Abstract
The engine (11) of a stern drive (10) is provided with a vacuum relief valve (28) to relieve any vacuum which may occur in the exhaust manifold (16), thus preventing water from entering the engine through the exhaust system. The relief valve (28) is connected to allow one-way flow from the intake manifold (15) to the exhaust system, thus providing an essentially closed system.
