Extension joint for a marine drive

An extension joint device for a marine drive, the extension joint device comprising:

• a first cylinder;
• a second cylinder that is telescopically extendable and retractable relative to the first cylinder to adjust a length of the extension joint device;
• wherein 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 extending through the extension joint device, 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;
• and
• a slip ring through which the electrical connector extends, wherein the slip ring 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.
