The tilt motor runs but will not raise drive. It can be raised by picking up on it and it raises when in the water and in reverse. Is this a clutch problem, or a coupling problem? Running it in reverse when tilted up could cause damage too. I have not checked the solenoids or taken the clutch cover off to check it's condition. Maybe the motor is just weak but why would that cause it to raise when reversing? I am now rambling on, any help would be appreciated as no one wants to work on this old of a boat
