2.2.1. Steering
The boat is steered by turning the steering wheel. The connection from the wheel to the
steering lever can be either mechanical or hydraulic (figure 2.2.1-1). The lever moves
the nozzle through the shaft and the joint.
- Steering is possible when the power of the jet flow is sufficient. This is why the
engine must run on sufficiently high revs when steering. 1200-1800 rpm is a suitable
number of revolutions, depending on the engine.
- In sharp curves, turning the nozzle causes the boat to slow down. This is normal and
increases safety.
- The turning of the nozzle from one extreme position to the other takes ~2 turns of the
wheel.
2.2.2. Controlling
In models AJ 160 and AJ
180/185 a fully mechanical
system can be used, as long as
it is sturdy enough.
The reversing deflector can be
lowered in front of the jet flow,
changing its direction forward
and down. There are two
different types of deflectors.
Figure 2.2.2-1
Driving direction is controlled with the reversing deflector. The reversing deflector
is moved with the lever which is usually next to the throttle lever. With this lever, it
is possible to control the hydraulic system mechanically or the mechanical system
electrically.
