Diesel engine instructors 

The diesel engine maintenance course is one of the RYA's specialist one-day courses. In order to teach it you must qualify as an RYA diesel instructor, even if you are a qualified marine diesel engineer.

Length of course: 1 day organised centrally by the RYA.


  • The RYA Diesel Engine Course certificate
  • It is strongly recommended that candidates hold a RYA Instructor award prior to applying for the course in one of the following disciplines:- Cruising, Powerboat, Dinghy, Windsurfing or Inland Waterways, as this is a good indicator of their small boat experience and instructional ability. In exceptional circumstances, other instructional qualifications may be accepted.
  • A good knowledge of the operation and maintenance of marine diesel engines. Candidates who come from an automotive background should be familiar with both direct and indirect marine colling systems and salt water filtration.
  • Membership of the RYA (or the National Governing Body for your boating activity in your country of residence).

This is a one day combined course and assessment, revising your existing knowledge, providing advice for RYA diesel engine courses and assessing knowledge and ability to deliver an RYA diesel engine course. Candidates will be expected to be familiar with the operation and maintenance of marine diesel engines, direct and indirect marine cooling systems and salt water filtration.

Due to the short time available on this course, there is limited opportunity to develop a candidate's teaching technique or to fill any gaps in knowledge. As such, this course is a blend of assessing the candidate's knowledge, instructing ability and ensuring the structure and standard required of the course is understood. Candidates must therefore ensure they have sufficient underpinning knowledge prior to attending.

An effective instructor must have credibility with students and a genuine interest and engagement with the subject is essential for this. Questions from students will often stray outside the core syllabus or be concerned with seeking advice about equipment or situation. Without enthusiasm and a depth of knowledge far above the RYA syllabus, this credibility could easily be lost. It is difficult to quantify in writing exactly what this means but without extensive practical experience of the subject, candidates are unlikely to be successful of this instructor course.
