aint no fish up there...Depending on where the dent is , I bet your gona have to pull your motor and stand…don’t go hitting it with a big old hammer…that ill remove the dent but it will put several little dents where the hammer hit… like get a 2X6 2’ long and place it on the dent …put the foot of the highlift jack on that 2X6 get a good solid stick of lumber “4x4” that runs the width of the boat and put it on the lip of the jack and put you a another solid piece of lumber on the opposite side of the boat “like a 6’ 4X4” jack it out..do u know what im sayin???Swede Johnson SRA #1
