Cannot thank this forum enough for all the great inputs. I have a unique question regarding a noise coming from my 2003 SeaRay 420 throttle control. Upon start up of the starboard engine I am hearing a sound that is best described as an audible vibration sound. I am going to get a video of the sound this afternoon and will get it added to this post. It does lessen as the RPM is increased.
Has anyone else experienced anything like this?

Ever heard this term?

“Cable Talk”

I definitely have experienced it with mechanical engines many times.

Apologies for the horrible explanation. Thanks for the help, I am wondering if this has to do with the engine sync system?

“audible vibration sound” ?

Hmmm, not sure I understand what you are getting at. The video should help.
