Abstract
An extension joint device for a marine drive comprises a first cylinder and a second cylinder which is telescopically extendable and retractable relative to the first cylinder to adjust a length of the extension joint. Together, the first and second cylinders define a sealed cylindrical cavity which is extended and retracted upon extension and retraction of the second cylinder relative to the first cylinder, respectively. an electrical connector extends through the extension joint, the electrical connector having a helical shape in the sealed cylindrical cavity which is extended and compressed upon extension and retraction of the second cylinder relative to the first cylinder. A slip ring, through which the electrical connector extends, is configured to permit rotation of a first portion of the electrical connector relative to a second portion of the electrical connector, thereby facilitating compression and extension of the helical shape.
