I just replaced my tilt motor. It was only a 30 min. job. You do not need to remove the tilt tube and, raise the motor and unbolt a transom bracket.

All you have to do is rotate the motor up until the ram is at the top of the stroke, support the motor with the swivel locks, remove the pin which attaches the main ram to the motor, and rotate the motor over center on the transom to support it's weight. Then the entire hydraulic system will move enough to access all four tilt motor bolts. Piece of cake.
