After checking the cooling water level, which item should be checked next in the engine startup process?

• A. Governor low oil button
• B. Over speed trip
• C. Crankcase protective devices are in the proper position, if equipped
• D. Low water

Answer: (C)

Checking crankcase protective devices in the proper position ensures the engine’s safety safeguards will function during startup. These devices guard the engine from damage by preventing or stopping operation if crankcase conditions are unsafe, so confirming their position before starting is a critical prestart step. The other options either aren’t standard prestart checks or aren’t necessary at this moment: the overspeed trip would be evaluated during testing after run, the governor low oil button isn’t a typical prestart requirement, and repeating a low-water check is redundant once it has already been done.
