An outboard motor fuel supply device affording improved assembly and maintenance procedures. An outboard motor has an air intake manifold arranged on one side of the engine, and fuel flow path components that supply fuel from the fuel tank to the engine arranged together on one side of the air intake manifold.

Fuel system for outboard motor

An outboard motor air intake device having a throttle body is located essentially horizontally in front of the engine, and includes a surge tank located on a side part of the throttle body, and an air intake manifold with multiple air intake pipes which extend on one side of the engine from the surge tank to each of the cylinders. A throttle valve is located in the throttle body and the linkage mechanism that operates this throttle valve is located opposite to the engine's air intake manifold, so that the linkage is easy to assemble and maintain.

Air intake system for outboard motor

This invention is an outboard motor exhaust device compatible with a small, lightweight cylinder block, which simplifies the exhaust manifold assembly and allows greater precision of assembly. The engine of an outboard motor is located above an engine holder, and comprises a horizontally assembled cylinder head, cylinder block, and crank case. An air intake device is located on one side of the cylinder block, and the exhaust manifold comprising the exhaust device is located on the opposite side of the cylinder block from the air intake device. A side surface of the cylinder head and a side surface of the engine holder are coplanar and form a support for the exhaust manifold.

Exhaust system for outboard motor

An outboard motor comprises, in an installed or mounted state, an engine holder, an engine located to an upper portion of the engine holder, a drive shaft housing located to a lower portion of the engine holder for housing a drive shaft extending downward from the engine, and an oil pan formed to the engine holder, the oil pan being provided with a wall section to which steering brackets are secured through upper mounts. A first seal member is disposed at a mating surface portion of an upper surface of the drive shaft housing and a lower surface of the oil pan and a second seal member is disposed at a mating surface of an upper surface of the oil pan and a lower surface of the engine to thereby expose the drive shaft between the first and second seal members.
