USCG Exam PracticeWatch duties, terminology, and instrumentation
Which of the following pre-departure checks is specifically associated with verifying that cooling water flow to the engine will not be restricted?
- A. Confirming the battery charge gauge reads 13.5–14 V at idle
- ✓ Confirming the raw-water sea-strainer is clearCorrect
- C. Confirming the oil dipstick reads at the expected level
- D. Confirming the battery isolator is switched on
Why B is correct
USCG Boatswain Manual Ch. 9 §9.2 lists clearing the raw-water sea-strainer as a pre-departure check. A clogged sea-strainer restricts raw-water flow used for engine cooling. The other listed items address electrical supply and lubrication, not cooling water flow.
