摘要： An outboard motor includes a cooling water passage that guides cooling water to cool an exhaust passage and a cylinder unit. A cooling water intake port draws external cooling water into the cooling water passage. A water pump draws cooling water into the cooling water intake port and supplies the cooling water to the cooling water passage. A thermostat is arranged in the cooling water passage downstream of the catalytic converter and the cylinder unit. A first bypass passage is connected to a first connecting section provided on the cooling water passage. The first connecting section is provided along the cooling water passage at a position farther downstream than the catalytic converter and farther upstream than the thermostat.

摘要： An outboard motor includes an engine, and a top cowling and a bottom cowling that are arranged to cover the engine. A flow-joining pipe is connected to each exhaust port of a plurality of cylinders of the engine. A first exhaust pipe, a second exhaust pipe, and a third exhaust pipe are connected to the flow-joining pipe in sequence. The flow-joining pipe and the first exhaust pipe are connected generally at the same height as a bottommost of the cylinders of the engine. The third exhaust pipe is disposed above a topmost of the cylinders of the engine. A catalyst is disposed in a connecting portion between the first exhaust pipe and the second exhaust pipe so as to be housed in an upper end portion of the first exhaust pipe and in a lower end portion of the second exhaust pipe. The outboard motor is thus able to prevent water from adhering to a catalyst while avoiding any increase in size.

摘要： An engine is disposed in a top cowling. Burned gas produced in the engine is discharged to the outside through a first exhaust pipe, a second exhaust pipe, a third exhaust pipe, exhaust passage, and a exhaust passage. A catalyst is disposed to be housed in the first exhaust pipe and the second exhaust pipe. The first exhaust pipe and the second exhaust pipe are disposed in the top cowling. A fan is provided above the catalyst. As a result of this unique structure, a temperature increase in the cowling is prevented from being caused by heat radiated from the catalyst.

摘要： An outboard motor can comprise a cowling for covering an engine, a high pressure fuel supply system, and a low pressure fuel supply system. The high pressure fuel supply system can have a vapor separator tank and a high pressure fuel pump. The low pressure fuel supply system can have a low pressure fuel pump. A heat insulating chamber, defined from a space for accommodating the engine, can be formed within the cowling. The heat insulating chamber houses the low pressure fuel pump and the fuel filter.

摘要： A fuel supply device can have a low pressure fuel pump that supplies fuel to a vapor separator tank positioned adjacent to an engine from a main fuel tank disposed in a hull. An electrically operated primary fuel pump (e.g., a primer pump) and a check valve can both be positioned parallel to each other and between the main fuel tank and the low pressure fuel pump. A control device can be connected to the primary fuel pump for operating the primary fuel pump only for a preset fuel supply time when starting the engine is attempted and prior to the start of the engine.
