Abstract: A motor mount bracket for use in combination with a twin-hull sail boat, to which an outboard motor can be affixed, and which can support the motor in a running location with its screw in the water between the hulls, or in a stowed location with its screw out of the water. The bracket has a stand-off for attachment to the aft-most cross-strut of the sail boat, and an arm pivotally connected at its forward end to the stand-off at a pivot-point that is below and somewhat aft of the cross-strut. A motor mount is at the aft-end of the arm. The arm pivots through a vertical sweep between the running location and the stowed location.
