A marine propulsion system configured to propel a marine vessel in a body of water. The marine propulsion system includes an engine and an exhaust system that conveys exhaust gas from the engine. A controller controls the marine propulsion system and includes a memory module that stores operating modes with corresponding sound profiles for controlling the marine propulsion system. An input device is provided for selecting one of the operating modes for controlling the marine propulsion system. Selecting a first operating mode causes the marine propulsion system to sound different than selecting a second operating mode.
