Sample Marine Service Technician Practice Questions

Try these questions from our free Marine Service Technician practice tests. The correct answer and an explanation follow each question.

1. When a marine technician performs a resistance test on a fuel sender unit, what must be done FIRST?

   • A. Connect the ohmmeter with power applied to the circuit
   • B. Disconnect the sender from the circuit before measuring resistance
   • C. Measure resistance with the fuel tank completely full
   • D. Apply 12V to the sender before testing

   Answer: B. Disconnect the sender from the circuit before measuring resistance

   The component must be isolated from the circuit before resistance testing; measuring resistance in a live circuit will give inaccurate readings and may damage the meter.

2. A marine technician performs a compression test on a 4-cylinder engine and finds cylinders 2 and 3 have equally low readings. What is the most likely cause?

   • A. Worn piston rings in both cylinders
   • B. Blown head gasket between cylinders 2 and 3
   • C. Stuck open intake valves on both cylinders
   • D. Incorrect valve timing

   Answer: B. Blown head gasket between cylinders 2 and 3

   Adjacent cylinders with equally low compression indicate a blown head gasket between those cylinders, allowing combustion pressure to leak between them.

3. An inboard marine engine vibrates severely at all RPMs. The engine mounts appear good. What should the technician inspect next?

   • A. Carburetor jetting
   • B. Propeller for damage or imbalance
   • C. Distributor cap and rotor
   • D. Engine oil viscosity

   Answer: B. Propeller for damage or imbalance

   A damaged, bent, or imbalanced propeller is a leading cause of whole-RPM-range vibration in inboard installations after engine mounts are verified good.

4. When performing a cylinder leakage test on a marine engine, a reading of 25% leakage is found. Air is heard escaping into the crankcase. What does this indicate?

   • A. Blown head gasket
   • B. Worn or broken piston rings
   • C. Leaking intake valve
   • D. Cracked cylinder head

   Answer: B. Worn or broken piston rings

   Air escaping into the crankcase during a leakdown test indicates worn or broken piston rings allowing combustion gases to bypass the piston.
