Abstract： This paper investigates the recuring high cooling water temperature alarm and failure to reach rated RPM in the starboard main engine of a dual-engine propulsion patrol boat during sea trials. Systematic inspection revealed significant construction deviations in the starboard sea chest baffe plate，leading to insuffcient seawater intake during high-speed navigation.The cooling system's water supply capacity was restored to design specifications by redesigning the bafle plate structure and optimizing the seawater flow channel configuration. Post-modification trials demonstrated markedly improved cooling efciency under dual-engine synchronous operation.
Key words： power system; sea chest baffle plate; quality improvement
