Motorboats are a great way to enjoy the water, but they need to be running properly for you to stay safe and have fun. The Electronic Control Module (EMM) is an important part of an Evinrude engine and if it’s not working correctly, you’ll need to know how to tell. This article will provide an overview of the Evinrude EMM, how to tell if it’s bad, and what to do if you need to replace it.
What is an Evinrude EMM?
The Evinrude EMM is a computerized control module that monitors and regulates the operation of the engine. It’s responsible for controlling the fuel injection system, ignition system, and other engine operations. It also monitors the engine performance, fuel efficiency, and emissions.
Signs that Your Evinrude EMM is Bad
There are several signs that your Evinrude EMM may be bad. These include:
1. Engine Misfires
If your engine is misfiring, it could be a sign that your EMM is bad. If you notice that the engine is running erratically or has trouble starting, it could be a sign that the EMM is not working correctly.
2. Poor Fuel Economy
If you find that your boat is not getting the fuel efficiency that it used to, this could be a sign that the EMM is not working correctly. Poor fuel economy can be caused by a number of things, including a bad EMM.
3. Engine Overheating
If your engine is overheating, it could be a sign that the EMM is not working correctly. The EMM is responsible for controlling the fuel injection system, and if it’s not working correctly, it can cause the engine to run hotter than it should.
How to Test Your Evinrude EMM
If you suspect that the EMM is bad, there are a few ways to test it. The first is to use a diagnostic scanner to check the engine codes. If the codes indicate that there is an issue with the EMM, then it’s likely that the EMM is bad and needs to be replaced.
The second way to test the EMM is to use a multimeter. A multimeter can measure voltage, resistance, and other electrical values. To test the EMM, you’ll need to connect the multimeter to the EMM and then measure the voltage and resistance values. If the values are not within the expected range, then the EMM is likely bad and needs to be replaced.
What to Do if Your Evinrude EMM is Bad
If you have determined that your EMM is bad, the first thing that you should do is contact your local Evinrude dealer. They will be able to provide you with a replacement EMM and help you install it. It’s important to make sure that the replacement EMM is compatible with your engine, so make sure to ask for help if you’re not sure.
