Abstract: An improved motor support is provided which securely holds a motor in a predetermined position and has its length continuously adjustable over a range of lengths. The motor support comprises a first bracket which is attached to the bottom portion of a motor mount, a second bracket which is attached to the lower portion of an outboard motor, and an adjustable length support arm which is secured between the first and second bracket. In one embodiment, the brackets comprise T-shaped members having hollow channels in the base and threaded channels perpendicular to the hollow channels. Additionally, the adjustable length support arm may have a first and second threaded region at respective ends of said arm for attaching the arm to the brackets. These threaded regions may be utilized to adjust the overall length of the motor support.
