The normal operating temperature for a 5.7L GM marinized engine is typically between 160 and 175 degrees Fahrenheit (71 to 79 degrees Celsius). However, the exact operating temperature can vary depending on several factors, including the specific engine model, the boat's operating conditions, and the type of cooling system used. It is important to consult the manufacturer's guidelines for the specific engine to determine the recommended operating temperature range. Temperatures from 190F up to the engine’s over temp alarm should make you nervous. The over temp alarm for a 5.7L GM marinized engine typically sounds when the engine's temperature rises above 220-240°F (104-116°C).
Continuing to operate the engine at this temperature can lead to various risks, including engine damage, reduced engine performance, and potential safety hazards due to the engine overheating. If the over temp alarm sounds, it is recommended to evaluate your safety conditions and then shut down the engine posting the appropriate notifications for stranded boat conditions while you determine whether its logical to investigate the cause of the overheating issue or consider a tow.
