Abstract
An air intake system for an engine of an outboard motor includes air intake plenum chambers and corresponding air intake passages. Residual condensed fuel that can accumulate in the plenum chamber is guided to lower air intake passages through a slot at a predetermined rate to be delivered to combustion chambers inside the engine. The air intake system can reduce the likelihood that the plenum chambers will accumulate residual fuel above an acceptable amount and can allow the residual fuel to be more slowly delivered to the engine so as to evacuate the fuel without substantially altering the desired air/fuel ratio.
