We had a rainstorm when we were out of town and the boat had filled with water while docked at the lake. Since then the tilt and trim has not worked. Connections have been inspected for corrosion. Could you please give me some ideas on where to start tracking down the problem. We have replaced the realys with no luck and I am trying to not have to buy a whole new box if I don't have to. Any ideas would be helpful. I am writing this for my husband while he is at work and I will try to explain things the best I can. Thanks, Andrea
