I was wonderin if anyone has put the 7" seat pedestals on their jon boat. I have a 12' jon and I want the seats a little higher so I don't have to touch my knees to my chin just to get turned around. Plus, I'm going to put in a plywood floorboard in so I'll lose another few inches. Would this be safe? Half the time when I'm bass fishin, I'm standing anyway and the boat is stable, but if I'm catfishin then I'm sittin down. Any thoughts?
