Why This
Course Matters
Recommended for all crew, It provides a clear, practical overview of how onboard systems work—engines, electrics, fuel, and water—without overwhelming detail.
What You’ll
Learn
How Boat Engines Work
Learn what makes marine diesel and outboard engines run, and understand the basic systems that keep them cool, fuelled, and operating properly.
What the Parts Do
Get familiar with the main components like the propeller shaft, gearbox, water pumps, fuel systems and what each componant part does.
How to Keep Engines Running Smoothly
Practice simple maintenance tasks like checking oil, changing filters, and recognising and identifying early warning signs before bigger problems occur.
Using Tools Safely and Correctly
Build confidence handling tools, understaning fastening and conducting hands-on repairs with guidance from experienced instructors.

Frequently
Asked Questions
Who is the Intro to Marine Engineering course for?
This course is designed for yacht skippers and crew on both sailing and motor yachts who want a practical understanding of marine engines and yacht systems—not for those pursuing a professional engineering career. If your goal is MCA engineer certification, AEC1 is the correct pathway, not this course.
Can I take this course together with AEC1?
No. This course overlaps significantly with AEC1, particularly in engine theory, systems, and maintenance principles. Taking both offers no added value and is not recommended. Choose one or the other based on your career goals.
What’s the difference between Intro to Marine Engineering and AEC1?
Intro to Marine Engineering is non-examined, hands-on, and operationally focused, ideal for skippers and crew. AEC1 is a formal MCA engineering qualification aimed at those progressing towards Engineer Officer certification. Different outcomes, different audiences.
Is there an exam or assessment?
No. There is no exam, test, or assessment. This is a skills-and-knowledge course, and participants who complete it receive a Certificate of Attendance, not an MCA certificate.
What engines will I learn about?
You’ll cover both marine diesel engines and petrol outboard motors, including:
- 2-stroke and 4-stroke operation
- Fuel, cooling, lubrication, air, exhaust, and electrical systems
This reflects what yacht crew actually encounter on board.
How practical is the course?
Very. Hands-on work runs throughout both days in the Galileo Engineering Workshop, including:
- Servicing a marine diesel engine
- Valve lash adjustment
- Pump, impellor, thermostat, and fuel system work
- Electrical wiring and battery testing
This is not a classroom-only course.
Will I learn fault-finding and maintenance skills?
Yes. A core focus is real-world fault finding and understanding:
- Reactive vs preventative vs predictive maintenance
- Fuel hygiene and lubrication oils
- Galvanic corrosion and bonding systems
These are critical for avoiding breakdowns at sea.
Does the course cover yacht systems and electrics?
Yes. You’ll gain a working understanding of:
- Shafting, propellers, bearings, and gearboxes
- Pumps, valves, and sea cocks
- Batteries, starter motors, solenoids, and basic electrics
Enough to diagnose issues and speak confidently with engineers.
Why is this course useful for all crew, not just engineers?
Because engine knowledge is an operational safety skill, not an engineering licence. Deck crew, skippers, and officers benefit from:
- Understanding early warning signs of failures
- Communicating clearly with engineers or shore support
- Performing basic maintenance and emergency troubleshooting
This course improves onboard competence, not job titles.
