Abstract: The marine cable bellows installation tool is a hand tool. The marine cable bellows installation tool is configured for use in inserting a control cable through a cable bellow. The marine cable bellows installation tool inserts the control cable through the cable bellow such that the control cable will not damage the cable bellow during the process. The marine cable bellows installation tool comprises a tapered tube, a chase tube, and a striking tool. The tapered tube inserts into the cable bellow such that the tapered tube forms a barrier that protects the tapered tube from damage by the control cable. The striking tool is a momentum transfer device that provides the motive forces required to draw the control cable through the cable bellow. The chase tube is an intermediary that protects the cable bellow from any potential impact damage commonly associated with percussive procedures.
