That sounds like the dealer didn't install the mount correctly - no backing plate maybe?
@Bradford Abbott. I put them on my boat four years ago and they have been great, one of the best things I've added to the boat. Rock solid, no flex or movement. Way more flex and play in my Scotty swivel base, of which I've broken several (where the locking pin goes). Like most thingsk proper installation is key. In my case they are mounted through at least 1" of fibreglass with a 3/4" piece of starboard as a backing plate.
They are not for everyone - cost being the biggest downside - but I wouldn't have a boat without them now. I've got the BBQ mount, fender cleats and a separate base for my puller (in addition to the downrigger mount and rod holders) and they get used all the time. Their support is great too. Nice to see places are selling them up here now, when I got mine I had to order direct from Burnewiin.
