An outboard motor support device includes a transom connection mechanism, a pivot joint, and a motor support. The transom connection mechanism engages directly with a transom bracket to maximize stability and is configured to provide a consistently correct angular orientation of the motor support relative to the motor during use. In particular, the pivot joint adjustably aligns to the motor is a desired orientation during assembly to ensure a firm and “nested” engagement with the lower unit of the motor in the motor support. The motor support can be designed to fit specific motors, allowing for maximum stability and maximum surface area contact when properly aligned and engaged with the motor. The present outboard motor support device is formed as a single unit that provides vertical support as well as horizontal stabilization to the motor during transit, thereby also preserving the transom brackets and tilt/trim mechanism of the motor.
