New to boating, was just curious if this is normal or the gimble and/or ujoints, something else?? Video starts with the noise happening, i adjust the revvs and it goes away, play with it and the noise comes and goes, you can hear again steady when the video ends..

The audio is lack luster but hopefully y'all can hear what I'm talking about.
