Yamaha SX 190 rough idle

I have a 2019 Yamaha 190 with a rough idle. It starts up fine and appears to run ok at higher speed. While sitting at the dock the engines rocks occasionally and sounds like it is misfiring. I changed the spark plugs with NGK last year. I checked the fuel injectors and they looked super clean. We run only ethanol free gas. If only I had access to the YDS version 2.0 I could run the diagnostics. Any suggestions or ideas would be welcomed
