Technical Examples

An engine air intake device for an outboard motor includes a plurality of main intake pipes corresponding to each cylinder. First and second branch pipes extend from an upstream end of each main part. The first branch pipes are longer than the second branch pipes. The second branch pipes each include a valve and are selectively closed. The first branch pipes open into a first surge tank. The second branch pipes open into a second surge tank that is formed separately from the first surge tank. In operation, the valves of the second branch pipes are open when the engine is operating in high engine speed and are closed at low-to-medium speeds.
