Abstract
An outboard engine is disclosed that includes an idling chamber that communicates with a guiding outlet of a first exhaust path and that is open to the atmosphere. The idling chamber includes a cooling water communicating path that communicates with a cooling water supplying path, and a pressure adjusting valve that opens the cooling water communicating path when the value of the water pressure in the cooling water supplying path reaches a threshold value. When the value of the water pressure in the cooling water supplying path reaches the threshold value, the pressure adjusting valve opens and a portion of cooling water is guided to the idling chamber through the cooling water communicating path.
