Abstract
A stern drive arrangement is for propelling a marine vessel in water. A diverter valve is movable into and between an open position in which the exhaust gas is allowed to flow through the above-water outlet via the secondary exhaust conduit and a closed position in which the exhaust gas is at least partially prevented from flowing through an above-water outlet via a secondary exhaust conduit. Via a bypass conduit, the exhaust gas in the secondary exhaust conduit can bypass the diverter valve and discharge to atmosphere when the diverter valve is in the closed position.
