RF Ground on 1999 Sea Ray 310 Sundancer

[skalita]

Good Day,
I will be installing a new Raymarine chartplotter to replace our old Raytheon 398 GPS/LORAN, and the installation instructions recommend grounding one of the wiring harness leads to the boats RF grounding point. Can anyone advise me where this RF grounding point is located.
Thanks.

Probably needs to be grounded to the Dynaplate grounding shoe that Sea Ray installs if the boat is ordered with nav gear or the nav gear prep package. I forget if Sea Ray connected the Dynaplate to the bonding system alone or if they brought a bonding wire up to the helm. Look for a green wire of about 10 gauge or so behind the helm near the other connection blocks. That would be it
