    • How to identify and rectify the more common faults which can arise
    • The systems and parts of the engine
    • How to bleed the fuel system
    • How to change the impeller
    • Routine maintenance such as changing filters
    • Winter lay up procedures
    • Engine electrical systems
    • This one day course, which requires no previous experience is highly recommended to anyone who sails a yacht with an engine or who is a motor cruising enthusiast.

    All equipment to complete the course will be provided. You just need to bring a notepad. Tea and coffee is provided and you can get lunch from the Village which is a short walk away. Alternatively you can bring a packed lunch to eat in the classroom.

    These are a few of the questions we get asked by people booking on the RYA Diesel Engine Course. If you have any further queries or are unsure whether this is the course for you please call us on 01243 432485 and we will be only too happy to chat to you.

    What time does the course start and finish?

    Typically we start at 9.00am and finish at about 5.30pm with an hour break for lunch

    What do I need to bring?

    You just need to bring a notepad with you and wear old clothes or overalls and if you have your own boat it may be useful to bring your engine manual so that the instructor can go through any engine specific queries.

    Where is the course held?

    It will be held at classroom 2 in Emsworth Yacht Harbour, Thorney Road, Emsworth, Hants PO10 8BP

    What qualifications or experience do I need to complete the RYA Diesel Engine Course?

    You do not need to have any qualifications or knowledge of diesel engines to attend this course.

    Are there any exams?

    There is no exam at the end of this course so just enjoy it without the worry of being tested at the end of the day.

    What qualification will I get once I have completed the course

    On successful completion of the course you will be issued with the RYA Diesel Engine Course Certificate.

    How many people will there be on the course?

    We have a maximum of 5 people on a course, so you will get lots of individual attention from the instructor.

    Who is a typical RYA Diesel Engine Student?

    It is difficult to say what a typical student looks like but we often find that students are:

    •  Boat owners who wish to be able to understand more about their engines and to be able to deal with the ,more common problems that arise.
    •  People who wish to be more useful crew members by gaining a greater understanding of boat systems.
    •  People who may be planning a career in the marine industry and wish to improve their overall knowledge.

    What kind of engine do you use?

    We use a marinised Yanmar engine during the training. This won’t necessarily be the engine you have on board so you are encouraged to bring along your own engine manual so that the instructor can go through any specific queries you may have.

    Really enjoyed the course & Les was excellent & full of helpful personalised tips. Thank you
    David Chinn
    I completely loved the Diesel Course today - Les is a really top teacher and I learnt so much!!! I'll definitely be back for more training!
    Fleur Whitlock
    We wanted to let you know how excellent we thought the diesel engine maintenance course was on 23rd June. Les was a first rate teacher and taylored the course to suit our engines which was so helpful. He also gave us lots of useful tips related to the engine and some which were indirectly related. My cousin, David, said the course was much, much better than he was anticipating - 'Brilliant' was the adjective he used. My son, Tom thought it was extremely interesting - high praise from an 18yr old! Please could you relay our thanks and appreciation to Les. We have booked our ferry to go and sort out the engine sooner than planned and we are so glad we came on the course!

    I am sorry not to have sent a message straight away to let you know that I thought that the Diesel Engine Course was excellent. Les was very good, and patient with us. I learnt a lot, and now feel more confident. I have found the engine manual which was hiding on board my boat with a pile of other stuff, and in fact I have now found a box with most of the spares for the Volvo 55 that I might need. I will get all the other things, and then hopefully will have no problems on the sail round to the mediterranean in August.

    Thank you for an excellent course on Saturday - Les was a superb instructor and I really learned a lot. I wish the course had lasted longer - there is so much to learn! Les was a fount of knowledge.
    George
    Quick note to say many Thanks for an excellent course on Monday. I now can't wait to get my hands on my diesel engine and pull it apart....safe in the knowledge that I can put it back together again. Les was excellent, please send him my best wishes.
    Nick Child
    Just to let you know I really enjoyed the diesel engine course and Les was such a good teacher that the day flew past.
    Sally Cholmondeley
    The diesel course was absolutely fantastic, what a great instructor. I learnt so much about my engine.
    Toby Norman
    Just to say thank you for providing such a great Diesel Engine Course on Saturday. Les was fantastic, and made what at first seemed very daunting into a day of relaxed learning (the best kind). I think that it has prompted Felicity and I into thinking about doing some more RYA courses
    Annabel Wilkins
    Another great training session today with Andy Johnson on boat electrics, following yesterdays equally superb day on Diesel Engine Maintenance presented by Les Cox.
    Martin Langan
    I learnt so much and it certainly has given me the confidence to tackle any issue with my engine, especially if at sea.
    Tony Hughes
    I just wanted to pass on my thanks to Les for the way he delivered yesterdays Diesel Engine Course. It was hugely informative and very hands on. He also included a host of additional practical tips which will be invaluable when I purchase my own yacht.
    David Macfarlane
    The RYA Diesel Course run by Emsworth School of Navigation was an amazingly packed day. Our tutor Les Cox ran through the systems he would be covering and I wondered if this would be too technical for me but he went through every part of the specification in a methodical way and we were able to handle and study the smaller engine parts. Les soon had us changing filters, checking the impeller, checking and fitting the drive belt, bleeding the fuel system, battery management, replacing a temporary head gasket and discussing fuel management. Having a ratio of 1 tutor to 5 students meant we had some personal tuition and were able to share our experiences. I really enjoyed this course and think it was great value for money.
