ABSTRACT:
A boat provides full operation even in shallow water utilizing an outboard motor. The boat includes a main hull, a displaceable transom to which the motor is mounted and a displaceable hull section. The displaceable transom is received in sliding engagement within two guide brackets mounted to the main hull. The displaceable hull section is connected to the displaceable transom by a hinge along a rear edge. The leading edge of the displaceable hull section is received and rests within a lip in the main hull. Actuator cylinders mounted in alignment with the guide brackets raise and lower the transom and the rear end of the displaceable hull section while the leading edge of the displaceable hull section pivots and slides in the lip. When the motor is raised for shallow water operation the displaceable hull section forms a flow channel for directing water to the propeller and intake port of the motor so as to prevent damage and provide proper and efficient water cooling.
