Question 1 of 27070

When water-cooled engines are installed on small passenger vessels, the cooling system __________.

🔍 Key Concepts

• 46 CFR Subchapter T requirements for machinery on small passenger vessels • Purpose of a raw water intake and hull strainer in a cooling system • Difference between raw-water cooled engines and closed fresh-water cooling systems

💭 Think About

• Think about what absolutely must be true for any water-cooled engine to run safely and reliably on a small passenger vessel. • Ask yourself which of the listed items are actually mutually exclusive and which can all exist together on the same installation. • Consider whether regulations usually specify only one acceptable method, or whether they allow more than one compliant arrangement at the same time.

✅ Before You Answer

• Check which options describe necessary operating conditions versus acceptable design options. • Verify whether regulations allow closed fresh water systems in addition to raw water systems on small passenger vessels. • Confirm whether the presence of a hull strainer is required whenever raw water is drawn through the hull.
