Looking for advice/pics on installing a second graph on my 2013 Cougar.. Presently have a 958C up front and want to add either a Helix or Onix 10 inch .. Means I will have to attach on deck.. Assume, but looking for advice on using “big” ram mount but unsure if that mount will handle the stress on the deck or if I need to put a “plate on the deck and below the deck” via rod locker to make sure its secure.. Thoughts and pics will be helpful.. Thanks to my BC friends for the assistance. Randy/Michigan (where its still winter and hard water !)
