Intake manifold of outboard motor

摘要

An outboard motor is mounted with a multiple-cylinder engine and an intake air is distributed by an intake manifold to respective cylinders of the engine. The intake manifold is formed of synthetic resin and comprises a surge tank and a branch including a plurality of branch sections extending from the surge tank to the respective cylinders. The surge tank and the branch constitute an intake manifold body which is divided along a flow direction of the intake air flowing in the branch sections.
