Diesel Engine and boat maintenance

This two day course is based on the RYA Diesel Engine Course expanded to cover all the essential boat maintenance tasks that can be completed by the average boater without the use of specialist tools.

As well as the routine maintenance tasks the course covers simple fault finding on your engine, drive train and electrics.

The course has a number of “hands on” workshop sessions so it is suggested that you wear overalls or other suitable clothes that can get dirty. Stout footwear is essential. Protective gloves are provided.

Student numbers are restricted to ensure that everybody gets sufficient hands on experience.

The course covers the following topics:

1: Diesel Engine, Theory and Operation

2: The fuel system, operation, service and maintenance

3: The Air System, requirements and maintenance

4: The cooling system, types, operation and service

5: Lubrication system, service and maintenance

6: Other engine adjustments

7: Basic electrical system, operation, service, maintenance, basic fault finding and testing.

8: Basic tools and spares

9: Drivelines and stern gear, service and maintenance

10: Domestic water systems fault finding and maintenance

11: Hull Protection, Paintwork Maintenance and leaks through fittings

12: Winterising

The course is a mix of classroom and practical sessions and is held in our dedicated classroom at Debdale Wharf. Although safety boots are not required it is suggested that you wear stout boots or shoes (flip flops and sandals are not suitable). The practical sessions will also involve working with oil and diesel fuel, so overalls or old clothes are essential. Gloves and barrier cream are provided.

Hot and cold drinks are available throughout the day and lunch is provided. Please inform us in advance if you have any special dietary requirements.

If you are attending the course on you boat the instructor will be available after the course to look at any problems you may have and make recommendations on how to fix them.

Looking forward to the next course.


I enjoyed all of the course. Steve is very knowledgeable and knows his stuff. Thanks Steve


I just wanted to say another huge thank you for such an interesting, informative, confidence-building and fun weekend. Without any real idea of how the course would go and knowing so little about engines, I knew that by Monday I would know something more than I did on Friday; however I had no concept of how much you would be able to teach me. In my opinion you work very hard for your money from me and I felt it was excellent value. With only a truly basic idea of how an internal combustion engine works, I gave you very little to work with but I can honestly say I now feel I have a competent knowledge and ability which I am cautiously but keenly looking forward to using. Thanks also for the offer of follow-up advice if I need it and the copy of course notes which came via David yesterday.


  A most enjoyable weekend. The instructor was thorough, engaging, sympathetic & knowledgeable.


Whole course informative and instructor very knowledgeable making course enjoyable


I had a great experience over the weekend. Looking forward to applying new knowledge to caring for my boat. Booked another course today!


First class. We were fortunate to have two instructors!


Very enjoyable weekend. Brilliant


As a complete novice the course provided enough for me to feel confident to ‘have a go’


Would recommend. Well worth the time and money. Thank You!


Detail was excellent. Gave time to answer individual questions which was really helpful as it made content very real to our situations.


Great knowledge, enthusiasm and ability to answer questions on a variety of boats – thanks.


Great instructor – clear wealth of experience.


Very good. Taught in an easily understandable way. Very well paced


The instructors explained everything really clearly and the content was excellent. I'll be telling other boat owners in the marina about it.


The course was extremely comprehensive. I valued it all and appreciated the additional content the instructor provided.


Friendly and knowledgeable trainer, happy now to tackle all maintenance jobs on my boat


Would have come back for a third day I enjoyed it so much.
