The OMC 309247 Johnson/Evinrude spring (part number 0304573) is an idle adjustment component used in outboard marine engines. Here are some potential pros and cons of buying this part:

Pros:

1. OEM (Original Equipment Manufacturer) part: This spring is manufactured by the same company that originally equipped your engine, ensuring a perfect fit and compatibility with other engine components.

2. Improves idle stability: A properly functioning idle adjustment spring allows your engine to maintain a consistent idle speed, improving overall engine performance and reducing the risk of stalling.

3. Easy installation: According to customer reviews, this part is relatively simple to install, taking around 30 minutes to an hour.

4. High-quality materials: Johnson/Evinrude is known for producing durable marine engine components, and this spring is no exception.

Cons:

1. Cost: This OEM part may be more expensive than aftermarket alternatives, which could be a deterrent for some buyers.

2. Availability: Depending on your location and the availability of this part at local marine engine suppliers, you may need to order it online, which could lead to longer wait times.

3. Potential for additional issues: If your engine's idle adjustment issue is caused by something other than a worn or damaged spring, replacing this part alone may not solve the problem.

Conclusion:

The OMC 309247 Johnson/Evinrude spring (part number 0304573) is a high-quality, OEM component designed to improve idle stability and maintain consistent engine performance. However, its cost and potential availability may be drawbacks for some buyers. Ultimately, if you're experiencing issues with your engine's idle speed and are confident that a worn or damaged idle adjustment spring is the root cause, this part may be a worthwhile investment for maintaining the overall health and functionality of your marine engine.

Recommendation:

Before purchasing this part, I would recommend checking with your local marine engine supplier to see if they have it in stock. If not, you may want to consider ordering it online from a reputable marine engine parts supplier to ensure you're getting an authentic OEM part. Additionally, it may be worth investigating other potential causes of your engine's idle issues, such as a carburetor problem or a vacuum leak, to determine if replacing the idle adjustment spring alone will solve the issue.
