On small passenger vessels, cooling water for the exhaust lines from an internal combustion engine must be _______________.
AI Explanation
The correct answer is D) obtained from the engine's cooling water system or from a separate engine-driven pump.
On small passenger vessels, the cooling water for the exhaust lines from an internal combustion engine must be obtained from the engine's cooling water system or from a separate engine-driven pump. This ensures that the exhaust system is adequately cooled to prevent fire hazards and damage to the vessel's structure.
The other options are incorrect because: A) flushing and changing the cooling water periodically is not a requirement, B) using a fresh water storage tank or expansion tank would not provide sufficient cooling capacity, and C) chemical treatment is not necessary if the cooling water is obtained directly from the engine's system.
