### **Pros and Cons of buying a Johnson/Evinrude 0173974 NOS OEM Outboard Motor Switch (Part Number 173974)**

1. **New Old Stock (NOS) Quality** The switch is described as NOS, meaning it is unused but may have been stored for an extended period. If properly preserved, it could still function as new, offering reliability similar to a brand-new part.

2. **Original Equipment Manufacturer (OEM) Part** Being an OEM component ensures compatibility with the intended Johnson/Evinrude outboard model. This reduces the risk of fitment issues or performance problems that generic or aftermarket parts might introduce.

3. **Reliability and Durability** Johnson/Evinrude outboard motors are known for their robust construction. A genuine switch from this brand is likely to be built to withstand the demands of marine use, including exposure to moisture and vibration.

4. **Ease of Installation** Since it is an OEM part, wiring and mechanical connections should align with the original design, simplifying installation compared to aftermarket alternatives that may require modifications.

5. **Long-Term Performance** A well-maintained NOS switch should provide reliable operation over time, reducing the likelihood of sudden failures that could disrupt boating activities.

6. **Resale Value** If the part remains in good condition, it may retain some value in the used market, making it a potentially sound investment for future repairs or upgrades.

---

1. **Age and Storage Conditions** While labeled NOS, the part may have been stored for years, potentially exposing it to environmental factors like moisture, dust, or temperature fluctuations. This could lead to corrosion, degraded wiring, or mechanical wear, even if it appears unused.

2. **Potential for Hidden Damage** Without a thorough inspection, internal components (e.g., contacts, wiring, or seals) may be degraded. Testing the switch before installation is critical to avoid functionality issues.

3. **Cost** NOS/OEM parts are often priced higher than aftermarket alternatives due to their perceived quality and authenticity. If the budget is tight, this could be a significant drawback.

4. **Limited Availability of Documentation** Unlike new parts, NOS items may not come with updated manuals or installation guides. Researching the part s specifications and installation process beforehand is essential.

5. **Compatibility Concerns** While OEM parts are designed to fit, slight variations in wiring harnesses or mounting brackets between models or years could require additional effort to ensure a perfect fit.

6. **No Warranty or Return Policy** NOS parts are typically sold as-is, with no manufacturer warranty or return options. If the part fails shortly after purchase, the buyer bears the full responsibility for replacement or repair costs.

7. **Potential for Counterfeit NOS Parts** There is a risk of purchasing a part labeled as NOS that is actually refurbished, reconditioned, or even fake. Buying from a reputable dealer with a track record of authenticity is crucial.

The Johnson/Evinrude 0173974 NOS OEM outboard motor switch is an attractive option for boaters seeking reliability and compatibility with their original equipment. Its primary advantages lie in its potential for high performance, ease of installation, and alignment with the manufacturer s standards. However, the risks associated with age-related degradation, lack of warranty, and the possibility of hidden issues must be carefully considered.

For those who prioritize authenticity and long-term reliability and can afford the higher cost, this part is a strong choice **provided it is thoroughly inspected for functionality before installation**. Conversely, if budget or risk tolerance is a concern, a new OEM part or a high-quality aftermarket alternative may be preferable.

---

1. **Verify the Part s Condition** Before purchasing, request detailed photos or a video inspection of the switch to confirm it is free of corrosion, damage, or wear. Test the switch (if possible) to ensure it operates correctly.

2. **Purchase from a Trusted Seller** Buy from a well-reviewed dealer with a reputation for authenticity, such as a marine parts specialist, Johnson/Evinrude authorized distributor, or a seller with verifiable feedback.

3. **Compare with New OEM Options** If the price of the NOS part is significantly higher than a new OEM switch, weigh the value against the potential savings. A new part may offer peace of mind with a warranty and no risk of hidden issues.

4. **Consider Aftermarket Alternatives** If the NOS part is unavailable or too expensive, research reputable aftermarket brands (e.g., Seafoam, Raymarine, or other marine-grade switch manufacturers) that offer compatible, warrantied replacements.

5. **Budget for Testing and Installation** Account for the cost of testing the NOS part (e.g., multimeter check for continuity) and professional installation if needed, as DIY risks may outweigh the benefits.

**Final Verdict:** The Johnson/Evinrude 0173974 NOS switch is a viable choice for experienced boaters who can assess its condition and are willing to accept the associated risks. For most casual or budget-conscious buyers, a new OEM or high-quality aftermarket switch may offer a more balanced solution. Always prioritize functionality and compatibility over cost when selecting critical marine components.
