Abstract
An outboard motor includes a shift rod including a first rod, a second rod, and a joint. The first rod extends in a vertical direction. The second rod extends in the vertical direction and is located below the first rod. The second rod is disposed eccentrically with respect to the first rod. When viewed in a plan view, the second rod overlaps with at least a portion of the first rod or is in contact with the first rod. The joint connects the first rod to the second rod.
