KHO/340/EN/1.0.0. 23
WARNING!
If an elevation collar is not used and the hatch is opened,
water will flood into the engine room, quickly sinking the boat.
CAUTION!
If water gathers in the bilge, the cause for this must be
determined immediately. Any possible leaks must be repaired
immediately. Water can damage e.g. the starter motor.
4.6. Hydraulic reversing deflector control system
For controlling the reversing deflector, the jet has a hydraulic cylinder which is
operated mechanically with a cable. The cable (figure 18, point C) operates the
valve regulator (point A). The cylinder gets its power from the pump which has
been integrated in the propulsion unit.
Figure 18. Hydraulic cylinder
In a stock delivery, the system does not include a control lever or a cable, so
their type varies depending on the boat manufacturer. However, the different
types of systems have the following things in common:
• The operation of the deflector is always separate from the throttle and the
gearbox.
• The stroke length of the cylinder is always the same.
• The incoming direction of the cable can be chosen freely.
The oil circulating in the system must be cooled down in order to prevent
excessive heating. This is done with a heat exchanger, which is integrated into
the frame of the propulsion unit (figure 19).
WARRANTY!
If the oil in the system is not cooled, the manufacturer is not
responsible for possible damages which derive directly or
indirectly from the oil overheating.
