No the inverter isn't running I'm dockside and this is a new problem as
for years no buzzing with the old system. Even cleaned all the battery
terminals....When I remove the ground I have the buzzing gets worse
when replace its less but still there. I've even tried a larger ga
ground wire still there.


Maybe the new stereo is defective? Seems like you've about ruled
out everything else. Unless, of course, there's a new vessel in a slip
on either side of you that is broadcasting interference. Get a portable
little radio and walk around the dock close to neighboring vessels
and see if you get the buzz.

Neighbors are the same powerboats and nobody home.....If it is the new
receiver which I got on eBay then I'll just live with it. Seems every
time you upgrade on small piece of equipment you have to change a lot
of things....isn't technology great. I'm still convinced something
isn't grounded right maybe the amp but not sure where to attach another
ground except to the mounting screws

Yes, you should definitely ground the metal case. The ground wire for the
current (usually black) is not enough. There should be a screw or pin
on the metal case where you can connect a ground.
