  • Method and system for controlling the exhaust gases from an engine
    Patent number: 8808045
    Abstract: A method for controlling the exit of exhaust gases from an engine which is used to power an underwater propeller drive arranged at the hull bottom of a boat is provided. According to the method exhaust gases are allowed to flow from the engine through an exhaust channel and exit through a first underwater exhaust outlet in the underwater propeller drive. According to the method, if the engine is running and the transmission of the propeller drive is in neutral position, a second underwater exhaust outlet is opened for letting exhaust gases in the exhaust channel exit in a position closer to the hull bottom of the boat than the first underwater exhaust outlet.
