Abstract: An apparatus for automatically raising and lowering boat motors includes a mounting configuration that allows the motor to move up out of the water and down into the water. A hydrofoil is connected with the motor. When the boat is propelled by a second motor, the water pushes up on the hydrofoil, forcing the first motor up out of the water. A locking device can be used to maintain the first motor in the up position. The locking device can be disengaged to allow the motor and hydrofoil to fall into the water. Alternatively, the motor and hydrofoil can be maintained in the up positon by the force of water against the hydrofoil. When the second motor is shut down the motor and hydrofoil automatically drop into the water.

Abstract: An apparatus mounts a sonar transducer to a boat. The apparatus includes a tubular member with a handle at one end and a transducer mounting bracket at the other end. The transducer mounting bracket is adapted to couple to a sonar transducer. Both the handle and the transducer mounting bracket are pivotally coupled to the tubular member and to each other by a linkage rod. By moving the handle up or down, the transducer mounting bracket will move correspondingly to a new elevational orientation. In one embodiment, the tubular member is received by a cylindrical bore in a ball; the ball is mounted to the boat. By turning the handle to one side, the tubular member and the transducer mounting bracket will correspondingly turn to a new azimuthal orientation. In another embodiment, the tubular member is received by a sleeve mounted in a pivotable ball. The tubular member can move relative to the sleeve. Locking nuts on the sleeve, when tightened, prohibit movement of the tubular member.
