YDIS Smart is a free application software that can diagnose problems with Yamaha outboard motors. The app allows the user to perform various tests on the motor, diagnose the problem and get information on how to fix it. The software works by sending diagnostic data to the server, which sends back the results in a simple format that the user can read. The app also allows the user to check the performance of the motor, check if it is overheating, and see if it is undercooled.

The software is designed for use by a Yamaha authorized dealer. If you are not a dealer, you should not download the application.
