(No tunnel, Control, Cable included)
The hydraulic motor is driven by a hydraulic pump. If a hydraulic pump and 
associated tank are already installed on board, then , in most cases, this 
assembly can be used for driving the bow thruster too.  In addition to the 
pump and the hydraulic stage tank, Vetus can supply the required load sensing 
and control devices, as well as the high pressure hydraulic hoses, complete with 
end fittings.
All these hydraulic bow thrusters may be fitted to fiberglass, steel or 
aluminum tunnels or used as a stern thruster using the appropriate installation 
kit
The three most powerful vetus bow thruster can also be driven in a safe 
manner using a specially prepared diesel engine, instead of pump on the main 
engine.
In this case, the matching hydraulic pump will be supplied as part of the 
powerpack.  Installing a powerpack on board can considerably reduce the 
required generator set capacity, by operating hydraulic functions which are 
normally electrically powered.
