Abstract
An induction system for a marine engine is provided. The induction system includes at least one baffle positioned between an intake chamber and a combustion chamber of the engine. The baffle retards intake blow back, thereby reducing noise generated by the engine. The noise reduction protects sensors within the engine compartment from sonic energy damage.
