my boat is 17ft ranger with a mercury 150 on a 6 inch jackplate, my boat seems to set low on the left side while running down the lake. someone told me to raise my motor on the opposite side. i lost my steering tab a couple of weeks ago but that wouldnt cause it to torque low on one side would it.i have one battery on each side of the boat so weight is even. it runs low whether im by myself or have 2 people in the boat. what do i need to adjust.
