🔍 Key Concepts

• Small passenger vessel machinery requirements in 46 CFR Subchapter T • Purpose of exhaust cooling water on small diesel/gas engines • Difference between raw (seawater) cooling and closed freshwater cooling systems

💭 Think About

• Think about where a reliable, continuous source of cooling water would normally come from on a small passenger vessel’s main engine. • Consider which option would be practical and automatically available whenever the engine is running, without needing crew intervention. • Ask yourself which choice matches typical small-boat practice: does exhaust cooling water usually come from potable tanks, chemical treatment, or directly from an engine-related pump/system?

✅ Before You Answer

• Verify which option describes a source of water that is automatically supplied whenever the engine operates. • Eliminate any option that would reduce potable water supply for passengers or domestic use. • Check which choice aligns with the normal design of raw-water cooled exhaust systems on small marine engines.
