Review OMC Nos Oem Johnson Evinrude Propeller Spacer

The **OMC 5031552 NOS Johnson/Evinrude Propeller Spacer** is a meticulously crafted, high-performance marine component designed to enhance the functionality and efficiency of outboard motors from Johnson and Evinrude, particularly those in the classic and vintage boating community. This **new-old-stock (NOS)** spacer is engineered to bridge the gap between the engine s lower unit and the propeller shaft, ensuring optimal alignment and reducing unnecessary stress on critical mechanical components. Constructed from durable, corrosion-resistant materials, this spacer is built to withstand the demanding conditions of saltwater and freshwater environments, making it an ideal choice for both recreational and performance-oriented boaters. Its precise dimensions and seamless fitment allow for improved propeller alignment, which can lead to better thrust efficiency, reduced vibration, and extended engine life. Whether restoring a classic Evinrude or upgrading an older Johnson outboard, this NOS spacer serves as a reliable solution for maintaining proper shaft alignment, preventing premature wear on the propeller and lower unit bearings, and ensuring smooth, consistent operation. Perfect for enthusiasts seeking authentic, high-quality replacement parts, this spacer embodies the reliability and precision that define Johnson and Evinrude s legacy in marine propulsion.

### **Pros and Cons of buying a OMC 5031552 NOS Johnson/Evinrude Propeller Spacer**

1. **Compatibility** This is a genuine **New Old Stock (NOS)** part designed specifically for **Johnson/Evinrude outboards**, ensuring a precise fit without modification. It is likely to be compatible with older models that originally used this part, reducing the risk of clearance issues or performance loss.

2. **Reliability** Since it is a **direct replacement part**, it should function as intended without unexpected failures. NOS parts are often sourced from inventory that was never installed, meaning they have not been exposed to wear from prior use.

3. **Performance Preservation** If your engine was originally equipped with this spacer, reinstalling it may restore **factory torque settings, vibration dampening, and proper propeller alignment**, which could improve smoothness and efficiency.

4. **Cost-Effective Alternative** Compared to a **new OEM part**, a NOS unit may be **cheaper**, especially if the original part was discontinued or became difficult to source. It can also be a budget-friendly option if you re restoring an older boat.

5. **Aesthetic & Historical Value** If you re working on a **classic or vintage boat**, using NOS parts helps maintain **authenticity** and may be preferred by enthusiasts who value original components.

6. **Ease of Installation** Since it s a direct replacement, installation should be straightforward, requiring only basic tools and no additional machining or modifications.

1. **Age & Wear** Despite being NOS, the part may still show signs of **aging** (e.g., minor corrosion, wear marks, or slight discoloration). While functional, it may not look as pristine as a new part.

2. **Limited Availability** NOS parts are **not always easy to find**, especially if the model is outdated. You may need to search through **specialty marine parts dealers, eBay, or collector forums**, which could take time.

3. **Potential for Counterfeit or Mismatched Parts** Since NOS parts are not mass-produced, there is a risk of **fake or incorrectly labeled items** being sold. Always verify the **part number, material, and condition** before purchasing.

4. **No Warranty** Unlike new OEM parts, NOS items typically come with **no warranty**, meaning you bear full responsibility for any failures or issues that arise.

5. **Possible Clearance Issues** If the spacer was modified in the past (e.g., drilled or machined), reinstalling it may cause **interference with other components**. A thorough inspection of the engine bay is recommended.

6. **Performance Variability** If the original spacer was **worn or improperly installed**, simply replacing it with a NOS unit may not fully restore performance. You may need to **check alignment, torque settings, and propeller balance** afterward.

7. **Higher Long-Term Cost** While initially cheaper, if the NOS part fails prematurely (due to age or improper handling), you may end up **replacing it sooner than a new part**, negating the cost savings.
