Temperature Gauge

The temperature gauge indicates the cooling water temperature inside the engine as measured in degrees Fahrenheit. The normal operating temperature will range from 140 degrees to 190 degrees. Engines with electronic fuel injection also have a control circuit inside the engine control module that will cause the engine to run at reduced speeds if the module senses that the engine is running too hot. 

If you notice that your speed has reduced during normal operation without reducing the throttle, monitor your temperature gauge. If the gauge indicates excessive temperatures during operation, slow down immediately and turn off the ignition. This indicates an engine problem that needs to be checked by the dealer!

Continuing to operate the boat while the temperature is above normal operating parameters may cause serious damage to your engine. Damage to your engine resulting from operating the engine in an overheated condition can be costly to repair. Such damage is not covered by your MasterCraft warranty!
