Description:
BACKGROUND OF THE INVENTION 
       [0001]    1. Field of the Invention 
         [0002]    The present invention relates generally to water craft and, more specifically, to water craft having an outboard motor with an auxiliary motor attached thereto by means of the bracket of the present invention. The bracket has an auxiliary motor mounting plate with divergently extending arms to receive the body of the outboard motor and fixed thereto. A third arm extends from the mounting plate extending downwardly and is also fastened to the outboard motor. Additionally the reason the auxiliary motor can be mounted rigidly is that the main motor has a five inch longer shaft, allowing the auxiliary motor to be mounted so when in a plane the auxiliary motor is out of the water, and when dropped down from a plane, it is deep enough to prevent cavitation. Also the depth is set by the trim on the main motor. 
         [0003]    2. Description of the Prior Art
