A method of controlling an adjustable exhaust system for a marine engine includes receiving a vessel location of a marine vessel having an adjustable exhaust system and identifying a noise constraint based on the vessel location. A current exhaust mode of the adjustable exhaust system is identified. A determination is then made regarding whether the exhaust system is exceeding the noise constraint based on the current exhaust mode. If the noise constraint is exceeded, an instruction is generated to adjust the adjustable exhaust system to comply with the noise constraint.

An oceangoing vessel exhaust pipe coupling used to temporarily couple to an oceangoing vessel exhaust pipe. Installation and removal of the coupling only requires a simple mechanism with three translational degrees of freedom and one rotational degree of freedom, thereby enabling remote coupling. The coupling adapts to a wide array of exhaust pipe shapes and sizes. This is accomplished by a unique shape that allows stable and balanced resting position on top of an exhaust pipe as well as a two-chamber configuration, wherein the two chambers are separated by a permeable partition. Furthermore, the unique shapes of the chambers deflect the exhaust gas stream towards the outlet of the coupling, regardless of exhaust pipe style, thereby increasing capture efficiency and extending the life of an attached fabric flexible hose.

A method of controlling an adjustable exhaust system for a marine engine includes receiving a vessel location of a marine vessel having an adjustable exhaust system and identifying a desired position of the bypass valve based on the vessel location and/or a current time. If the bypass valve is not in the desired position, an instruction is generated to adjust the bypass valve to the desired position to change a noise level generated by the adjustable exhaust system.
