摘要： A thermostat includes an annular flange extending in radial directions and surrounded by a cylindrical large-diameter portion of a housing inner surface, and a frame extending in axial directions from the flange. The thermostat further includes a sealing member that hermetically seals the gap between the flange and the inner surface. The sealing member includes an annular outer peripheral portion sandwiched in the axial directions by the inner surface and a thermostat cover inside the large-diameter portion, and a plurality of protruding portions extending outward in the radial directions from the outer peripheral portion toward the large-diameter portion. The thermostat is disposed inside a housing that defines a portion of a cooling water passage, and opens and closes the cooling water passage according to the temperature of cooling water inside the cooling water passage.

摘要： An outboard motor includes a drive source, a drive shaft, a propeller shaft, a first case, a second case, a third case, a bearing, and a bearing housing. The drive shaft extends downward from the drive source. The propeller shaft is connected to the drive shaft and extends in a front-rear direction of the outboard motor. The first case houses the drive source. The second case houses the propeller shaft. The third case is between the first case and the second case in a vertical direction of the outboard motor. The bearing rotatably supports the drive shaft. The bearing is between the first case and the second case in the vertical direction and outside the third case. The bearing housing supports the bearing. The bearing housing is between the first case and the second case in the vertical direction and outside the third case.

摘要： An outboard motor includes an engine, a cooling water passage, a pump that is driven in conjunction with the engine, an inlet water passage that branches from the cooling water passage, an oil cooler, an outlet water passage, a first thermostat located in the cooling water passage, and a second thermostat. The pump takes outside water into the cooling water passage. The oil cooler includes a water-storing space into which water in the inlet water passage is taken. The outlet water passage is connected to an outlet of the oil cooler. The first thermostat increases and decreases the flow rate of water flowing through the engine. The second thermostat is located at the outlet or at the outlet water passage, and increases and decreases the flow rate of water flowing through the outlet water passage.

摘要： An outboard motor includes an engine including a crankshaft that is rotatable about a rotation axis extending in an up-down direction, and a crank chamber that houses the crankshaft. The outboard motor includes an oil pan including an oil retaining portion, a cooling water passage disposed along an outer wall surface of the oil retaining portion, an oil recovery passage extending downward from the crank chamber to lead lubricating oil inside the crank chamber to the inside of the oil retaining portion, and a guide member. The guide member includes a shielding portion disposed inside the oil recovery passage so as to be located over an opening of the oil retaining portion, and a guide hole disposed inside the oil recovery passage so as to be located over an inner wall surface of the oil retaining portion. The guide member is configured to guide lubricating oil to the guide hole by the shielding portion and allow lubricating oil to flow down to the inner wall surface of the oil retaining portion from the guide hole.

摘要： An outboard motor includes an exhaust pipe that includes an outer wall section, an inner wall section, a coolant passage, and a constricted section. The inner wall section is arranged inward of the outer wall section. The coolant passage is arranged between the outer wall section and the inner wall section. The constricted section is configured to constrict a flow cross section of the coolant passage. A catalytic converter is housed in the exhaust pipe. A temperature sensor is installed in the constricted section and measures a temperature of a pipe wall of the exhaust pipe.
