摘要：
A marine outboard drive including an exhaust system that includes a baffle plate which is disposed across the low speed exhaust gas opening and which defines a plurality of ribs to break up the exhaust gas bubbles during idling for silencing. The baffle plate is formed as a sacrificial anode so as to offer galvanic protection and to permit ease of replacement.
