Diesel engines are everywhere — ships and powerboats, most heavy transportation trucks, commercial / industrial strength generators, some personal vehicles, farming equipment, etc.

IYRS’ Marine Systems program spends approximately one month full-time on diesel engine training, primarily focusing on the marine diesel engines found onboard boats and yachts. However, the skills learned can be applied to other diesel engine uses and industries.

Introductory Diesel Engine Training

Marine Mechanic Students Working on Diesel EngineIntroductory marine diesel engine training covers the fundamental principles and operational needs of marine diesel engines:

  • Routine Maintenance Tasks
  • Commissioning and Decommissioning
  • Fuel and Lubrication System Service
  • Cooling System Maintenance and Service
  • Troubleshooting and Preliminary Diagnostics


Comprehensive Diesel Engine Training

Diesel-Engine-Outer-Limits-BoatsIn addition to all training listed above, a comprehensive marine diesel engine training program should also cover the following mechanical and electronic diesel engine fuel injection systems and engine drive systems:

  • Service and Diagnostics of Fuel Injection Systems
  • Problems Associated with Diesel Engine Performance
  • Theory of Operation and Design Features of Engine Drive Gears
  • Maintenance and Service of Mechanical and Hydraulic Inboard Engine Drive Gears
  • Problem Diagnostics for Marine Gear Units


Gasoline Inboard & Inboard/Outboard Engine Training

Teacher-Student-Working-On-Diesel-EngineGasoline inboard and inboard /outboard engines are studied in theory and practice.

  • Maintenance and Repair Procedures
  • Commissioning and Decommissioning
  • Basic Engine Needs Such as Fuel, Air, Compression & Exhaust for Both Carbureted and Fuel-Injected Engines
  • Routine Tuning Procedures & Use of Electronic Scanning Equipment
  • Proprietary Laptop-Based Software Programs to Perform Diagnostic Procedures on New Engine Electronic Fuel Injection Systems


Diesel Mechanic & Diesel Technician Job Expectations

Engine Used on a BoatDiesel mechanics & diesel technicians should be prepared to perform preventative maintenance, inspections and safety checks, as well as diagnose and repair problems with diesel engines. Diesel mechanics should be able to estimate time and material cost on repairs or jobs.

Diesel mechanics and technicians must fully understand all safety precautions involved in a repair process, and most often must be certified by completing a specialized training program. Marine diesel mechanics should be certified by the American Boat and Yacht Council (ABYC), a certification you can earn at IYRS.

Long hours, overtime or weekend work may be expected to accommodate needs of employer.
