🔍 Key Concepts

• Pre-start checks for internal combustion engines (diesel and gasoline) • Why lubrication (oil), cooling, and exhaust flow are each critical to safe engine operation • Consequences of missing any one of these checks on a small vessel

💭 Think About

• Ask yourself: If this engine starts running with low or no oil, what could happen and how quickly? • Consider what happens if cooling water is not circulating properly before and right after start—what are the risks to the engine? • Think about why being able to see exhaust discharge matters to you as the operator—what is it telling you about both cooling and combustion?

✅ Before You Answer

• Identify which options are basic, universal checks for any marine engine before starting • Decide whether checking only one system (like oil or cooling water) is enough to protect the engine and crew • Verify whether safe seamanship emphasizes a complete systems check or a single-item check before starting an engine
