I will be running at 3600 RPM and one of my engines loses 200-300 rpm and a few seconds later it goes back up to 3600. I have changed all gas filters and plugs. What else can I check?
I get the same problem with YAM 115 4 strokes. No idea. I'm going to call yamaha b/c im under warranty and my engines are brand new. less than 40 hours
