A mechanism for tilting an outboard motor. The mechanism has an outboard motor which is attached to a hull so as to be tilted up and down, a cylinder for driving the outboard motor to change a posture of the outboard motor, and a linkage to connect the outboard motor and a rod of the cylinder. The cylinder itself serves as a central shaft, around which the outboard motor is tilted up and down. Since the cylinder has a single-walled construction, the mechanism of the present invention is simple and can be economically manufactured.

Each of control boxes has an operation lever and an element moving together with the operation lever and a primary sensor for detecting the position of the moving element are arranged in each of the control boxes. A drive unit includes a motor, a movable rack driven by the motor and a secondary sensor for detecting the position of the moving rack. A control circuit serves to drive the motor to make any positional difference of the moving element and the movable rack zero. In a case where the position of the moving element does not coincide with that of the movable rack even after a predetermined time period goes by from when the rotation of the motor is started, current supply to the motor is temporarily stopped and then again started. When the control boxes are to be changed over from one to the other, this changeover is allowed only in a case where the control boxes which are to be changed over from one to the other and the drive unit are in neutral position. The drive unit includes a manual gear which can be toothed with the movable rack, and a handle for rotating the manual gear when something wrong happens to the electric system.

In an apparatus for fixing a cowling assembly of an outboard motor, a base member is provided with a locking plate and an intermediate plate. The locking plate has a jaw portion and a stay-receiving face for clamping a stay when the cowling assembly is locked. The intermediate plate has a first stopper portion, a second stopper portion and a cam-receiving portion, In the locked state of the cowling assembly, the first stopper portion is engaged with the locking plate. In the released state of the cowling assembly, the second stopper is engaged with the locking plate. The intermediate plate is moved in a direction to release the cowling assembly, by means of an operation lever arranged at a front portion of a bottom cowling. A spring interposed, in its compressed form, between a spring seat of the locking plate and a spring seat of the intermediate plate urges the locking plate and the intermediate plate to rotate in such a direction as to engage the locking plate with the stopper portions. The operating lever is connected to an intermediate plate of a rear locking mechanism.

A body has a guide members extending along the axis of the body. A pair of racks held by the body are movable along the guide members. The first rack is connected to a first remote control unit through a first cable. The second rack is connected to a second remote control unit through a second cable. When one of the first and second racks is moved from a reference position, the lock members locks the movement of the other rack. An intermediate gear is arranged between the first and second racks. An interlocking member is connected to the intermediate gear. When one rack is moved, the intermediate gear is moved in the same direction as the moved rack. The movement of the intermediate gear is transmitted to equipment to be controlled through the interlocking member.
