What indicates a need to disable the red gear oil pressure at idle?

The need to disable the red gear oil pressure at idle is indicated when the pressure reads less than 15 PSI. In marine engine operations, maintaining proper oil pressure is crucial for ensuring the smooth functioning and longevity of the transmission system. If the oil pressure drops below the prescribed level, it can signal inadequate lubrication, which risks damaging internal components due to increased friction and heat.

In this situation, less than 15 PSI signifies a potentially serious issue that could lead to gear failure or other complications. Therefore, it is necessary to disable the system to prevent further damage and to investigate the cause of the low pressure.

Recognizing red flags like this is critical for engineers and operators to ensure the reliability and safety of the vessel’s operations.
