape minimize wear on the camshaft lobes, reducing friction and extending the lifespan of the entire valve train assembly. Whether you re restoring a classic Johnson Evinrude or maintaining a vintage boat, this OEM replacement part guarantees a seamless fit and optimal engine performance, allowing the motor to deliver the smooth, responsive power that enthusiasts expect from these legendary outboards. Proper installation of this cam follower is essential for maintaining proper valve clearance and preventing premature engine wear, making it a must-have for any serious mechanic or boat owner seeking to preserve the integrity of their 40 HP Evinrude.
### **Pros and Cons of buying a Johnson/Evinrude OMC 0376477 Cam Follower (376477) for 1968 1976 & 1983 1986 40 HP Outboards**
#### **Pros:**1. **Compatibility** This part is designed specifically for the Johnson/Evinrude 40 HP outboards from the late 1960s to mid-1980s, ensuring a proper fit without modification.
2. **Reliability** Cam followers are critical components for valve train operation. A high-quality replacement ensures smooth engine function and prevents premature wear on camshafts and valves.
3. **Prevents Engine Damage** A failing cam follower can cause excessive noise, poor performance, or even catastrophic valve failure. Replacing it proactively avoids costly repairs.
4. **Aftermarket Availability** Since this is a widely used part, it is relatively easy to source, even from specialty marine suppliers or online marketplaces.
5. **Cost-Effective** Compared to full engine rebuilds or replacements, a single cam follower is a low-cost solution for maintaining an older outboard.
6. **Improves Performance** A properly functioning cam follower ensures optimal valve timing, which can restore power and efficiency to an aging engine.
7. **Durability** Modern aftermarket cam followers are often made from high-quality materials (e.g., hardened steel or bronze) that outlast original OEM parts.
#### **Cons:**1. **Age of the Engine** If the outboard is from the 1960s or early 1980s, other components (e.g., bearings, seals, or fuel system parts) may also be worn and require attention.
2. **Potential Misalignment** If the camshaft or lifters are excessively worn, replacing just the cam follower may not fully resolve noise or performance issues.
3. **Installation Complexity** Removing and installing a cam follower requires disassembling the valve train, which may be challenging for inexperienced DIYers.
4. **Compatibility with Modified Engines** If the engine has been modified (e.g., camshaft upgrades), the stock cam follower may not be ideal and could limit performance gains.
5. **Quality Variability** Some aftermarket parts may not match the durability of OEM components, especially if purchased from unknown or low-quality suppliers.
6. **Additional Wear Indicators** If the cam follower is failing, other parts (e.g., lifters, pushrods, or camshafts) may also be nearing failure, requiring a more thorough inspection.
7. **Rust and Corrosion** Older outboards may have internal corrosion, which could affect the cam follower s longevity even after replacement.

### **Conclusion**
Replacing the **Johnson/Evinrude OMC 0376477 cam follower (376477)** in a 1968 1976 or 1983 1986 40 HP outboard is a **wise preventive maintenance step** if the engine is showing signs of cam follower wear (e.g., ticking noises, rough idle, or valve train rattles). This part is **critical for long-term engine health** and can prevent more expensive failures.
However, the decision should be part of a **broader assessment** of the outboard s condition. If the engine is otherwise in good shape, the replacement is a **low-risk, high-reward** upgrade. If the outboard is older and neglected, consider **inspecting or replacing additional components** (e.g., lifters, seals, or bearings) to avoid recurring issues.
---
### **Recommendation**
1. **Verify Symptoms** Confirm that the noise or performance issue is indeed from the cam follower (not lifters, pushrods, or camshaft wear).
2. **Source a Quality Part** Purchase from a reputable supplier (e.g., **OMC Marine, Marine Parts Warehouse, or eBay from verified sellers**) to ensure authenticity and durability.
3. **Inspect Related Components** While replacing the cam follower, check for **lifter wear, pushrod condition, and camshaft polish**. Replace any worn parts to maximize longevity.
4. **Follow Installation Guidelines** Ensure proper lubrication and alignment during installation to avoid premature failure.
5. **Consider Professional Help** If unsure about disassembly or valve train maintenance, consult a **marine mechanic** to avoid mistakes.
6. **Evaluate Engine Health** If the outboard is **20 years old**, weigh the cost of repairs against the engine s remaining usefulness. For high-mileage boats, a **full rebuild or replacement** may be more cost-effective in the long run.
**Final Verdict:** **Buy and replace the cam follower** if the engine is otherwise sound, but **do not overlook related components** to ensure a lasting fix. If the outboard is severely worn, prioritize a **comprehensive inspection** before committing to repairs.
