Welcome to our comprehensive guide on how to reset the Evinrude EMM. The Evinrude EMM (Engine Management Module) is a crucial component of your outboard motor, controlling various functions and ensuring optimal performance. However, like any electronic device, it may encounter issues from time to time. In this article, we will walk you through the necessary steps to reset the Evinrude EMM and get your outboard motor running smoothly again.

Understanding the Evinrude EMM

Before diving into the reset process, it's important to have a basic understanding of what the Evinrude EMM is and how it works. The EMM is responsible for controlling fuel injection, ignition timing, and other essential functions of your outboard motor. It constantly monitors various sensors and inputs to ensure optimal performance and efficiency.

Why Resetting the Evinrude EMM is Necessary

Resetting the Evinrude EMM can be necessary for a variety of reasons. It can help resolve issues such as rough idling, poor acceleration, or even a complete engine shutdown. By resetting the EMM, you essentially clear any stored error codes or glitches that may be affecting its performance.

Steps to Reset the Evinrude EMM

Now that we understand the importance of resetting the Evinrude EMM, let's dive into the step-by-step process:

Step 1: Turn Off the Ignition

Before attempting any reset procedures, it's crucial to turn off the ignition and disconnect the battery. This ensures your safety and prevents any accidental damage to the EMM or other electrical components.

Step 2: Locate the EMM

The Evinrude EMM is typically located on the side of the outboard motor, near the top. It is a rectangular module with various connectors and wiring leading to it. Take a moment to familiarize yourself with its location and appearance.

Step 3: Disconnect the EMM Connectors

Once you have located the EMM, carefully disconnect all the connectors attached to it. These connectors may vary in number and type, depending on the specific model of your outboard motor. Use caution and ensure you don't damage any of the connectors during this process.

Step 4: Wait for a Few Minutes

After disconnecting the EMM connectors, we recommend waiting for a few minutes. This allows any residual electrical charge to dissipate and ensures a more effective reset.

Step 5: Reconnect the EMM Connectors

Once the waiting period is over, reconnect all the EMM connectors to their respective ports. Ensure a secure and proper connection to avoid any issues in the future.

Step 6: Reconnect the Battery

Now that the EMM connectors are securely in place, it's time to reconnect the battery. Double-check the polarity and make sure the connections are tight. This step is crucial, as a weak battery connection can cause further issues with the EMM.

Step 7: Turn On the Ignition

With the battery reconnected, you can now turn on the ignition. Allow the Evinrude EMM to initialize and perform its self-checks. You may hear some clicking or humming noises during this process, which is normal.

Step 8: Check for Error Codes

After the EMM has initialized, check for any error codes or warning lights on the instrument panel. These codes can provide insight into any underlying issues that may still persist. Consult your outboard motor's manual to decipher the specific error codes.

Step 9: Clear Error Codes (if necessary)

If you find any error codes after the reset, you may need to clear them manually. Some outboard motors have a reset function built into the instrument panel, while others may require specialized diagnostic tools. Refer to your motor's manual or consult a professional if you're unsure about this step.

Step 10: Test the Outboard Motor

With the Evinrude EMM reset and any error codes cleared, it's time to test your outboard motor. Start the engine and pay attention to its performance. Ensure smooth idling, responsive acceleration, and stable operation at various speeds. If any issues persist, further troubleshooting may be required.

Troubleshooting Tips for Evinrude EMM

While resetting the Evinrude EMM can resolve many issues, some problems may require further troubleshooting. Here are a few tips to help you diagnose and address common EMM-related problems:

1. Check for Loose Connections

In some cases, a loose connection can cause issues with the EMM. Inspect all the wiring and connectors leading to the EMM for any signs of damage or looseness. Tighten any loose connections and replace any damaged wiring if necessary.

2. Monitor Sensor Readings

The EMM relies on various sensors to gather data for optimal engine performance. Use a diagnostic tool or consult your outboard motor's manual to monitor sensor readings. Look for any abnormalities or erratic readings that may indicate a faulty sensor.

3. Clean Fuel System and Injectors

A clogged or dirty fuel system can adversely affect the EMM's performance. Regularly clean the fuel system and injectors to prevent any blockages or fuel flow issues. This can help ensure consistent fuel delivery and prevent potential EMM problems.

4. Consult a Professional

If you're unable to resolve EMM-related issues on your own, don't hesitate to consult a professional marine mechanic or contact the Evinrude customer support team. They can provide expert guidance and assistance in diagnosing and fixing complex EMM problems.


Resetting the Evinrude EMM can be a simple yet effective solution to many outboard motor issues. By following the step-by-step process outlined in this guide, you can reset the EMM and get your engine running smoothly again. Remember to exercise caution and consult a professional if you're unsure about any step or encounter persistent problems. With proper maintenance and occasional resets, your Evinrude outboard motor will continue to deliver reliable performance for years to come.
