Abstract
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.

A method of controlling an adjustable exhaust system for a marine engine, the method comprising:
- receiving a vessel location of a marine vessel having an adjustable exhaust system having a bypass valve that is controllable to bypass a portion of the exhaust system;
- identifying a desired position of the bypass valve based on the vessel location and/or a current time, wherein the desired position of the bypass valve is associated with a greatest noise level that does not exceed a noise constraint based on the vessel location or current time and/or does not exceed a user-instructed noise level;
- identifying that the bypass valve is not in the desired position;
- and
- generating an instruction to adjust the bypass valve to the desired position to change a noise level generated by the adjustable exhaust system.
An exhaust system for a marine engine on a marine vessel, the exhaust system comprising:
- a bypass valve that is controllable to bypass a portion of the exhaust system;
- a control system configured to:
- receive a vessel location of the marine vessel from a location tracking system;
- identify a desired position of the bypass valve based on the vessel location and/or a current time, wherein the desired position of the bypass valve is associated with a greatest noise level that does not exceed a noise constraint based on the vessel location or current time and/or does not exceed a user-instructed noise level;
- and
- generate an instruction to adjust the bypass valve to the desired position to change a noise level generated by the exhaust system.
