Diesel Engine
RYA/YA Accredited
This one day course provides an awareness of the main systems of a marine diesel engine and teaches the ability to take simple measures to prevent mechanical breakdown at sea and rectify defects which do not require workshop support. Mechanical failure is the main cause of lifeboat callout to yachts and motor cruisers. Basic maintenance and engine care may make sure you are not part of these figures.
A marine diesel engine (not necessarily in working condition) will be provided for practical session. There is no pre-course knowledge required.
