Deck installation is a complete propulsion package .It is a reliable and compact propulsion plant. The chassis carries the totally enclose propulsion system. The power of the diesel engine is transmitted to the rudder propeller through an elastic coupling ,a hydraulic clutch and a universal shaft. The chassis is constructed with a hydraulic system, an electric control box, daily fuel tank and so on system units. Installation is fast and simple because they are essentially self con rained .Only to connect the minimum boses and cables can make it available to obtain thrust. The deck installation unit merely has to be mounted and bolted onto a foundation of deck. Rudder propeller is mounted at the rear chassis.

The rudder propeller can be mechanically or hydraulically raised or lowered in vertical direction by means of a depth adjustment facility .The serves to ensure maximum propeller thrust at all vessel draughts by maintaining the correct propeller immersion.

For maintenance purposes, the rudder thruster can be pivoted out of the water to the rear hydraulically or mechanically by hand.
