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 position by the force of water against the hydrofoil. When the second motor is shut down the motor and hydrofoil automatically drop into the water.

An apparatus for automatically raising first propulsion means on a boat, said boat having second propulsion means, comprising: (a) mounting means for mounting said first propulsion means to said boat such that said first propulsion means can move between a submerged position and an unsubmerged position when said boat is in the water; (b) hydrofoil means for raising said first propulsion means from said submerged position to said unsubmerged position when said boat is being propelled by said second propulsion means, said hydrofoil means being coupled to said mounting means, said hydrofoil means being adapted to be submerged when said first propulsion means is in the submerged position; (c) said mounting means providing for movement of said hydrofoil means and said first propulsion means such that said hydrofoil means maintains a relatively constant orientation with respect to a waterline of said boat so as to present minimal drag when said first propulsion means is in the unsubmerged position.
