🔍 Key Concepts

• Carefully read the Remarks column on the sample "List of Motors and Controls" sheet, especially any notes about heaters or thermostats in the motor. • Consider which motor is likely to be exposed to weather and moisture and therefore most in need of a device to keep its windings dry. • Look for abbreviations such as "SP HTR" or phrases that could mean a space heater or winding heater inside the motor housing.

💭 Think About

• For each option (A–D), first locate that motor application on the table and see exactly what is written in the Remarks column—does it mention anything about heaters in the motor? • Ask yourself which of these motors would normally be installed out on deck versus down in a warm machinery space; which one would logically require extra protection from condensation? • Compare the remarks for the deck machinery motor with those for the engine-room pumps; which one explicitly references a heater or thermostat associated with the motor itself?

✅ Before You Answer

• Verify which line item on the sheet corresponds to amidships mooring winch versus the main engine pumps and fuel oil transfer pump. • Confirm which remark specifically includes a reference to motor space heater, SP HTR, or similar wording about keeping the motor warm and dry when idle. • Before choosing, be sure you are basing your answer on the exact wording in the Remarks column, not just on general knowledge of where motors are installed.
