I have a 1994 Merc 40hp. T The tilt trim resovior cracked. I replaced the motor and resovior. Motor runs but no lift when pressing the trim switch. I tried to bleed by lifting motor all the way up, adding fluid. I checked the manual release screw and its all the way in. Still no up or down. I was told these sytems are pretty much self bleeding. Any ideas of what might be wrong. Thanks to all for the help on this.
