I purchased this boat knowing that the tilt motor was froze and I am saving to have it replaced. My question is there any way to let the hydrolics down so the boat will go without catching air. It started to work for a while, then quit when I added fluid. I just want the cylinders to retract for now. I already know about the screw to lower the motor, I just need to know how to let them in so I can lower it more.
