My 1985 GT-150 has about an inch of up and down slack.I can lift up on the back of the skeg and the play seems to be coming from the bottom of the trim cylinder where it is mounted to the motor bracket.There is also a little play where the tilt tube pin connects to the motor.Is there a bushing that can wear out in the bracket where it connects? The whole cylinder and tube moves when I lift up on the motor. Thanks for any help!
