Mystery 50 hour service warning, Yamaha F200s

[seasick]

2020 F200s, Garmin 8616 MD, 6YC Information System
I am getting a recurring warning on my networked Garmin 8616 MFD that says the the 50 hour service is overdue. I just acknowledge the message to clear it from the screen for a while.
The problem is that there is no 50 hour service listed in the Yamaha manual nor can I find anyway to reset the interval. I tried resetting the 100 hour intervals using the 6YC display but the 50 hour warnings keep popping up.
According to the 6YC manual for twin engine applications, the service interval can not be changed and is set to 100 hours

You can set service intervals on the Yamaha page, read here
I remember to have to reset the service interval also on my 8412, when the message pops up only on your 8616 then it has to be reset there also. Either thru the Yamaha page or somewhere in the menu, last resort would to disable maintenance alarm if that can be done, have a look if you can do that.

Which Yamaha display do you have? Reset in newer displays under maintence interval. 50 is to change fuel filters in newer motors

Display is 6YC. There is a maintenance menu but it doesn't list a 50 hour item. In addition there is no option to add or change a maintenance reminder. The only option is to reset the current reminders and there is only one, the 100 hr reminder.. The paper user manual states that the intervals are set to 100 hours and can't be changed.
When the reminder pops up on the 8616, the only option on that screen as far as I have found, is to acknowledge the message and close the pop up message.

The motors are 2020 models.

Thanks for this info. I can't remember if I verified the dat in the 8616 Yamaha set up menu. Sounds promising.
