Abstract: In an outboard motor tilt movement interruption device, when a tilt-up stop condition is established by a presence of an obstacle in a tilt-up movement range of an outboard motor and the obstacle and the outboard motor are equal to or less than a predetermined distance from each other, a circuit arranged to actuate a tilt device is cut off by an ON/OFF switch. On the other hand, when the tilt-up stop condition is not established, the circuit is connected. When the tilt-up stop condition is established during an operation of the ON/OFF switch, the circuit is cut off, and tilt-up of the outboard motor is stopped. Thereafter, when the tilt-up stop condition becomes canceled, the circuit is connected and tilt-up of the outboard motor is restarted.

Abstract: A watercraft propulsion device includes an engine, a drive shaft, a propeller shaft, a shift mechanism, an operation force transmitting mechanism, and a magnetostrictive sensor. The drive shaft transmits power from the engine. The propeller shaft is rotationally driven by power transmitted from the drive shaft. The shift mechanism changes a rotation direction of power transmitted from the drive shaft to the propeller shaft. The operating force transmitting mechanism connects to the shift mechanism and transmits a shift operation force to the shift mechanism to cause the shift mechanism operate. The magnetostrictive sensor detects a load acting on the operation force transmitting mechanism.

Abstract: A propulsion device includes a propulsion device main body, an attachment mechanism, and a steering mechanism. The attachment mechanism is arranged to attach the propulsion device main body to a hull such that the propulsion device main body turns right and left with respect to the hull about a swivel shaft. Further, the attachment mechanism is arranged to attach the propulsion device main body to the hull such that the propulsion device main body turns up and down with respect to the hull about a tilt shaft. The steering mechanism includes a motor and a transmitting mechanism. The transmitting mechanism is arranged to transmit a driving force of the motor to the propulsion device main body to turn the propulsion device main body to the right or the left. The attachment mechanism includes a housing space in which the motor and the transmitting mechanism are housed.
