RYA Diesel Engine (Theory)
The RYA Diesel engine course is a serious must for anyone prepared to entrust their life or their family’s life to the humble diesel engine. Although normally very reliable, there are a number of common problems that will stop a diesel engine in its tracks. With proper training, many of these problems can be rectified easily.
Allabroad has a fully functional 3 cylinder Volvo MD20 30 diesel engine in its dedicated marina-side facility, and up to 4 different engines on various vessels to work with from 20hp to 300hp.

There is a big emphasis on emergency repairs at sea: one of the practical exercises is to actually re-plumb the fuel system to run from a separate supply and then start and run the engine directly, without using any of the vessel’s fuel or electrical systems. No other RYA Training Centre in Gibraltar comes close to offering this level of expertise or equipment.
