An outboard motor has an adapter plate that supports an internal combustion engine, a driveshaft housing disposed below the adapter plate, and a lower cowl. A lower cowl volume is defined between the adapter plate, cowl and driveshaft housing. A lower cowl volume inlet is configured to supply idle relief exhaust gases to the lower cowl volume and a lower cowl volume outlet is configured to discharge idle relief exhaust gases from the lower cowl volume to atmosphere. The lower cowl volume is configured to cause expansion of the relief exhaust gases prior to discharge of the idle relief exhaust gases to atmosphere.
