Marine Engine Mechanics

Marine Engine Mechanics

The military operates many types of watercraft from small motor launches to large ships. Many of these vessels are powered by gasoline or diesel engines. Marine engine mechanics repair and maintain gasoline and diesel engines on ships, boats, and other watercraft.

What They Do:

  • Marine engine mechanics in the military perform some or all of the following duties:
  • Repair and maintain shipboard gasoline and diesel engines
  • Locate and repair machinery parts, including valves and piping systems
  • Repair ship propulsion machinery
  • Repair and service hoisting machinery and ship elevators
  • Repair refrigeration and air conditioning equipment on ships
  • Repair engine-related electrical systems

Training Provided:

Job training consists of classroom instruction, including practice in marine engine maintenance and repair. Training length varies depending on specialty. Further training occurs on the job and through advanced courses. Course content typically includes:
  • Internal combustion engine theory
  • Repair of shipboard electronic and electrical machinery systems
  • Service and repair of fuel injection systems
  • Use and care of hand and power tools

Work Environment:

Marine engine mechanics work aboard ships, normally in the engine or power rooms. Sometimes they work in repair centers on land bases. Working conditions in engine rooms tend to be noisy and hot.
