An outboard motor which include an engine holder, an engine disposed above the engine holder in a state wherein the outboard motor is mounted to a hull, a mount unit including upper and lower mount devices for mounting the outboard motor to the hull and a bracket through which the upper and lower mount devices are mounted to the hull, an elastic thrust stopper disposed between the bracket and a body of the outboard motor, and a propeller driven in accordance with the engine operation. In such outboard motor, the distance between an axis of the upper mount device and an axis of the elastic thrust stopper both extending in a direction parallel to an axis of the propeller is set to be larger than a distance between axes of the upper and lower mount devices which extend in a direction parallel to the axis of the propeller.

Outboard motor

An outboard motor includes an engine holder, an engine which is disposed above the engine holder in a state of the outboard motor mounted to a hull and in which a crankshaft extends substantially perpendicularly, and an oil pan disposed below the engine holder. A drive shaft housing is disposed below the oil pan and is formed with an exhaust chamber and a water pump is driven by the drive shaft so as to pump up a cooling water. A cooling water passage is formed in the oil pan and the drive shaft housing to guide the cooling water pumped up by the water pump to the engine. A relief valve is disposed on the way of the cooling water passage so as to discharge the cooling water into the exhaust chamber.
