Engine data recording
This model's ECM stores certain engine data to assist in the diagnosis of malfunctions and for research, statistical analysis and
development purposes.
Although the sensors and recorded data will vary by model, the main data points are:
 Engine status and engine performance data
This data will be uploaded only when a special Yamaha diagnostic tool is attached to the engine, such as when maintenance
checks or service procedures are performed.
Yamaha will not disclose this data to a third party except in the following cases. In addition, Yamaha may provide engine data
to a contractor in order to outsource services related to the handling of the engine data. Even in this case, Yamaha will require
the contractor to properly handle the engine data we provided and Yamaha will appropriately manage the data.
 With the consent of the boat owner
 Where obligated by law
 For use by Yamaha in litigation
 For general Yamaha-conducted research purposes when the data is not related to an individual engine or owner
