Hello,
I'm new to outboards, and boating.
I have just recently purchased a 22ft center console with a 97 Merc 200 EFI offshore on it.
I have used the boat for about 20 hours and everyhting was fine, until this weekend I took it out and towards the end of the day the motor had a really low idle and was rough. If I sat there in neutral it would idle low but would not be hitting on all cylinders, put it gear and it will stall. Anything over 1800 rpms it runs great.
I replaced the plugs,
changed all filters
Inspected the vapor seporator, it was clean no debris.
It seems like a sensor or electrical problem at low rpm.
Anybody have a suggestions
Thanks
Mike
