An outboard motor includes a cowling with a cavity that receives a carburetor that supplies the engine with an air/fuel mixture. The carburetor has an air intake port. An air intake passage connects to this port, and bends partway around the carburetor. A resonance chamber communicates with the air intake passage and faces the carburetor to attenuate the noise from the carburetor intake port.
