Centre position
The centre position of the control lever corresponds to the ”idle” position of
the gearbox: even though the drive is on, the boat does not move. The centre
position is not absolute as it depends on the power of the jet flow. You can find
the centre position by testing during the first few driving hours.
TIP!
When the boat is not in use, it is advisable to raise the
reversing deflector into the upright position. This will protect
the cylinder rod and prevent it from collecting dirt, thus
increasing the service life of the seals. For long-term storage,
you can ensure that the reversing deflector stays in the
upright position by tying it from the lifting loop to the stern of
the boat.
3.3.2. Using the reversing deflector
When moving at low speeds, the reversing deflector is used to control the
boat's speed. Because the engine is being run at 500–1,000 rpm to enhance
steering, the boat may travel faster than desired. If this is the case, the
deflector can be lowered in front of the jet flow to reduce the thrust directed
towards the driving direction. This does not affect the steerability, which
remains good.
At high speeds, the deflector is not used to reduce speed. Instead, speed is
controlled with engine revolutions.
It is possible to turn the boat in place when the deflector is in the centre
position. When the nozzle is turned in the desired direction, the boat rotates
about its central axis.
When reversing, steering is inversed in comparison to driving forward. If
you want to reverse the boat to the left, you must turn the steering wheel to
