Abstract
A marine engine has first and second banks of piston-cylinders, and first and second cooling water passages that convey cooling water in parallel alongside the first and second banks of piston-cylinders, respectively. A cooling water pump pumps the cooling water through the first and second cooling water passages. A first temperature-responsive valve is configured to discharge the cooling water from both of the first and second cooling water passages when the cooling water reaches a first temperature threshold. A second temperature-responsive valve is configured to discharge the cooling water from both of the first and second cooling water passages when the cooling water reaches a second temperature threshold that is greater than the first temperature threshold.
