I have a tower from Tahoe. It is not like that though. It is black and more slanted. I have no issues with mine swaying side to side. The tower is swaying back and forth? Can you explain more about it, like is it swaying at the top or from where it is attached to the boat?
I have installed towers on new boats. Worked for dealer. Make sure mounts should have backing behind them.. I have had new boats that the didn't match up and had to fix. The one i had to fix used 3/4 backing and at least a foot lone. Used marintex to fill voids and hold in place.
Mine came with it on when I purchased the boat. I would think that a tracker dealership could order one from the factory and install it for you. Might want to call one if you have one near you.
My 06 has a factory tower, but it looks like the mounting pads are different. I dont have any real side-to-side sway, but it has some decent backing, too.
