Using this solenoid is easy. Just install it in your Mercruiser or Mercury system as per the standard installation process. Make sure the power supply is 12 volts. When it comes to maintenance, keep it clean and dry. Check for any loose connections regularly. If you encounter any problems, don't return it to the store. Instead, reach out to the manufacturer directly. And remember, it comes with a 12 - month part and labor warranty, so you're covered for a while.
