Learn how to prevent and solve diesel engines failures on this one day introduction to diesel engine maintenance.

Mechanical failure is the main cause of rescue call-outs to yachts, but some knowledge of basic maintenance and engine care will help to ensure you are not part of this statistic. Most engine problems can be avoided by taking simple precautions and you don’t need a detailed mechanical knowledge.

This course teaches you how an engine works, how to keep it healthy by using basic check and maintenance procedures and how to get it started again in the event of a breakdown.

Key learning points: The four stroke cycle, fuel, cooling and air systems, engine electrical systems, spares and tool requirements, winterisation and servicing.
