Several embodiments of marine outboard drives including depth finders attached as a unit to the outboard drive. In each embodiment, the depth finder includes a transmitter/receiver that is carried by the lower unit in proximity to and beneath a cavitation plate for protection from underwater objects and for facilitating removal. The outboard drive is pivotally supported by a hollow steering shaft and a conductor extends through the hollow steering shaft for transmitting signals from the transmitter/receiver to a display that is mounted on the outer cowling. In some embodiments, the display is mounted on the front of the outer cowling and on others is pivotally supported on the top of the outer cowling. In all embodiments, the display is resiliently supported.
