In Indonesia. Thailand and Bangladesh the most common engines by far for small fishing craft, are the 5 - 15 hp range of multipurpose diesel engines used for water pumps, generators, power tillers and small tractors. The advantages of this type of engine, compared with the specially marinized diesel engine, is the low cost and easy availability of bot h engines and spare paris. Two methods for the installation of these engines have been developed and widely introduced. The conventional inboard installation, where the propeller shall is fitted through the keel structure, is used in boats operating from harbours or sheltered beaches. In the ‘longtail’ installation, the engine Sits on top of the transom and the propeller shaft goes through a long tube to the propeller. These two methods of installations are, however, not suitable for boa ts that have to land on surf-beaten beaches.p.38application/pdfFAOProject
