Whatsup guys. Got my b*tchen new blue water bait tank. For those who have installed them before, randy told me to mount a couple pieces of starboard to the floor and then slip the tank over the top and drill bottom sides of the tank to the starboard. I can’t for the life of me find any starboard thick enough. There’s a 4” lip of the bait tank and something has to go behind it to screw in the sides of the bait tank. Any ideas?
