Abstract
A marine drive includes an engine; an exhaust conduit that conveys exhaust gases from the engine to an idle relief outlet on the marine drive, wherein the idle relief outlet discharges the exhaust gases to atmosphere when the marine drive is operated at an idle speed; and an idle relief muffler having a muffler inlet that receives the exhaust gases from the exhaust conduit, a muffler outlet that discharges the exhaust gases to the idle relief exhaust outlet, and a drain for draining water from the idle relief muffler. The muffler inlet conveys exhaust gases into the idle relief muffler in a direction that is oriented away from the muffler outlet and away from the drain, such that water in the exhaust gases is encouraged to separate from the exhaust gases and then drain from the idle relief muffler via the drain.
