A A means of backfire flame control
B A lubricating oil pressure gauge and a tachometer
C Jacket water discharge temperature gauges
D All of the above
AI Explanation

The correct answer is D) All of the above. On small passenger vessels with gasoline engines, the regulations require the engine to be fitted with the following: 1) A means of backfire flame control, to prevent engine backfires from causing fires. 2) A lubricating oil pressure gauge and a tachometer, to monitor the engine's operating conditions. 3) Jacket water discharge temperature gauges, to monitor the engine's cooling system. The other options are incorrect because they do not include all the required equipment. The regulations mandate that all three of these components must be installed on gasoline-powered small passenger vessels.
