MARINE DIESEL technician career studies certificate


This program will prepare students for a career in the marine diesel engine repair industry. The entire maritime industry is growing at a rapid pace, and diesel technicians are needed in large numbers to keep the commercial fleets operating at their full capacity. Students will cover everything from diesel fundamentals to fuel and filtration to electrical and hydraulic systems. When complete, graduates will be well prepared for the American Yacht and Boat Council certification examination.



Career opportunities include Marine Diesel Technician, Marine Diesel Fuel Injection Technician, Marine Electrical Technician, and Marine Hydraulics Technician.
