Tilt motor goes up fine, but does not go down. When I bought he boat a few weeks ago, the reservoir was empty. Added fluid, then up and down both worked. Down stopped working a day later. Switched relays, no change. To lower the outdrive, I have to loosen the hydraulic line and step on the outdrive. Can I bypass stuff to make sure the motor is good? Bench test maybe? Manual is very unclear on the whole tilt system. Don't think it could be pressure locked after I loosened lines, but maybe I'm missing something. Replaced the floor, tuned the motor, ready to test it out but this is stopping me!
