replacing all bellows. read great instructions from trent and others on how to do it. need help now. pulled the outdrive (1978, 250 CI IL6 Merc), exhaust bellows, and shift cable bellows. pulled plastic clevis in boat at upper end of lower shift cable. pulled set screw in shift slider. cable core moves about 6 inches both directions, but doesn't want to come out. one post says to remove the stainless steel tube. is this the tube in the boat that the brass barrel screws onto? another post said to pull slider at outdrive. mine is held on by a cylinderical clamp that cannot be removed except by cutting cable. and what about the brass fitting in the gimbal that the shift cable runs into? does it need to come out? help please!!
