An outboard motor includes a swivel bracket supporting a drive shaft housing such that the drive shaft housing is pivotable about an axis thereof and is movable in an axial direction thereof, a steering adjuster attached to the swivel bracket and configured to increase or reduce a rotational resistance force of the drive shaft housing against the swivel bracket, and at least one spacer mounted to the drive shaft housing at a position adjacent to at least one of both ends of the swivel bracket in the axial direction. In a state in which the spacer is mounted to the drive shaft housing, the drive shaft housing is restricted from moving in the axial direction with respect to the swivel bracket. A dimension from the swivel bracket to a rotation shaft of the propeller is changed by changing a mounting position of the spacer.

Outboard motor

A cover structure of an upper unit in which a power source of an outboard motor is provided, the cover structure includes a main body cover including a pair of divided covers connected to each otter, the pair of the divided covers being configured to be divided into each other in a left-right direction with respect to a traveling direction of a boat, an attachable and detachable cover that is attachable to and detachable from a part of an outer surface of at least one of the pair of divided covers and that includes a light transmitting portion in at least a part of the attachable and detachable cover, the light transmitting portion configured to transmit light, and a light emitter that is provided at a mounting position of the attachable and detachable cover and that includes a light source.

Cover structure

A boat propulsion machine includes a power source, a drive shaft, a propeller, a gear mechanism, a gear case, a tank configured to store a cooling liquid for cooling the power source, a heat sink configured to cool the cooling liquid, a cooling liquid passage connecting the power source and the heat sink, and a pump a pump configured to pump the cooling liquid to circulate through the cooling liquid passage. The power source, the tank, and the pump are provided at an upper portion of the boat propulsion machine. The gear case is provided at a lower portion of the boat propulsion machine. The drive shaft extends in an upper-lower direction between the power source and the gear mechanism. The heat sink is provided at a position lower than the power source and higher than the gear case in the boat propulsion machine.

The cooling device for a power source for a ship propulsion device that pumps up cooling water, from which foreign matters with sizes that cause clogging of a cooling water route have been removed, supplies the cooling water to a cooling water passage (), and discharges the cooling water to outside after cooling a power source () includes: a filtration device (A,B) provided in the cooling water route to filtrate foreign matters remaining in the cooling water, and the filtration device is of a cartridge type that incorporates a filter () for filtration disposed in a main water passage (P) and a valve member () configured to open and close a bypass water passage (P) and that is configured such that in a case in which clogging occurs in the filter, the valve member opens to cause the cooling water to flow via the bypass water passage.

An air intake structure for an outboard engine wherein air which is taken in from an air intake opening provided in an engine cover for covering the upper part of the outboard engine is supplied to and sucked into a throttle body. The engine cover has an air intake opening which is open at the front of the outboard engine in the forward movement direction and a lid member which can open and close the air intake opening. A space which connects the air intake opening and the throttle body is provided separated from an engine room.
