What is the jacket water op temperature range for the engine?

The jacket water operating temperature range for the engine of the 45-Foot Response Boat-Medium (RB-M 45) is indeed between 140 to 185 degrees Fahrenheit. This temperature range is essential for maintaining optimal engine performance and ensuring efficient cooling throughout operation.

The jacket water system is crucial as it circulates coolant around the engine to absorb heat, preventing overheating and promoting lubrication. Operating within this specified temperature range helps to control thermal expansion and maintain safe operating conditions, which in turn supports the longevity and reliability of the engine components.

Temperatures below this range could lead to inadequate cooling, potentially causing engine overheating during operation, while temperatures above the upper limit can indicate extreme conditions that could lead to engine damage. Thus, adhering to this temperature range is vital for the safe and effective functioning of the vessel's engine.
