The basic includes turbocharged intercooled engine model and turbocharged model, and the turbocharged intercooled models are the same as truck engines, but adding marine special spares, such as marine intercooler, sea-fresh water heat-exchanger, monitor, PS8500 fuel injection pump(with parking electromagnet),sea water pump, SAE1# flywheel case, 14'flywheel, and flywheel connecting flange, supporter, the installment size is 740*1089.2.
the distance from crankshaft center height is 135.
The fishing boat used engines based on the basic used have been changed into 4 slots fishing pulley, connecting flange(M14*1.5), diesle filter installed in the air-intake pipe and also add diesle pre-filter installed in the air-intake pipe, the installing size is 694*1145.5*140cm.
